HINT: Good construction practices give longer lasting surfaces


5.) CURING.A 24 hours curing periods allows for good cohesion between the soil particles


5.) CURING

POST CURINGIf the surface is to be paved with either Bitumen or concrete, a surface drying of 3-4 days is advisableIf surface is not to be sealed, i.e. rural roads (unpaved) is to be made, some gravel fines are to be added to the surface to aid vehicles gain traction in wet conditions.

B O R O Y M E R DZ-1X(Recommendation of tests for earthen roads to be conducted after DZ-1X application):Step 1.Before road construction: A. Average plasticity index of soil: helps determine moisture content needed to attain maximum dry density (MDD).B.Optimal moisture content(OMC) to reach MDD.C.Laboratory MDD of soil.D.Laboratory CBR.E.If required: enzyme modified MDD of soil and PI.

Step 2.At time of construction: F. Average moisture of soil on site, needed to offset the quantity of water that will need to reach OMC.G.Field soil density of soil helps determine quantity soil required to finish compacted road.

Step 3.Post construction: H. Approximately 24 hours later MDD analysis by sand replacement method or BS Core Cutter Method. I. CBR of soil after 7 days, field analysis by Dynamic Cone Penetration, lab analysis of undisturbed sample (as per IS-2720). J. CBR of soil after 30 days, field analysis by Dynamic Cone Penetration, lab analysis of undisturbed sample (as per IS-2720).

Note: Light traffic is to be allowed after 3 hours of compaction, heavy (loaded) vehicles to be allowed after 48 hours.If there is a moisture problem, allow to evaporate then allow vehicles.


Application Notes:- Day 1:Plan project with supervisory personnel.Assemble all required Equipment.Make equipment maintenance checks.Verify fuel supply.Verify and make arrangements for water and water supply.Verify BOROYMER DZ-1X supply.Meet with operator personnel and discuss procedure.If new soil is required, it should be brought in and put in place.Road barriers should be assembled and checked.Traffic diversion plan should be finalized.Traffic control personnel should be instructed according to the work plan.Instructions should be given in case of rain.Security for equipment should be arranged.Contingency plans should be made in case of equipment break down or problems.


Application Notes:- Day 2:Mix BOROYMER DZ-1X with water in water truckBreak up soil with rippers on grader.Remove or crush large BOROYMER DZ-1X in Water.Cut shoulders with grader on each side of road first.Mix soil with grader and (add aggregate if necessary).Moisten soil with water truck spray bar.Mix soil with grader blade from each side to the other.Repeat #5 #6 all day. Wind row with grader blade on each side of road.Let wind row aerate over night.


Application Notes:- Day 3:Moisten wind row soil with water truck spray bar.Moisten soil in front of grader.Grader blade 2 lifts/layer from wind row.Sheeps foot compactor follow grader blade.Drum Compactor with vibrator on follows Sheeps foot compactor.Repeat #1 through #4 for 3/4 of expected depth or wind row.Continue to moisten wind row.Continue to use grader to blade 2 lifts.Continue to use Drum compactor with vibrator off.Repeat #6 - #8 for last 1/4 of expected depth.Moisten surface in front of Pneumatic roller.Use Pneumatic compaction for smoothing final finish.

Allow to set for 3 5 Days with no traffic use. Traffic use too soon will cause rutting.


Using Enzymes in soil stabilizationTerms Used in Road Construction

Terms Used in Road Construction

Go Green With Bio-EnzymesThe Challenge faced when dealing with site Engineers:Existing pavement design methods cater to relatively high volumes of traffic with damaging effect quantified in terms of ESA (equivalent standard axles). In contrast, main factors controlling deterioration of LVRs (Low Volume Roads) are dominated by the local road environment and details of design (drainage), construction and maintenance practice.Conventional specs apply to ideal materialsStandard methods of test do not always give a true assessment of performance of local materials

Go Green With Bio-EnzymesPrimary Problem faced: The art of the roads engineer consists for a good part in utilizing specifications that will make possible the use of materials he finds in the vicinity of the road works. Unfortunately, force of habit, inadequate specifications and lack of initiative have suppressed the use of local materials and innovative construction technologiesConsider materials fitness for purposeMake specification fit materials rather than materials fit specification (resource based specs)

Pavement Performance:

Selection of material for construction:Material strength derived from combination of:- Cohesive effects- Soil suction- Physio-chemical (stab) forces- Inter-particle frictionMaterial selection influenced by:- Traffic loading- Environment- Material properties (plastic mod)- Pavement configuration


Wide variety of chemical additives available including:Wetting agents to improve compactionHygroscopic salts (e.g. calcium, magnesium or sodiumchlorides)Natural polymers (e.g. ligno sulphonates)Synthetic polymer emulsions (e.g. acrylates)Modified waxesSulphonated oilsBiological enzymes

Go Green With Bio-EnzymesThe Economics of using BOROYMER DZ-1X:Road stabilization with BOROYMER DZ-1X offers significant economic alternatives to standard road designs.

Note that design strength has been maintained while costs have been significantly reduced.

The Economics of using BOROYMER DZ-1X:

Enamel seal coat Grit asphalt mixRubble-soil mixCONVENTIONAL METHOD: STRUCTURAL STRENGHT IS MAINTAINED AT100% COSTBox-Cut required

Alternative# 1Maintains the standard design strength while reducing or eliminating costly materials through stabilization of local materials or economical material blends for typical cost reductions of 20% - 30%. Laboratory verification of soil blends can be performed before project execution

ENZYME TREATMENT: STRUCTURAL STRENGHT IS MAINTAINED REDUCING THE COST BY 20-30%BOROYMER DZ-1X TREATED SUB-BASE, WITH SAME DEPTH OF STANDARD SUB-BASEBox-Cut Not required

Alternative# 2Improves the standard design through stabilization of available materials blended to optimize gradation and plasticity. The result is a maximum increase in stabilized strength. Note that savings of 40% are possible by thinking outside of the standard design and road materials. Cost comparisons to matching structural upgrades using traditional materials and designs generally favor stabilization.These same alternatives can be used for other surface coatings such as RCC, or Tar based seal coats.
