1. A motor grader is use to loose soil surface to the required depth of 150 mm. This can be achieved by using the ripping teeth of the motor grader.
2. Then a rotorvator (driven by a tractor) is use to scarify the loosen soil for a better mix.
3. Apply the BP2G solution on the already loosen soil. BP2G should be mixed with water at a required proportion in a water tank. The solution is then spray on the soil by gravity.
4. Again the rotorvator is use to mix BP2G and the soil to achieve even moisture content. The rotorvator should follow behind the water tank.
5. Repeat the process for 3 to 4 passes. This would bring the mixed material of BP2G and the soil to the optimum moisture content state.
6. Use the motor grader to form camber to provide proper drainage of water along side of the road. The gradient is approximately 1:20
7. The treated soil is then compacted with a 10 tons vibrating compactor.
8. Curing should be carried out the next day by spraying plain water (if required) and followed by a few passes of compaction.
9. Applying the BP3G using a spray pump to the treated road surface for better control on wear and dusts. Usually BP3G is applied 1 or 2 days after the road base has been treated depending on the weather conditions.
10. Sand or quarry dust or chipping or pre-mixed would then be laid on top of the BP3G layer immediately after spraying the sealant.
