UNMATCHED HEATINGThe 1100 square feet of heating coil surface in our vertical tanks is significantly more heating surface than you will find in vertical asphalt storage tanks built by others.

Coil heating surface area is directly related to how fast you can raise the temperature of asphalt in the tank. So when an asphalt supplier fills the tank with a “cold” load you won’t have long delays while it reaches the required temperature.

We achieve the extraordinary amount of heating surface by using finned pipe. This reduces the number of coils needed and conserves space in the bottom of the tank. Coils without fins would occupy a significantly greater height in the tank and signifi-cantly reduce the usable volume of the tank.

Just for the record the height of the two-layered finned coil above the bottom of our tank is only 11-5/8 inches. But if the same coils had no fins, seven layers with a height of 40-3/8 inches would be needed. The coils in some tanks on the market have

much greater heights, which may severely limit the usability of the tank.

Remember, the asphalt level in the tank needs to always totally cover the heating coils to prevent coking. So you always need to refill the tank before the asphalt level is lower than the topmost coil.

Moreover mixers in tanks filled with PMAC do not work adequately when coils are several feet in height.

To appreciate just how much coil height affects us-ability consider that each inch of height above the coils in a vertical tanks is equal to 58.8 gallons.

So our heating coils are unmatched because they provide an extraordinary amount of heating sur-face while minimizing loss of usable space.

Arby’s SandwichesThis is not the original editorial column I wrote for this edition of AsphaltPro. You’ll have to check the June/July issue for tips on strengthening asphalt while lengthening your compaction window. No, this month, I needed to modify the content. The asphalt industry has lost a faithful friend, and I want to use this platform to share something lovely about Dr. J. Don Brock.

Any number of trade publications and economist-forecast newspapers will give you a rundown of Dr. Brock’s many achievements, including the 100 patents he owned. One source referenced the fact that Fortune 500 CEOs tune into Astec public quarterly statements to get a bead on the world economy. His nomination to the ARTBA Hall of Fame crossed my email account as I was one of the judges that year, and the list of accom-plishments for the man was mind-boggling.

Of course, the measure of a person isn’t in the num-ber of associations or CEOs who look up to him or her. As Richard Schreck, executive vice president of the Vir-ginia Asphalt Association told NAPA ActionNews in March, “Most people, if they are lucky, will only come to know one or two truly great men in their lifetime. Don Brock was such a man — a quiet genius with a great passion for and com-mitment to the asphalt industry. He was an unassuming man of great personal and profes-sional integrity who throughout his life mentored so many with humility, kindness and re-spect; always willing to listen and encourage.”

I consider myself blessed to have known Dr. Brock. He had been inducted into the Asphalt Pavement Hall of Fame in 1995, three years before I entered the industry, yet he was willing to answer my questions while I worked for an asphalt magazine. It didn’t matter to him that I was new to the industry; he was pleased to help me learn something and understand it.

Dr. Jay Winford, chairman of the NCAT board of directors and president of Prairie Con-tractors Inc. also shared that sentiment with NAPA ActionNews, stating, “Not only was Don Brock a great innovator within the asphalt industry, he was a great friend and mentor. He was certainly a chief engineer to both my personal development and company success. He taught me that the game of life was to create a business, but the meaning of life was to help others and make a difference.”

When the Asphalt Pavement Association of Indiana inducted Dr. Brock into its hall of fame a few years ago, John Ball and I visited with him on the tradeshow floor. He kindly re-sponded to John’s inquiry about his health, letting us know that he was moving forward and continuing to do all he could with each day. That kind of spirit was the man’s hallmark. And then Dr. Brock, who had the weight of the world on his own shoulders, looked John in the eye and asked how he was holding up after the passing of his wife. The men spoke together for a moment, merely sharing what was more important than the business around them.

As for the Arby’s mentioned in the headline this month, the full story is something che-mo/radiation patients can fully appreciate. That craving is pretty strong when it comes on, and I was tickled when I learned that Dr. Brock preferred the fast food to the fancy stuff at one of the conferences we were all attending. He didn’t take me up on my invite to ditch the luncheon for the Arby’s nearby, but I bet there’s time for yummy Arby’s sandwiches by some sort of glorious, golden asphalt roadway with a crew of old friends in Heaven.

Stay Safe,

Sandy Lender

safety spotlight

Handle Binder SafelyWe all know asphalt binder is a

key component in our mixes. How we handle binder is not

only critical for quality, but also for our safety. Many workers come into contact

with this hot liquid on a daily basis such as employees at the refinery, tanker drivers, plant personnel, and quality control techs to name a few. Over the years I have heard of and been witness to injuries from han-

dling hot liquids, and in most cases the ac-cidents could have been prevented by fol-lowing safety best practices.

An example of this came a few years ago when a plant operator I worked with—

By JArrett WelCh

the safe sampler from Maxam equipment is one example of the strides our industry has made in implementing best practices for the safety of QC/QA techs at the plant. this product is a totally enclosed sampling system. An access door interlock keeps the valve closed while the QC tech places or removes the sampling container. if the safety door isn’t closed, the sampling control valve can’t be opened to let AC flow into the sampling container.

safety spotlight

we’ll call him Louis—was unloading the transport tanker. When Louis went to disconnect the line from the tank, some-thing went wrong with the shut-off valve. The material blew back covering him with hot liquid binder. Fortunately for Louis, he used his safety training and Person-al Protective Equipment (PPE) to come away without injury. Prior to unloading the tanker, Louis put on his PPE, which consisted of a hard hat with a face shield, and a rubber-insulated long cover coat and gloves. These protected him from di-rect contact with the binder. Louis react-ed quickly to the situation and was able to control the blow-back and prevent others from coming into contact with the ma-terial. Management was relieved to hear Louis was not injured, but also wanted to assure this did not happen again. He then became part of the safety team within the company and spoke of his experience at future safety meetings.

As workers, we need to be vigilant when working with this material. We need to be prepared for an equipment failure, but also for human mistakes. The human ele-ment can put us at risk for injury. As hu-mans, we must guard against complacen-cy when performing routine tasks and not relax because we have repeated a task so many times without injury. When this oc-curs, we reduce our preparedness to re-act to the situation. Not only do we want to prepare ourselves with the correct PPE for the task, but we also need to prepare in our minds how we are safely going to per-form the task and what we are going to do should something go wrong.

In the example above, Louis understood the risks involved in the process of per-forming his duties. How we position our bodies when working with hot binders can make a difference in injury prevention. Standing to the side of the hose instead of directly in front of it likely minimized the contact when the valve failed and the hose was released. As a QC technician in the ear-ly days of my career, I had to sample bind-er during production from a nozzle that was directly tied into the feed line entering the drum. These sampling nozzles at times were not in a place that was easy to get to. Regularly, I had to use a ladder to get to the pipe where the nozzle was. I learned quick-ly how hard that was to do safely. Anyone who has sampled liquid AC this way knows that it takes a little bit of time for the bind-er flowing through the pipe to heat the cooler material in the nozzle. There is a de-lay from the time the nozzle is turned to when material begins to flow. Once it does start flowing, it comes in a rush.

Since those days, I have seen where we as an industry have modernized our op-erations for safety. Valves and nozzles are in easy-to-reach locations with stairs and railing to protect workers from falls. Some processes have become automated. Stan-dards and protocols have been developed to inform and guide us. PPE is more read-ily available, and training our employees has become paramount. Yet, it is still up to us as individuals to use these tools for our safety and the safety of those around us. Every day when we perform tasks related to our job we need to evaluate and identify the risks, determine how we will mitigate those risks, and implement the action.

negligible percentages—proceed with common Senseit was brought to our attention that an indus-try publication recently printed an article with an overview of how departments of transporta-tion (dOts) and contractors need to handle the extremely rare scenario where an old pavement constructed with asbestos fibers as an experi-mental additive needs to be removed. the head-line and image garnered attention that the neg-ligible scenario did not deserve. A spokesperson for the national Asphalt pavement Association (nApA) has offered the following statement to set the record straight.

“According to Mundt et al. (2009), only eight states reported having used asbestos in hot-mix asphalt and none did so regularly. "no state re-ported current or historical use of asbestos in hMA for mainline road paving, although eight states (Florida, indiana, iowa, Minnesota, new york, Ohio, pennsylvania, and Washington) re-ported infrequent low-volume use, with earli-est and most recent use dates reported as the 1940s and the 1970s, respectively." the same paper notes some additional testing and use of asbestos fibers in asphalt in those and a few oth-er states, but it was far from a universal prac-tice. [Mundt, d.J.; K.M. Marano; A.p. nunes; & r.C. Adams (2009). A review of Changes in Composition of hot-Mix Asphalt in the unit-ed states.Journal of Occupational and envi-ronmental hygiene, Vol. 6, no. 11, pp. 714-725. dOi:10.1080/15459620903249125]

“ideally, the dOts in each of those states have a good idea of the rare instances when and where asbestos fibers may have been used and it can, as penndOt did in this instance, put in place precautions to make sure workers and the pub-lic are kept safe. Absent dOt acknowledgment or identification, if a company has a reasonable suspicion (based on the location of a job, the pavement structure type, or the date the origi-nal pavement layer was placed) that they might encounter asbestos during milling, core samples could be taken, analyzed, and then appropriate safety measures could be implemented in the very rare case asbestos is actually present.

“As the article noted, only 55 miles of penn-sylvania roads contain asbestos out of more than 100,000 miles of asphalt surfaced roads; that's less than 0.055% of pennsylvania's roads. Gen-erally, these pavements were experimental, may have predominantly included bridgework, and appear to have been documented by penndOt. According the pennsylvania Asphalt pavement Association, the typical process is to only over-lay (and not mill) a pavement layer known to in-clude asbestos.

“Clearly this is an extremely unusual situation and one that only affects a small number of older pavements.”

Maintain Equipment By AsphAltprO stAFF

Copy and use this—or a similar—checklist for pre-shift walk-arounds.

When the mechanic or equipment operator performs the walk-around for a piece of equipment

at the beginning of his shift, he’s not only checking for routine maintenance purpos-es. The daily walk-around serves a safety purpose as well.

Open belts and pulleys, chains, sprock-ets, and other points of operation must be guarded to prevent the operator or ground personnel from accidentally coming into contact with them. If guards are worn, damaged or missing, the pre-shift walk-around will bring the problem to light.

How about propane tanks and acetylene tanks in the shop? If these cylinders are go-ing to be transported to a job site, they must be chained into place for safe transport. Also check their tags to be sure they’ve been inspected within the past year.

You can even discuss the safety as-pect of the mechanic’s job during weekly meetings. The Monday morning toolbox talk or pre-shift toolbox talk serves a very important function in getting all mem-bers of the crew on the same page as far as communication and job responsibili-ties are concerned. This daily or weekly meeting gives the project manager a set time to share any changes in an ongo-ing job with the entire crew at once, and lets everyone become familiar with com-munication signals and guidelines again. This toolbox talk is an important routine in the safety director’s week as well, so why not let the mechanic and equipment operators know how crucial their walk-around is to their safety?

At the end of each week, review all the jobs that were completed that week and

discuss if there were any safety issues on the projects. Clear up miscommuni-cations and share ways workers can be safer in the future. Remind workers of the walk-around safety inspections; this end-of-week time is perfect for complet-ing walk-arounds and performing main-tenance to bring equipment up to per-fection. Evaluate any accident investiga-tions conducted since the last meeting to determine if the cause of the unsafe conditions were properly identified and properly corrected.

Be sure to document attendance at safety meetings and document the sub-jects discussed. Maintain these records for at least one year. Your insurance com-pany will have an interest in these re-cords as your agent works to keep your premiums low.

Design Drainage from the Base UpBy hAWAii AsphAlt pAVeMent AssOCiAtiOn (hApi)

Figure 1. subsurface drainage example

Proper drainage is important to ensure a high quality, long-lived pavement. Pavement engineers understand that moisture accumulation in any pavement structural layer

can cause problems. In the subgrade and aggregate base layer, it can weaken materials by increasing pore pressure and reducing the materials’ resistance to shear. Additionally, some soils ex-pand when moist, causing differential heaving. We all know what happens when moisture gets into hot mix asphalt (HMA) layers. To prevent moisture such as rainwater, runoff and high ground-water from entering the pavement structure or accumulating in the subgrade, we turn to surface drainage and subsurface drain-age. It is usually more cost-effective to prevent moisture entry and accumulation using surface drainage than to remove it from the subsurface. Let’s look at how to construct both.

Surface DrainageSurface drainage is concerned with removing all water that is present on the pavement surface, shoulder surface or any oth-er surface from which it may flow onto the pavement. If not sys-tematically removed, this water can accumulate underneath and weaken the pavement structure. There are three primary means used to prevent water infiltration and accumulation:• Impermeable HMA. HMA tends to be impermeable below

about8percentairvoids,thereforepropercompactionprac-tices should be followed to ensure an impermeable pavement. Also, minor cracks in the HMA should be sealed.

• Slope.Thepavementsectionshouldbeslopedtoallowrain-water to flow quickly to the edge where it is typically collected in a curb and gutter system or a roadside ditch. A generally ac-ceptedstandardisa2percentcrossslope.

• Grade.Thecurbandgutterorroadsideditchmustbeproperlygraded to allow flow to central collection points such as catch basins or detention ponds. A generally accepted standard is a grade of 0.5 percent or more although lesser grades have been used effectively.

Subsurface DrainageSubsurface drainage is concerned with removing water that per-colates through to, or is contained in, the underlying subgrade. This water, typically the result of a high water table or exception-ally wet weather, can accumulate under the pavement structure by two chief means:• Gravityflow.Waterfromsurroundingareascanbeabsorbed

by the soil, and then flow by gravity to areas underneath the pavement structure. In pavement with high are voids—above 8to9percent—watercanpercolatedownthroughthepave-ment structure itself.

• Capillaryrise.Capillaryriseistheriseinaliquidabovethelev-el of zero pressure due to a net upward force produced by the attraction of the water molecules to a solid surface, such as the soil.Capillaryrisecanbesubstantial—upto20feetormore.

In general, the smaller the soil grain size, the greater the po-tential for capillary rise. Often, capillary rise is a problem in ar-eas of high groundwater tables.

prevent problemsMost pavements have performed adequately without considering these effects; however, HMA pavements can fail if the subgrade deteriorates as a result of excessive moisture or other water-relat-ed problems. These issues can be addressed in two manners:1. Minimize water infiltration into the pavement structure. In

most cases, the accumulated water in the underlying subgrade that causes the damage comes from surface infiltration. This infiltration can be minimized by providing proper roadside drainage and minimizing air voids within the HMA.

2.Providesubsurfacedrainage.Thisneedstobedonejudicious-ly, because it may be somewhat akin to treating the symptom rather than the problem. Subsurface drainage consists of three basic elements (see Figure 1). Those elements appear below.

Element 1. A permeable base to provide for rapid removal of water that enters the pavement structure. Based on research from California, permeable base layers may strip and become clogged with fines thus weakening the overall pavement struc-ture. If unbound, they may also be less stable than a dense-grad-ed aggregate.

Element 2.Amethodof conveying the removedwater awayfrom the pavement structure. At the least, this may consist of a base sloped toward a drainage ditch. At the most, this may con-sist of a pipe collector system.

Element 3. A filter layer (such as a geotextile, graded aggregate layer or ACB*) to prevent the migration of fines into the perme-able base from the subgrade, subbase or shoulder base material. Excess fines in the permeable base will clog its drainage routes and render it ineffective. Depending upon the subgrade and pavement structure a filter layer may not be used.

*ACB = Hot mix asphalt base course of dense-graded HMA primarily used for binder and base courses in Hawaii. The nominal maximum aggregate size is 1 inch; compacted lift thicknesses should be between 2.5 and 6 inches. AC content ranges from 3.8 to 5.7 percent by total weight of mix.

Producers in and around Coolidge, Ariz., know that Western Emul-sions, Inc., in Pinal County began

operationof a$17millionasphalt storageand distribution terminal about five years ago. The company uses the facility to man-age its supply of raw asphalt base stocks for its own emulsion products and has part-nered with paving grade asphalt manufac-turers to manage product distribution.

The effect on Pinal’s economy has been positive. The new terminal provides 50,000 tons of asphalt storage capacity. Western Emulsions footed the $3 million invoice to construct supporting rail spur and switch-ing infrastructure to facilitate the long haul shipment of asphalt via commercial rail. That rail infrastructure has led to addition-al development in Coolidge surrounding the new terminal. Money magazine took noteandrankedPinal#1among25countiesfor job growth and one of the fastest grow-ing in the nation. Employment growth con-tinues there, but let’s zero in on Western Emulsions and what that company is doing for its air quality and bottom line now that capacity is climbing.

To provide heat for the terminal’s as-phalt storage capacity, Western Emulsions installed a terminal heating system that was designed and built by CEI Enterpris-es, Albuquerque, N.M. The system is com-

prised of two 6.3 million BTU/hour hot oil heaters, a 3,000-gallon expansion tank that is shared between them, and the asso-ciated piping, pumps and controls.

The burners on the heaters are designed to use either LP or natural gas fuels. This provides Western Emulsions the flexibil-ity to alternate between fuels to adapt to fluctuating prices and to reduce expenses overall.

John Miller is the terminal manager at Western Emulsions, and said, “Five years into our terminal operation, we’ve found the heating system to be very reliable, and have had no major operational issues with the heaters. We’ve been pleased with the fuel efficiency of the system. The hot oil system works in conjunction with two steam boilers. Fuel costs are spread out among all the units.”

Another factor in reducing fuel expense is to reduce fuel use. That means getting as much efficiency out of the heating sys-tem as you can. With that in mind, CEI engineers designed the Jacketed Firebox hot oil heater with a two-stage heat trans-fer system. In the system, heat transfer oil gains heat from the burner flame as the oil circulates around the firebox and from the burner’s hot exhaust gases via the shell-and-tube heat exchanger that is part of the exhaust system.

Western Emulsions also chose the bolt-in stack heat exchanger for both of their heaters. This places a second heat ex-changer in the exhaust flow of each heat-er, boosting thermal efficiency by another 5 percent. This arrangement transfers as much heat as possible to the heat trans-fer oil, thus reducing the workload on the burner, which in turn reduces fuel use.

According to CEI’s parts and service manager, Stuart Baker, heater emissions are directly affected by burner tuning. This is part of regular maintenance, and involves a qualified technician adjust-ing the burner’s fuel-to-air ratio based on flue gas analysis and ambient temper-ature. Baker describes it like this: “The service technician will insert a flue gas

analyzer into the heater’s exhaust stack. This analyzer will show the precise com-position of the exhaust gas…and in how many parts per million. This information allows the technician to adjust the burner for optimal combustion and the cleanest possible emissions.

“The variable in all this analysis and ad-justment is ambient temperature,” Bak-er added. “Ambient temperature affects

the combustion air going into the burner. That, in turn, affects the content of the emissions. In other words, a burner that is properly tuned on an afternoon when it’s 80 degrees outsidewill performdif-ferently when the ambient temperature drops at night.

“Obviously, it would be cost-prohibitive for a technician to remain onsite and con-tinuously tune the burner day and night, all year long. However, new technology is available that essentially does that very thing.” The new technology Baker refers to is the Fireye Nexus PPC 4000 system, which uses an O2 sensor in the exhauststack to feed flue gas analysis informa-tion in real time to a digital controller.

As the owners, operators and key management personnel of the nation’s asphalt plants and facilities,

you might be wondering why a Washington, D.C.-based advocacy trade association executive is writing a column in AsphaltPro and if it’s even relevant to the work you do.

Considering$85billionisinvestedan-nually in highway and bridge construc-tion by all levels of government, it rep-resents a huge market for the asphalt in-dustry. This fact alone should tell you why spending decisions in the Nation’s Capital have an impact on the livelihood of all employees working in asphalt plant operations.

The federal Highway Trust Fund (HTF) is thesourceof52percentofallhighway and bridge capital investments

made annually by state governments. Unless Congress acts to replenish the fund by May 31, America’s surface trans-portation investment programs will come to a grinding halt. Such a scenario would have a devastating impact on the U.S. economy, the motoring public and everyone involved in the transportation infrastructure community.

The American Road & Transporta-tion Builders Association (ARTBA) and our coalition allies like the National As-phalt Pavement Association are working aggressively to help ensure that Con-gress fixes the ailing HTF and passes a robustly-financed, multi-year highway and transit investment bill. However, in order to create the necessary political pressure, members of Congress need to

hear from the grassroots back home—that means you! As a constituent, you have a power no Washington lobbyist or organization has. You vote…so they will listen to what you have to say.

In the near future, invite your con-gressmen and senators to come to your plant headquarters. When they get there, tell them your story in personal terms.

a Tale of Two additives By sAndy lender

22 April/MAy 2015

Let’s start with the obvious: not all additives do the same thing. Even when injected mid-stream to an asphalt pavement mix to create warm-

mix asphalt (WMA), different additives do different things. They’re not necessarily bringing temperatures down. That’s not what they’re created to do; that’s not what they’re doing. Various additives used to create WMA bind elements or foam asphalt cement, or per-form another chemical or mechanical reaction to effect a change on the behavior of the binder with the aggre-gate. The end result means your plant operator can run the procedure at a lower temperature, and you can real-ize all the benefits thereof.

Focus on two additives in particular. I’ve selected these two based completely on the kind availability of the two companies represented. In alphabetical order:

Evotherm 3GEvotherm® WMA technology from MeadWestvaco Corporation, North Charleston, S.C., is manufactured in Charleston and available around the world to pro-mote adhesion of mix elements. In simple terms, the Evotherm WMA is a liquid that you inject into the binder stream. The Evotherm then creates a chemical reaction between the aggregate and the binder in the asphalt mix. Think of this chemical reaction as forever, all-over attraction that the manufacturer calls “com-paction insurance.”

Ben Bredenkamp explained that Evotherm creates its own chemical reaction in place of the thermal reaction that happens in the typical HMA process. Once Evo-therm is mixed into the binder, either at the terminal or asphalt plant, the plant operator can lower the produc-tion temperature and still see full coating of aggregate because of this chemical reaction.

Among the low-temperature benefits of WMA that plant operators have read repeatedly in this and oth-er publications, Bredenkamp discussed the compac-tion benefits this additive offers. “Evotherm lengthens the compaction window,” he explained. What happens with the liquid additive is a chemical reaction that al-lows the asphalt binder to adhere to the aggregate ful-ly at lower production temperatures than previously used. The lower production temperature equates to a lower paving temperature in the field, which gives the roller operators a longer window to achieve density behind the screed.

FOrTA-FiFORTA-FI represents three fiber reinforcement blends thatForta®Corporation,GroveCity,Pa.,formulatedtoreinforce HMA, WMA and hot/cold patch, respectively. Each of the three products is a proprietary blend that contains aramid and polyolefin fibers of ¾-inch length and other inert materials to provide reinforcement to the asphalt mix. Their purpose is to enhance the cur-rent mix designs.

additives By sAndy lender


At this time, Lane Construction Corpo-ration in Bridgeville, Pa., is a certified pro-ducer of the fiber blends. The fibers have been used on projects in 14 states and 5 other countries. In the test of the fibers at Evergreen Drive at Arizona State Uni-versity, researchers found, “The flexural strength and corrected flexural strength areincreasedby14%and25%respectivelywith the addition of the 1 lb/Ton dosage of the FORTA-FI blend. While various ratios of materials in the FORTA-FI blend were tested to determine the optimum mixture across a wide range of applications, it was determined that the 1 lb/Ton dosage of

the FORTA-FI blend would be best, or op-timum, in terms of flexural properties.”

Another parameter that proved the fi-bers’ mettle in the ASU study was the per-manent deformation testing. From the study’s authors: “Two important char-acteristics were observed for the FOR-TA-FI mixture when compared to the control mixture. One was the endurance of the secondary stage, and the second was gradual/less accumulation of per-manent strain. Both were attributed to the presence of the reinforcing fibers in the mixture, as this behavior is not typi-cally observed in conventional mixtures. The fiber-reinforced mixture had higher

Flow Time values than the control mix-ture(over900%higher),and700%low-er slope values. These indicate that the FORTA-FI mixture has a much higher po-tential to resist permanent deformation than the control mixture.”

This study with other information For-ta Corp has gathered in the field shows a family of fiber-based additives that offer a strengthening property to asphalt mix design. Regional salesman Scott Nazar shared that this property is an ideal offer-ing for those breaking into the Thinlay® market. “It’s a no-brainer,” Nazar said. “The thinner lifts that asphalt profes-sionals are being asked to put down can

herink s.r.o. produced an ACO 11 s 50/70 mix with FOrtA-Fi hMA fibers introduced at a rate of 0.5 kg per ton for the wearing course of the Vaclav havel Airport project in prague. they placed 40 mm on 7,000 square meters for taxiway e and 50 mm on 1,500 square meters of taxiway A. the mix with FOrtA-Fi was also used for repairs on the side of the strips. riGht: scotty’s Contracting created a pG92-28 mix with evotherm 3G to pave the nation-al Corvette Musuem performance track. the racing industry requires a 165 softening point. it’s a highly polymer-modified material.

have this added strength to hold up lon-ger and resist reflective cracking if the let-ting agency doesn’t allow a mill, profile or crack-stabilizing process for the underly-ing pavement beforehand.”

The resistance to cracking that Na-zar mentions was also proved in the ASU study with crack propagation testing. From the study’s authors: “After the re-lationships between crack growth rates as well as slopes of crack growth rates for the 1 lb/Ton dosage of FORTA-FI mixture and the control mixture were developed, it was noted that the fiber-reinforced mixture had higher C* and slope values than the control mixture. This means that

the fiber-reinforced asphalt mixture has a higher potential to resist crack propaga-tion because of the reinforcement effect provided by the reinforcing fibers.”

it’s All About that FWhether we’re discussing cracking po-tential or strength, temperature plays a role in the evaluation of an additive’s ben-efits. How high does a temperature have to go to melt recycled material or how low can a temperature go and still get all the rocks coated with bitumen?

The ASU study authors wrote: “The vis-cosity-temperature susceptibility rela-

tionship at lower temperatures showed no changes from virgin binder, which is positive and desirable, but at high tem-peratures, improved properties were observed to have higher viscosities. The modified binder is far less suscep-tible to viscosity change with increased temperatures...”

With the liquid additive Evotherm functioning as an anti-strip and adhe-sion-promoter, it allows lower produc-tion temperatures for asphalt mixes. That in turn allows longer cooling time behind the screed during which the rolling team can achieve bonus-worthy densities.

Air quality, Bottom line and Capacity overall drive decisions for Western emulsions

Slurry PumP makeS light Work of Drilling muD

“Mud” serves a number of important functions during drilling: it lubricates and cools the drill bit, thereby extending its life; it transports rock fragments, known as cuttings, to the surface; it prevents the wellbore from caving in before the casing is inserted; and it prevents the oil or gas from entering the well before it’s complete. ideally and increasingly, the fluid creating the mud is recycled during drilling. some of the clients of West texas premix pits (Wtpp) needed to recirculate and reuse their drilling mud and tried out the KZn series pumps to do it.

28 April/MAy 2015

According to the U.S. Energy Information Administration (EIA), oil and gas produc-tionintheUnitedStatesinAugust2014was

at its highest volume since 1986. Oilfield rigs areoften located in remote areas. Although the rug-ged terrain may be barren, the site still has to be prepared to accommodate the rig and all of the re-quired equipment, hundreds of feet of pipe, and one or more pits for drilling mud and other fluids. Before drilling can begin, the site must be cleared and leveled and in some cases access roads need to be built. A source of water is also required, which may mean drilling a water well, and one or more pits are dug and lined.

Fluids play an integral role in oil and gas explo-ration and production. When a new well is drilled, some form of fluid is needed. The base of this drill-ing fluid, or mud, can be freshwater or saltwater (brine) or it may be an oil- or synthetic-based liq-uid. The type of fluid and the additives used are de-termined in part based on the composition of the rock being drilled into. Cost and environmental impact are also considerations. The mud may also be modified as drilling progresses and the under-ground environment changes.

Ideally and increasingly, this fluid is recycled during drilling. To facilitate reuse, cuttings are al-lowed to settle out in a pit and the resulting liquid is pumped back to the wellbore.

Water is often a natural byproduct of the drilling and production process. Water may be trapped un-derground along with the oil and gas. Sometimes this produced water is incorporated and used in the drilling process.

This simple overview illustrates the fact that drill-ing a new well is a complicated process with many moving parts. A variety of providers are necessary at different times to deliver their unique services until a well is completed. Not surprisingly, moving all of this liquid requires pumps. United Rentals – Pump Solutions is a large equipment rental provider that helped West Texas Premix Pits (WTPP) of Midland, Texas, with those moving parts.

WTPP manufactures and sells premix pits, trash pumps and safety showers to oil and gas drillers in the Midland-Odessa area. Some of its clients need-ed to pump and recirculate spent drilling mud. Ian Walker, sales representative for United Rentals, rec-ommended BJM Pumps’ KZN series heavy duty sub-mersible pump.

Among other things, WTPP installs and maintains the reserve pits used during oil exploration. The pits areroughly1-acrepondsthatholdfrom2to10feetof drilling fluid that can be from brine or freshwater. The mud coming up out of the hole with the cuttings is deposited into one side of the pit and allowed to settle out, and the fluid that’s reused is pumped out of the other side of the pit. Although using a conven-tional pit configuration, WTPP is trying something new with its pumps. It’s floating the pumps on top of the liquid in the pit. WTPP builds specialized bas-kets to hold the pumps so they’re sitting in just 6 to 8inchesofwater.

“It helps the drilling rig pick up cleaner fluid be-cause the pumps are taking fluid off the top,” Danny Freeman, owner of WTPP said. “As the stuff settles out they have cleaner drilling fluid, and that results in faster drilling.”

WTPP initially rented BJM’s KZN series pumps from United Rental, but after the pumps proved their worth, Freeman decided to buy. “They were great pumps so we stuck with them,” Freeman said.

Although WTPP’s floating configuration has min-imized the pumps’ exposure to solids, the oilfield environment still presents challenges, particularly if the water is brine. “Saltwater is hard on anything,” Freeman said. “I have customers flush the pump on a regular basis to keep it from getting corroded.”

As a result of the success they’ve had with the KZN pumps over the past two years, WTPP now oper-ates 11 of the pumps in various oilfield installations across West Texas.

tough puMpsAlthough not maintenance-free, KZn series pumps are rugged enough to provide long-term operation in harsh drilling environments, including those where the pumps have to handle a great percentage of solids, according to the manufacturer. some of the characteristics that set the KZn series apart from other pumps include:• weAr resistANce: All wetted parts are constructed

of abrasive-resistant 28 percent chrome iron (600 Brinell, 71 rockwell C). in addition, a replaceable hardened wear plate is located on the suction side.

• solids hANdliNg cApAbility: An integral agitator fluidizes settled solids into a slurry, making them easier

to pump with less chance of clogging. the semi-open impeller handles abrasive solid concentrations as high as 70 percent by weight.the KZn series pumps feature Class h motor insulation

and built in amperage ( FlA ) and temperature overload protection; double silicon carbide mechanical seals in a separate oil filled seal chamber; a heavy duty lip seal to provide additional protection for the mechanical seals; stainless steel shaft and shaft sleeve; pump volutes cast from hardened ductile iron (300 Brinell hardness), which is twice as abrasive-resistant as standard ductile iron with walls that are extra thick at the point where pumped slurry enters the discharge.


How to avoid emulsion SoupBy sAndy lender

30 April/MAy 2015

WWith the success of five test sections incorporating comparison tack ma-terials and rates for bonding research

at the National Center for Asphalt Technology (NCAT) Pavement Test Track in Auburn, Ala., contractors are likely to see an uptick in the call for tack between pavement layers. From emulsion-based products you’ll ideally want to spray during daylight hours for best chance of break to trackless tacks that incorporate low penetration asphalt binder, the products available perform their best when shot with best practices. We’ve covered the routine care and maintenance of the tack truck in the Keep It Up department recently; now let’s take a look at the truck’s use in different situations to avoid a tacky mess.

The National Cooperative Highway Research Program (NCHRP) Report 712: Optimization of Tack Coat for HMA Placement suggests that if you have an older, highly oxidized pavement, the sur-face may require a higher rate of tack application. This makes sense. Consider what happens to a 15-year-old asphalt road that’s never seen pre-ventive maintenance. If a community decides to add a protective sealcoat to the pavement, de-pending on the level of oxidation the roadway sucks in that first coat of sealer. A second coat is vital to providing a good seal of microscopic voids. The same holds true when shooting tack for a good bond. You’re not out to make emulsion soup, but you want a coat of material that doesn’t immediately get absorbed, leaving only traces of adhesiveness behind.

The Florida Department of Transportation (FDOT) specifies tack will be sprayed only when ambient temperatures are at 40 degrees F and ris-ing, but it has different rates of application de-pending on the age/oxidation and type of pave-ment to be sprayed. In the state of Florida, you’re more apt to find a pavement made of an open-graded friction course (OGFC) than you are inMinnesota. When the underlying pavement sur-faceisanewlyconstructedOGFC,thetargettackrate is 0.05 gallons per square yard (gal/yd2), give or take 0.01 gal/yd2.Whenit’samilledOGFC,thetargettackrateis0.07gal/yd2.

Not every pavement in Florida is open-graded, so the DOT has other application rate guidelines. For example, if the underlying pavement surface is newly constructed base course, structural course or dense-graded friction course, the target tack rate is 0.03 gal/yd2. If the underlying pavement surface is a milled surface or oxidized and cracked, the target tack rate is 0.06 gal/yd2. The state also recommends a target tack rate of 0.08 gal/yd2 when shooting on a concrete pavement, but this editor’s opinion is that gray mess probably needs to be milled off and replaced.*1

Next look at Michigan (MDOT) specs for tack shooting. Ambient temperatures there must be 60 degrees F and rising, and the rate of application is fairly uniform at 0.05 to 0.15 gal/yd2 for the prod-ucts it approves. The differentiation comes in the guidance for product temperature. For example, MDOTSpecP-603requiresaproducttempof75to 130 degrees for Emulsified Asphalt SS-1h and Emulsified Asphalt CSS-1h; and a product temp of 120to160degreesforCutbackAsphaltRC-70.*2

“Each state has its own spec,” John Ball said. He’s the proprietor of Top Quality Paving, Man-chester, N.H., and regularly consults with contrac-tors to help them get tack coverage right. What he pointed out is not every contractor is follow-ing a state spec for a state job. When you’re work-ing on a commercial or county project, you have to do your own homework and quality control. “You follow the tack manufacturer’s guidelines for am-bient and product temperatures. If the ambient temperature is too cold, the tack coating will cool too fast and the emulsion won’t break. The ground temperature matters.”

What Ball’s referencing is the second law of thermodynamics. The hot tack will transfer its heat to the relatively cooler surface pavement—and to the air above—because it must. It’s the law.

“When we talk about heat transfer, the hotter mass is giving some of its heat to the cooler mass,” Bruce Wilson, O’Fallon, Mo., explained. He’s on the board of the American National Standards In-stitute and wrote the book on Design Dimension-ing and Tolerancing used in college engineering courses around the United States. “We say that the hotter mass is becoming cooler by transferring some of its heat. In a perfect world, the two materi-als would eventually reach the same temperature and be in a state of equilibrium.”

“When it comes to the product temperature, typically you’re looking at 120degrees for emul-sion-based products,” Ball said. “There’s water in these products that has to evaporate off so it be-comes adhesive. For asphalt-based products in a statelikeGeorgia,you’relookingattemperaturesof 400 degrees.”

Your tack truck driver doesn’t have to under-stand the laws of thermodynamics, but he does have to know when his product is ready to spray. Depending on the equipment you use, there will be a number of thermometers located in differ-ent places on the truck and tank. “There’s a dial on the outside of the tank that measures from zero to 300 to give the reading of the inside of the tank,” Ball said. “A glass stick thermometer goes inside through the manhole on top or through a port on the side to measure the material temperature.”

panel on the driver’s side, back of the tank. Brian Horner shared that the Centennial II has a temperature sensor located between the jacketing and the tank. It sends the tem-perature information to the control pan-el where the operator can read it, but what seems more important is the burner con-trols “sense” off the thermometer on the belly. The instructions posted right on the equipment state the operator is not to light the lower burner if the material within the

tank is less than 650 gallons and not to light the upper burner if the material in the tank is less than 900 gallons, no matter what the temperature sensor is reading. Just a quick glance to the large dial on the left side of the back end of the tank will let the operator see how much product he has—it has a range of 64to2,000U.S.gallons.

With temperatures and application rates in mind, there are some basic best practic-es that the authors of the NCHRP Report

712discoveredduringtheirexperiments.Atthis time, many state DOTs have adopted these practices/ideas. Here are some tips to make these ideas work for you.*3

1. Dusty conditions will negatively af-fect your tack adhesion. Clean and sweep the existing pavement surface. The Michigan DOT directs contrac-tors, “Immediately before applying the tack coat, the full width of sur-face to be treated shall be swept with a power broom and/or airblast to re-move all loose dirt and other objec-tionable material.”

2.Water will negatively affect the bond-ing interface. Clean and dry the exist-ing pavement surface. For materials that require dilution with water, Mich-igan DOT spells out its expected prac-tice. “Emulsified asphalt shall be dilut-ed by the addition of water when direct-ed by the Engineer and shall be applied a sufficient time in advance of the pav-er to ensure that all water has evaporat-ed before any of the overlying mixture is placed on the tacked surface.” Buzz Powell of NCAT reminds readers that many states have put a stop to the dilu-tion of emulsified tack.

3. A milled surface provides a better/stron-ger interface than a smooth surface. Con-sider mill-and-fills rather than merely tacking and paving a thin layer on exist-ing surfaces.

4. For the tack products tested in the NCHRP research, each one reached its optimum ISS at a peak temperature, and then began to lose efficiency as the temperature continued to increase. Watch your product’s recommended temperature range(s) and stay within that range during application.

plantsBefore the shows opened, producers could attend the Beyond Compliance: Environ-mental, Health & Safety Conference. It is designed to give companies some help in developing a safety culture in their compa-nies. Asphalt plants and paving crews have unique requirements. The EH&S confer-ence’s purpose each year is to highlight is-sues of concern for the asphalt industry, at both plants and paving sites.

“This is the only conference to focus exclusively on issues related to environ-ment, health, and safety at asphalt plants and paving sites,” Howard Marks said. He’s the vice president for environment, health and safety at the National Asphalt Pavement Association (NAPA). One of the topics discussed at the conference this year was that of safety data sheets for asphalt pavement mix, which will be re-quiredasofJune1,2015.

In the March issue of AsphaltPro, we re-ported that NAPA would provide an SDS template; however, NAPA recently con-cluded that having asphalt pavement mix producers contract with a third party SDS vendor directly would be most credible. NAPA has identified Experien Health Sci-ences, which you can visit at www.expe-rienhealthsciences.com, as one SDS au-thoring vendor that is already familiar with the industry and able to provide an appro-priate SDS for asphalt pavement mix. In addition, NAPA will work with other SDS authoring vendors that your company may already have a relationship with to ensure an accurate and valid product hazard state-ment on the SDS. The cost and time com-mitment to develop an SDS for typical as-phalt pavement mix is negligible, accord-ing to NAPA, and most of the safety sheets will be “warning” of the potential for hot mix to cause burns, etc.

At the Tarmac booth, Ron Heap shared that he’s seen a sort of consolidation of ideas and technologies in the plant side of the industry. From the options for turn-ing the drum to the types of drums, he sees a lot of “consistency” throughout the marketplace.

At the Stansteel booth, a representa-tive shared one of the consistent trends in the industry: adding goodies to the mix. The Stansteel/Hotmix Parts & Service team offers the Accu-Shear® multi-pur-pose blending system to foam liquid as-phalt cement (AC), and can send a vari-ety of additives through. For example, the company offers the AC Modifier Package, which is a skid containing a custom-de-signed injection additive pump with vari-able speed motor, a mass flow meter with a multi-variable transmitter to calculate flow rate, valving arranged for latex injec-tion and calibration, in-line strainer/filter with screen, and electrical starter panel with a variable frequency drive to control the shear/mill speed and variable speed motor controller for the additive pump. Once this AC modifier system completes its job, the modified AC goes through the Accu-Shear. The company also offers Ad-ditive Metering Assemblies to add Evo-therm, antistrip, chemical additives or other items before sending the modified AC to the Accu-Shear.

These and other innovations dotted the tradeshow floor for asphalt and aggre-gate producers, but paving and pavement maintenance contractors had plenty to check out as well.

paving, compactionBomag Americas, Kewanee, Ill., had the TanGO “oszillation” compaction tech-nology with Economizer intelligent compaction (IC) monitoring on display alongside theCR662RMRoadMixpaver/material transfer vehicle (MTV). You’ll be

seeing more of the RoadMix paver and its technology in months to come. Other re-mixing machines were on the tradeshow floor. At the Roadtec booth, the Shuttle Buggy had a new element that you can learn more about in this month’s Here’s How it Works department. It’s the Road-tec Autotracking Package, which helps the paving crew keep the paver and MTV moving at matching speeds.

One of the big focuses at World of As-phalt this year was behind the paver. Both Volvo Equipment and Atlas Copco intro-duced their IC technologies. The two are similar in that they offer readings to the roller operator to help him or her achieve a smooth finished asphalt surface. They differ in the reading that they give and in the way in which they achieve the read-ings, among some other science. Let’s take a look, alphabetically.

Atlas Copco: The new version of the in-telligent compaction system from Atlas Copco uses a global navigation satellite system to track the number of complet-ed passes and a drum-mounted acceler-ometer to measure the surface’s relative

material stiffness. The system gives op-erators immediate materials stiffness re-sults from within the cab to help mini-mize the number of passes. When using the system on asphalt, it also detects the temperature of asphalt to provide con-sistent, relative stiffness readings. In ad-dition, Atlas Copco’s intelligent compac-tion system helps contractors detect any

loose materials so they can perform addi-tional passes to reach the right compaction. Contractors can use the intuitive system on a tablet to set project parameters and view compaction data. Once they achieve the optimal level of compaction, the program alerts the operator. The data storage also means contractors have the results readily available to print off or display for inspec-

tors. The system is available on Atlas Cop-coCC2200throughCC6200asphaltrollersandCA2500throughCA6500soilrollers.

to offering the pass mapping, tem-perature mapping and data storage features of the Volvo IC system, Vol-vo IC with Density Direct includes the industry’s first real-time densi-ty mapping technology. Within the Density Direct system is a calibra-tion screen, where the user sets the target density for the project. Once fully calibrated with data specific to the application, the Volvo Intel-ligent Compaction with Density Di-rect system produces a density cal-culation that is accurate to within 1.5 percent of core sampling, providing a real-time reading of density values over 100 percent of the mat.

With this real-time data, the opera-tor is given the chance to make adjust-ments while asphalt is being paved. Calibrations are also “saved” by the machine, so operators can assign cali-brations to certain elements of a job, and switch back and forth between calibrations to meet the demands of specific job elements. The user in-terface of Volvo IC with Density Di-rect depicts a density map, showing each square foot of rolled asphalt in a color representing density, and also provides a real-time numerical den-sity reading displayed in the corner of the screen. Both Volvo IC and Vol-vo IC with Density Direct offer real-

time temperature and pass mapping data.Usingthe8by10colormonitorof the Volvo IC system, the pass map-ping function captures each compac-tor pass and drum overlap with an in-dividual color, so the operator can see gaps and work to maintain uniform coverage. Temperature mapping pro-vides the operator with a temperature map that shows the path of the com-pactor overlaid with the last recorded surface temperature.

preservationIn the pavement preservation arena, Bergkamp Inc., with headquarters in Salina, Kan., introduced the new

MA30 to apply mastic surface treat-ments. You can read a full descrip-tion of the equipment in this month’s product gallery, but take notice of something interesting here. The MA30 applies the frictional mastic mix of asphalt emulsion, angular fine aggregates, recycled materials, poly-mers and catalysts, which is made to spec. That means fewer calculations for the operator to do.

Something to celebrate in the pave-ment preservation and maintenance arena revolved around the success-ful Silica/Asphalt Milling Machine Partnership. Members of the partner-ship included NAPA, milling machine

manufacturers, labor, academia and the National Institute for Occupational Safe-ty and Health (NIOSH). They worked for 10 years to design, test and implement en-gineering controls for milling machines that effectively reduce potential silica ex-posure below OSHA’s new proposed per-missible exposure limit (PEL).

During the ceremony, Dr. Christine Branche, who is the director of the Of-fice of Construction Safety and Health at NIOSH, spoke on the effects of crys-talline silica exposure and highlighted the recent release of an asphalt mill-ing best practices document to ensure milling machine worker safety. “Some 1.7 million U.S. workers are exposedto respirable crystalline silica in a va-riety of occupations…” Branche said.

The main players from the manufac-turing side of the partnership included Bomag, Caterpillar, Roadtec, Volvo and Wirtgen. The OEMs who will continue to produce half-lane mills will be required to provide water spray systems and vacu-

In a new feature for 2015, AsphaltPro Staff introduces you to the state asphalt pavement association (SAPA) executive directors. This month we share ideas and information from Russell W. Snyder of the merged California Asphalt Pavement Association (CalAPA).

company’s full Name: state Associa-tion: California Asphalt Pavement As-sociation (CalAPA), West Sacramento, Calif.

how long have you been in the asphalt industry? 6 years

Do you have a degree related to the industry? No. BA from Pepperdine Uni-versity, Malibu, Calif.

in what year was your state associa-tion formed? 1953 in Los Angeles, 1994 in Sacramento, merged into one statewide associationin2012.

how many producer and/or contractor members are in your state association? 26producers(somealsodopaving)and39 paving contractor members

What are the top two or three ways you have increased membership in the association? There is a lot of change happening in the asphalt pavement in-dustry, and change is good for associa-tions. The core of our mission is to be a valuable technical and educational re-source for the industry (members and non-members) and agency represen-tatives. Because our state is so mas-sive, deploying that information state-

wide and making it easily accessible is a challenge. We hold two comprehen-sive pavement conferences a year, one in Southern California in the spring and one in Northern California in the fall, plus numerous technical meetings, sem-inars, training classes and other educa-tional opportunities. These events, plus our publications and our on-line pres-ence, disseminate our information far and wide. About a third of our confer-ence and seminar attendees are local agency representatives, and we get many new members after they learn about us through our educational offerings.

What is your favorite method for re-cruiting new asphalt professionals to the industry in general? In concert with oth-ers, we have relationships with several colleges and universities in California

and we sponsor students who are studying engineering or construction management to attend our events free of charge. We also have a scholarship program, and publicize workforcedevelopmentactivitiesofour175member firms.

in what month do you hold your annual meeting? In recent years it has been held in January at the Jonathan Club in Los An-geles.Lt.Gov.GavinNewsom,whohasde-clared his candidacy for governor, was our featured speaker this year.

Do you have a trade show/expo in addi-tion to your annual meeting? We started that as an experiment a couple of years ago as part of our pavement conferences, and it has become enormously popular.

Do you have a staff that assists in pre-paring the annual meeting? Yes. We have a staff of three, plus a part-time technical consultant and occasional temporary help in the office.

Does your office/staff hold educational seminars or webinars for members sepa-rate from the annual meeting/convention(s) throughout the year? Yes, we have a menu of classes we offer as demand dictates, and we move them around to different parts of the state to make them convenient to at-tend. Some of our most popular classes in-clude an introductory “Asphalt Pavement 101,” taught by a former state pavement en-gineer, and “Quality HMA Paving,” taught by a veteran paving contractor. Our class on Caltrans asphalt pavement specifica-tionsweheldaroundthestatein2010and2011waswildlypopular,andwithCaltransspecifications changing again, we are get-ting ready to roll out another version of this class later this year. Caltrans engineers have told me that they have gained a better un-derstanding of their own specification after attending one of our classes.

About how many member asphalt proj-ects do you visit per year/paving season? Perhaps a dozen or so. I wish I had more time to visit more.

About how many member asphalt plant tours do you assist/are you a part of per year? Perhaps 4 to 6 per year, but this is a major emphasis area for us going forward, targeting elected officials, so I expect to be

doing more. It is very rewarding because it is often a very eye-opening experience for our elected representatives, and helps dis-pel many myths that are out there about our industry.

On a scale of 1 to 5 (1 being none at all; 5 being very much), how much of a threat to your members’ marketshare/livelihood is the concrete industry in your state? About half of my members also work in the concrete sector, so I’m going to pass on this question other than to say that the PCC industry is very active in our state. I often say that concrete is an amazing building material and I can’t imagine our world without it. I’m also happy to talk about the many merits of asphalt pave-ments, and let smart engineers make the best choice that suits their needs.

About how many state agency or DOT meetings do you attend per year? Too many to count – maybe 30 or 40. We are very engaged with Caltrans, and since I used to work there, I am comfortable help-ing my members navigate such a large bu-reaucracy(morethan20,000employees),and I think I provide value to Caltrans as well helping them understand our indus-try. Having a strong and productive rela-tionship with Caltrans is in our associa-tion’s strategic plan. I’m pleased that we

are partnering with Caltrans on specifi-cation review, helping improve materials test turnaround times and putting togeth-er a comprehensive joint agency-industry training and certification program for lab technicians. Caltrans gets a fair amount of criticism—I know this first-hand because I used to work there—but they have some truly dedicated people trying to make some important changes for the better, and we are pleased to support the effort.

On a scale of 1 to 5 (1 being none at all; 5 being very much), how much difficulty are your members having in finding quali-fied workers for their asphalt paving or pro-duction crews? This is hard to rate. Cali-fornia was hit harder by the recession than most states, and there was a fair amount of shrinkage in our industry. We seem to be coming back slowly, and I am seeing in-creased hiring activity. I expect we will see a greater emphasis on workforce develop-ment in the months and years ahead.

could you give an example (or two) of a way your state ApA assists members with workforce development? Many of our edu-cational opportunities are tailor-made for companies to help bring less experienced workers up to speed with a rapidly chang-ing industry. Also, I like to tell members that participating on our board and committees

is a leadership development activity—help-ing their employees have a greater under-standing of the industry, the competitive environment, what owners want, and long-term trends. One of my most satisfying ex-periences is seeing younger members par-ticipate, develop leadership skills, and then get promoted in their company. They are more valuable to their companies because of their participation in our association.

On a scale of 1 to 5 (1 being none at all; 5 being very much), how involved are your state elected officials in transportation is-sues such as funding and infrastructure im-provements? Can I go higher than 5? This is mission critical for our industry, and we are pulling out all the stops. We coordinate closely with the National Asphalt Pavement Association and other state asphalt asso-ciations in many activities to educate our elected officials in the importance of trans-portation funding to our economy and our quality of life. We have an outstanding lob-bying firm that represents us in the state-house in Sacramento, and we have an active and engaged Political Action Committee. Meetings with elected officials and candi-dates and plant tours are an important part of our legislative strategy. I’m pleased to re-port that one of our members, Don L. Daley Jr., president of California Commercial As-phalt and also a NAPA member, was recent-ly recognized by NAPA as an “Asphalt Am-bassador” last year for his grass-roots legis-lative activity on the federal and state level.

We also support a pro-transportation funding group, Transportation California, and coordinate our efforts with other like-minded groups, such as the California Alli-ance for Jobs and other construction trade associations. I strongly believe that a fully coordinated and consistent campaign in-volving multiple entities is the best way to make progress in this area. This will also in-clude rallying the support of others outside our comfort zone. Other entities, such as shipping, logistics and agriculture, for ex-ample, have a stake in good roads.

could you share an example of a time when your state ApA hosted elected offi-cials to educate them on the need for high-way funding? Prior to last November’s elec-tions, Jim Syar with Syar Industries in Napa, Calif., conducted a personal tour of Syar’s Lake Harmann facility for Napa County Su-pervisor Bill Dodd, who was running for the state Assembly. I came along to take pic-

tures of what I thought would be a 30-min-ute visit, but it turned out to be about two hours. Bill Dodd was fascinated by not only the asphalt operations, but the quarry and aggregate processing. He won his election, by the way.

Get to know russell Snyder Why (or how) did you join the asphalt in-

dustry? It was partly by accident. My first career was as a journalist, and I worked for United Press International in Los An-geles, Sacramento and Washington, D.C. But when UPI ran into financial difficulty, I took a job as a public information officer for Caltrans in Los Angeles. A few promo-tions later, I was in headquarters in Sac-ramento in charge of policy and adminis-tration. I later worked for the governor’s office and for a time ran all training and apprenticeship programs for the Labor-ers’ Union in Northern California. My first real experience representing the construc-tion industry was when I joined Associated GeneralContractorsofCaliforniaasadis-trictmanagerin2005.Thatgavemeagoodbase of knowledge for when I moved over torepresenttheasphaltindustryin2008.ManyofourmembersarealsoAGCmem-bers. We are very careful to specialize in as-phalt and not to duplicate what others do, and do very well.

What do you see as the most important part of your job as an executive director of a SApA? By far the most important thing we do is to listen to our members, learn from them, so we can represent them effectively.

A close second is for us to gather important information on where the industry is head-ing, and share that with our membership so they can be prepared. Our members are busy putting out fires every day. They count on us to be looking over the horizon, identi-fying threats and opportunities, and sharing that information with them so they can in-corporate it in their business planning. If we are doing our job right, our members should never be surprised by a change in specifica-tion, new regulation or other change that could be costly to their business.

What do you find most enjoyable about your job as an executive director of a SApA? I have an incredible team and I say a quiet prayer of thanks for that every single day. They are highly skilled, professional and motivated, and provide outstanding ser-vice to our members in every way. We also have a very close relationship with some key partners, and also treat them like fam-ily. I often say, “It’s all about the members,” and every member of my team buys into that 100 percent.

What has been the most rewarding ex-perience for you during your time as the ex-ecutive director? Probably helping to fa-cilitate the merger of two regional associa-tionsin2012.Isay“facilitate”becauseitwas really the extraordinary leadership of our members, in particular, John Holliday with Holliday Rock, who managed to put a merger plan together after three previous attemptsfailed,andJeffReedwithGeorgeReed Co.

52 April/MAy 2015

The most productive tools are those that are accurate, easy to use and get the job done quick-

ly. When it comes to road construction projects that time is vital. That’s why hundreds of asphalt rollers and soil com-pactors are packed with features that turn compaction science into a cinch, such as active bouncing control, intelli-gent compaction technology and ergo-nomic operating stations.

While ergonomics might sound like a fluff word used to describe a comfort-able chair or steering wheel, it can have a big impact on the overall job. Ergonomic designs create ideal working conditions and make construction equipment easy to operate, which sets the stage for in-creased productivity. This is why it’s im-

portant to look for ergonomic and time-saving features when purchasing or rent-ing equipment.

Ergonomics is an applied science that considers devices, systems and physical working conditions, and how each re-lates to the capacities and requirements of the worker. In other words, it’s how the operator’s body relates to the ma-chine. When it comes to construction equipment, asphalt and soil rollers are great examples of how ergonomics can have a huge impact on the operator and the project.

These operators are on the machines for 8 to 12 hours per day. If the rollerisn’t designed to allow operators to work comfortably without straining or bend-ing, it could impact the project schedule

and will eventually take a toll on the op-erator’s body.

Ergonomic designs reduce the time that operators spend in fatigue-gener-ating positions, such as leaning to get a good view of drums. To do that, man-ufacturers must consider how opera-tors maneuver their bodies to adapt to changing work conditions. Success-ful solutions create a safe environment and keep the operator comfortable. And a comfortable operator is a productive operator.

There are many features you can find on rollers that contribute to ergonomics, including rotating seats, built-in con-trols, vibration switches, sound damp-ening engines and heat gauges. And they all add up to greater efficiency.

ergonomics Increases productivity, Safety


Taking StageAn operator needs to have superior visi-bility of the equipment and worksite, not only for safety reasons but also for pro-ductivity. If the operator doesn’t have a clear view of the drum edge he must rely on his best guess or someone else for guidance. This not only increases the risk of damaging curbs or other obsta-cles, but also consumes time. One way to ensure clear sightlines to the drum edge is a moveable seat, rather than a stationary seat. A moveable seat can ad-just with the operator, which increases visibility without making him or her lean or twist the body. Some rollers even fea-ture 180-degree spinning seats tomakelooking to the front and back of the ma-chine easier. Sideways sliding seats also allow the operator to comfortably move from one side of the roller to the other to maintain optimal visibility and avoid having to strain his or her neck to get a clear view of the drum edge. It also gives operators the confidence to work faster.

Having a clear view around the ma-chine is just as crucial for the safety of nearby workers.

in controlAlong with seat positioning, ergonom-ics also pertains to the controls. In fact, the industry has mandated requirements on ergonomics and the placement of switches and buttons. Designs are based strictly on helping the operator focus on the rolling process rather than looking down at the console. When controls are in the optimal position, operators can quickly and comfortably move from one switch or button to the next, making the process more fluid. It doesn’t seem like much, but over time it can help increase production.

Controls also should be grouped based on function for optimal operator efficiency and familiarity across multi-ple pieces of equipment. Manufacturers that make several pieces of equipment that are similar to one another – such as soil rollers and asphalt rollers – usually position controls consistently across all the machines. This saves operators time from familiarizing themselves with the controls. Not only should controls be easy to use and identify, but also catego-rized together for even greater efficien-cy, such as propel functions, vibratory

functions, water controls and auxiliary functions.

To provide maximum equipment con-trol for operators, some manufacturers attach controls directly on the right side of the operator seat. This provides unin-terrupted access to controls, even when the operator is rotating the seat for bet-ter visibility.

Knowing how the roller is operating is critical to superior compaction and avoiding unexpected downtime. A roll-er’s display should clearly indicate vital operating parameters, such as ground speed, vibration frequency, fuel level and coolant temperature. It also should alert operators to malfunctions or improper usage as well as diagnostic codes and ser-vice intervals.

Finally, all controls, symbols, warn-ings, gauges and instrument panels should be easy to read. The standard use of ISO symbols or registered universal symbols on panels and controls helps any operator react to changing condi-tions despite possible language barriers.

Unwavering StabilityThe whole basis of how asphalt and soil rollers work not only comes from their weight and size, but most importantly their vibrations. While this makes the compaction process more efficient it can have the opposite effect on operators. Over time vibrations generally make it uncomfortable for operators to grip the roller’s controls, which can impact pro-ductivity. Look for models that allow operators to toggle drum vibrations on or off when they’re not needed. Some manufacturers reduce vibrations by in-corporating extra insulation through-out the roller. Keep in mind that rubber compound materials will significantly absorb and reduce vibrational impact on the operator. That’s why some man-ufacturers place a series of rubber shock mounts between the drum and frame, as well as underneath the platform or cab. Andonsome25-tonstaticrollers,oper-ator cabins sit on compressed airbags – sometimes called floating cabins – which do wonders to minimize vibrations and boost operator comfort.

A Sound choiceLoud diesel engines and handheld tools make communicating with crew mem-bers a challenge on construction sites. When an operator can’t communicate with other crew members and visa versa, they could be missing out on vital infor-mation that can impact jobsite efficien-cy and safety. To help minimize noise and promote easy communication, look for rollers with cabs that reduce outside noisetolessthan80decibels,whichisasquiet as a dishwasher. They allow the op-erator to easily communicate with crews using a walkie-talkie or hand signals. And minimal engine noise lessens the risk of hearing damage for the operator.

Diesel engines and handheld tools aren’t the only source of noise – large hy-draulic pumps used for a roller’s drive or vibration functions also can contribute. Some manufacturers minimize noise by optimizing the vibration characteristics of hydraulic pumps with respect to the engine. This design allows manufactur-ers to continue using powerful engines while significantly reducing the noise.

Going the Extra MileOther timesaving features can make all the difference for the roller operator. For example, when compacting asphalt, it’s common to have a second person with a heat gun periodically checking the as-phalt temperature. But a heat gauge in-corporated right into the roller can do the job while saving time and labor costs of a second person. And it is less fatigu-ing because it eliminates the need to mount and dismount the roller if the op-erator is doing the checks herself.

it’s in the DetailsDissecting asphalt and soil rollers pro-vides solid examples of what to look for in terms of ergonomics on a machine. Each piece of equipment comes with a whole new world of features to select, because not all machines are created equal. While some of them seem minor and tedious, consider the advancements in productivity and safety they create. Suddenly a few simple features, or a higher quality machine, seem like some-thing that should be a priority.

Paving and Pavement Maintenance EssentialsWith the spring paving season

upon most of us, AsphaltPro con-tinues a unique-to-us method

for examining the equipment, products and services available in the asphalt profession-al’s marketplace. Of course we still focus on the items relevant to an asphalt business, but we have a new approach to make the fo-cus more useful to you each month.

Notice this month that all equipment and services listed in the product gallery relate to the paving side of the industry. From the in-formation we receive and solicit from OEMs and consultants, we’ve selected just the bits that pertain to laying and compacting a gor-geous asphalt mat, or maintaining and pre-

serving any pavement surface, or profiling and testing the road for perfect quality as-surance. When you see the Paving and Pave-ment Maintenance Essentials headline for our product gallery, you’ll know you have the latest and greatest in the paving/preser-vation/testing side of the asphalt game.

AtlAs lAuNches icAs mentioned in the World of Asphalt wrap-up, Atlas Copco, Commerce City, Colo., launched its intelligent compaction (IC) system, which is designed to give con-tractors real-time material stiffness read-ings during soil and asphalt rolling. The system features a touch screen at the op-

erator’s station. The IC system from At-las Copco uses a global navigation satellite system to track the number of completed passes and a drum-mounted accelerome-ter to measure the surface’s relative mate-rial stiffness. The system then gives opera-tors immediate materials stiffness results from within the cab to help minimize the number of passes. When using the system on asphalt, it also detects the temperature of asphalt to provide consistent, relative stiffness readings. In addition, Atlas Cop-co states the IC system helps contractors detect any loose materials so they can per-form additional passes to reach the right compaction.

the new Atlas Copco iC system is available on CC2200 through CC6200 (the latter is pictured here) asphalt rollers to simplify compaction using real-time data to alert the operator when material stiffness has been reached.

Contractors can use the intuitive system on a tablet to set project parameters and view compaction data. Once they achieve the optimal level of compaction, the pro-gram alerts the operator, so he or she can stop and reduce the risk of over-compac-tion. The data storage also means contrac-tors have the results available to print or display for DOT inspections.

VolVo lAuNches ddAs mentioned in the World of Asphalt wrap-up, Volvo Construction Equipment, Shippensburg, Pa., launched its intelligent compaction (IC) system with Density Di-rect, which is designed to give contractors real-time density mapping during asphalt rolling. Dr. Fares Beainy, research engineer at Volvo said, “With Density Direct, opera-

tors have real-time access to the metric that ultimately determines the success of their work, density.”

Within the Density Direct system from Volvo is a calibration screen where the user sets the target density for the project. Once fully calibrated with data specific to the ap-plication, the system produces a density calculation that the manufacturer states is accurate to within 1.5 percent of core sam-pling. The machine “saves” the calibration settings so operators can assign calibrations to certain elements of a job, and switch back and forth between settings as needed.

The user interface of Volvo IC with Den-sity Direct depicts a density map showing each square foot of rolled asphalt in a col-or representing density and provides a real-time numerical density reading displayed in thecornerof thescreen.Usingthe8by10color monitor of the system, the pass map-ping function captures each compactor pass

and drum overlap with an individual col-or so the operator can see gaps and work to maintain uniform coverage. Temperature mapping provides the operator with a tem-perature “map” that shows the path of the compactor overlaid with the last recorded surface temperature. The system’s inter-nal 14GB hard drive stores the data gath-ered from pass mapping, temperature map-ping and density mapping. The system will beavailableinthefourthquarterof2015onnew Volvo asphalt compactors.

BErGkAMp FillS SOME holesBergkamp Inc., based in Salina, Kan., has in-troduced the MA30 Frictional Mastic Sur-face Treatment Applicator, which applies a material mix that is made to spec. The full-length ribbon mixer works to maintain the material consistency. The material is then applied through a patent-pending, vari-able-width, low-pressure spray bar.

The MA30 features a steel 3,000-gallon material tank, which contains the hydrau-lically driven, full-sweep ribbon mixer. In-cab controls let the driver operate all sys-tems, including the mixer start/stop/re-verse and spray bar start/stop, height and width, side-shift and individual nozzle con-trols. The application is computer-con-trolled with an onboard system that con-tinuously varies the pump rate based on the truck speed and spray width. Easy-ac-cess mastic strainers protect the pump and spray nozzles from clogging and potential damage by aggregates and solid material.

The manufacturer also offers the all-in-one FP5 flameless pothole patcher, which is designed to reduce material waste. It features an insulated 5.1-cubic-yard, elec-tric-heated hopper that keeps asphalt at a constant temperature, and comes stan-dard with the InPave® technology pothole patching management system to moni-tor and manage pothole patching perfor-mance. The technology provides a way to monitor production, performance and lo-cation of each pothole patcher and crew with multiple data reporting sensors stra-tegically placed throughout the FP5. As the operator repairs potholes, the InPave technology automatically gathers the data and transmits it back to the office. The web-based technology allows data retriev-al from any computer with Internat access.

To repair a pothole with the FP5, first re-move and square off the damaged area us-ing the pavement breaker. Second, use the air-driven air and tack wand to blow out any remaining debris, and to apply the tack coating, which is kept warm in its tank us-ing an indirect electric-heating band. Third, use the material chute to deliver the hot as-phalt to the prepared area. The standard 140-degree chute can be locked at different height angles and in 15-degree side-to-side increments. The optional swing-auger sys-tem gives more flexibility in pothole repair, delivering asphalt in a wider arc that rang-es from the driver-side wheel track past the passenger-side wheel track. Finally, the

compactor consolidates the material even-ly with the existing pavement.

The truck-mounted unit’s electric-heat system uses an onboard hydraulic-pow-ered AC generator to warm the full-length, electric heating elements. These elements are designed to produce consistent materi-al heating throughout the hopper and elim-inate hot spots. The thermostat allows the temperature to be set to match the mate-rial being transported. The system can be plugged into an external power source to keep material at the proper temperature overnight or over a weekend.

For more information, contact Bergkamp at (785) 825-1375 or [email protected].

MOTOrBOOkS rElEASES cATErpillAr pr MASTErpiEcEBy sandy lender

the newly released hardcover coffee table book from Motorbooks/Quarto publishing Group usA inc., a licensee of Caterpillar inc., gives a decades-long look at Cat heavy equipment’s evolution. While the author and senior editor of Construction equipment magazine Frank raczon obviously gives the readers what they want with info about Cat machines, he truly offers a great history lesson as well, complete with some help from the historical Construction equipment Association, Bowling Green, Ohio. did you know the Caterpillar yellow used to be gray with a gorgeous creaminess to it?

Beyond color changes and when Cat bought Bucyrus international, the book gives a timeline for the introduction of diesel engines, when cabs for operators came into vogue to keep dirt and debris from rocketing in to hit the drivers, and when rOps became the buzzword.

the chapters cover track-type tractors, motor graders and pull graders, wheel tractor-scrapers and towed scrapers, wheel loaders and track loaders, hydraulic excavators (crawled and wheeled), dump trucks, backhoe loaders (and skid steers), and surface mining machines.

the big, gaping hole in the 224 pages of Modern earthmoving Marvels is the paving equipment. now, to be fair, pavers and rollers don’t technically move earth. neither do plate compactors or hydraulic hammers/concrete breakers, which do get coverage. But i don’t intend to nitpick the lack of paving equipment in an earthmoving book. the book is awesome overall in its level of research and selection of huge, colorful images.

Anyone who has grown up in the construction industry will want a collector’s copy of this book for the coffee table or the headquarters lobby. then you’ll want a copy that you can leaf through, read, consume, and then go through again because you want to re-read and re-see all the memories of how far modern man has come.

For more information, you can check out the book at amazon.com.

here's how it works

The paver operator uses the paver pendant to turn the system on or off, and to adjust the conveyor left or right.

Step 1

The autotracking sensor measures distance from the hopper target to the shuttle buggy.

Step 2

The two towers on the paver’s platform indicate when the shuttle buggy is slowing, increasing speed or maintaining current speed.

Step 4

Then it sends the information to the shuttle buggy operator to signal whether the equipment needs to slow down, speed up or maintain its speed to keep a steady pace with the paver.

Step 3

Roadtec’s Autotracking PackageTo decrease the number of machines

each operator has to track, and to provide even operation of those ma-

chines, the engineering team at Roadtec, Chattanooga, developed the new Shuttle Buggy Autotracking Package. It uses wire-less technology to get smooth material transfer while the paver sets a pace that the MTV matches. Here’s how it works:

First, the paver operator turns the sys-tem on or off by pressing a button on the paver pendant at his platform. This sends a wireless signal to the autotracking sen-sor, which is mounted or hung near the discharge chute of the material transfer vehicle (MTV) and the paver.

The autotracking sensor is mounted aboard the C3 conveyor and monitors

the distance to the hopper target. (An op-tional, second sensor can monitor the pile height within the hopper.) The hopper should be fixed with a smooth, flat sur-face for the sensor to use as a reference point to send and receive distance sig-nals. If you don’t have a flat surface, weld a small piece of metal to the hopper’s ex-terior. As the autotracking sensor mon-itors distance, it zings a wireless signal to the shuttle buggy operator to let him know that the equipment’s speed is—or is not—matching that of the paver.

If the MTV needs to slow down, the au-totracking sensor provides that informa-tion to the operator. The amber and red lights at the top portion of the two cylin-drical towers on the paver operator’s sta-

tion will light up to indicate the shuttle buggy is slowing down. If the shuttle bug-gy needs to speed up, the amber and red lights at the bottom portion of the two cy-lindrical towers will light up to indicate the increase in speed. When the green lights in the center of the towers are illu-minated, the operators can rest assured that the shuttle buggy is at an acceptable distance from the paver—moving at the same speed.

If the operator needs to adjust the dis-charge conveyor to hit the hopper target, he can press the appropriate button on the paver pendant to signal the conveyor to move to the right or left.
