Test Study on Overdose Cement Stabilized Crushed Rock Base

The early disease of semi-rigid asphalt pavement disease will seriously affect the quality and durability of road usage and the life of the road. Water into the pavement layer cause water content increases and the strength greatly reduced in primary or sub-base material which contends more soil and greater soil plasticity index. Resulting in premature failure of asphalt pavement, and the road surface rutting greater is the insufficient primary strength. The use of water overdose primary stability can fully play its high strength and low cost advantages, but also has a low shrinkage, minimize shrinkage cracks.
