Ride Quality
Many improvements have occurred in recent years to allow asphalt to be even smoother. Milestone has invested in the latest Pavers and Material Transfer Devices to achieve the smoothest pavements
Asphalt Pavements are Smooth
The ability to paveuninterrupted and the absence of joints every 20 feetresult in SMOOTHpavements

Sheldon G. Hayes Award Winner
Smooth pavements, such as the recent Sheldon G. Hayes award winner last longer, are safe, save gasoline, decrease wear and tear on vehicles and are enjoyable to drive. Milestone is a two time winner of this most coveted national award !

Asphalt Pavements Are Safe
Inherently, some aggregates offer better skid resistance over a longer period of time. Asphalt pavements allow the specifying agency to choose a skid resistant aggregate based on traffic volume. Milestone has conducted extensive studies on friction.

Milestone Pavement Friction Research
• Wet Friction on Pavements are related to both Macro and Micro Texture of the Pavement
• Friction can be maintained at a higher level long term if these parameters are controlled
• Pavements which utilize Steel Slag are higher in both parameters than conventional pavements
Safe
• Milestones research found that asphalt pavements can be designed at any level of friction desirable to the application. This research also found that friction can also be maintained over long periods of time and under varying traffic conditions.
Steel Slag Aggregate
• Pavements which contain Steel Slag Aggregates can save lives due to increased wet friction
• Steel Slag also improves rutting resistance and increases the durability of the pavement
• Steel Slag is being used on our highest performance pavements in Indiana
• Milestone is a leader in placement of these pavements

A review of Ohio’s Interstate compared asphalt and pcc pavements ranging in age from 25 to 34 years old. The asphalt pavements were lower in initial costs with an ever widening gap throughout the life of the pavement.
An important note is the asphalt pavements have provided 25 to 34 years of service without the need for reconstruction or rehabilitation. Only routine maintenance of the wearing course.
Asphalt Pavements are Durable
Ohio Compares HMA and PCC
“Clearly, the majority of the AC overlays included in the LTPP database have served for 15 years or more before the load related and non-load-related distresses became sufficient to require rehabilitation.”

States have more HMA contractors than pcc contractors thus money spent on HMA pavements are more likely to remain in the local economy.

User Delay
• As traffic reaches road capacity any disruption creates huge delays on roads
• The US is starting to calculate user delay fees into road projects to speed construction of any rehabilitation
• Night Paving has become popular to minimize peak traffic during daytime use
• Mill and Fill has proven on a Life Cycle basis to minimize user delays

Warranties• Milestone is a leader in warranted
pavements. Milestone built the first INDOT 5 year warranted pavement in 1996 on I-70 east of Greenfield, Indiana
• Milestone is also warranting other public and private work. If you are interested ask about the warranties option.
Shhhhh!
Asphalt Pavements are Quiet
NCHRP 268
Conclusions: “In general, when dense-gradedasphalt and PCC pavements are compared,the dense-graded is quieter by 2 to 3 dB(A)”
A 3dB(A) reduction corresponds to:- doubling the distance (line source)- reducing the traffic volume by 50%- reducing the traffic speed by 25%
“Where traffic noise is just loud enough to justifybuilding noise barriers to protect adjoining homes and businesses, the substitution of a Porous Asphalt wearing course can reduce the noise to an acceptable level. The cost is about 1/8 of a noise barrier on one side of the highway, or 1/16 on both sides of the highway. Not only does this technique save tax dollars, but the road is environmentally and aesthetically superior.”
Roads & Bridges – Jan. 1989
Porous Asphalt
• Milestone is building projects additional projects with Porous Asphalt to reduce tire noise. These pavements are proven to be 3-5 decibels lower in studies.

California has been specifying asphalt liners for water containment facilities since the 1950s
After 18 months in the asphalt-lined pond the salmon are released. In Oregon they have “had good results rearing quality fish in the asphalt-lined ponds”

Recycling is unique to asphalt pavements.
• Results in an economic savings• Conserves natural resources:
- energy- aggregate- asphalt cement
100% Recyclable
Reclaimed Asphalt Pavements (RAP)
• Milestone Contractors was a pioneer in reclaiming asphalt pavements in 1978
• The process involves milling off the old asphalt layer
• Processing the RAP into useable size• Recycling through the hot mix plant• Currently Milestone recycles 400,000 tons/year

Rubblization Technology
• Milestone investigated a number of rehabilitation technologies for concrete pavements which include…
• Remove and replace• Joint repair• Crack and Seat• Rubblization

Rubblization Technology
• Rubblization Technology has been determined to be the best rehabilitation technology for worn out concrete from a life cycle cost analysis for many concrete pavements
Rubblization
• Studies have found that rubblized concrete is structurally higher than granular base due to the keyed structure of the concrete
• The rubblized concrete is primed with asphalt emulsion
• Then overlayed with HMA

• 5 Years, $150 million• asphalt ($50 million)• cement and concrete• long term pavement performance• pavement effectiveness• bridge protection• snow and ice control

• Cold Weather Cracking Prediction
Our Technology for Roads
• Mix DesignCombining Asphalt and Aggregate into an optimum blend
Subgrade
• Subgrade needs to be considered in all projects• Building roads in Florida ( Sand ) vs Georgia (
Red Clay ) are very different– Lime treatment works with some clays not all– Cement treatment almost always works but has
had significant problems due to too much cement causing cracking in upper layers
– Granular bases are used often in some areas
