控制水泥剂量 提高水泥稳定碎石基层的抗裂性能

The Study on the Improving the Crack Resistance of Cement Stabilized Gravel Base by Controlling the Cement Dosage

通过对优化水泥稳定碎石集料的矿料级配、采用表面振动压实法进行基层配合比设计、采用试验路确定的最佳含水量和最大干密度进行配合比设计、提高生产质量控制水平,对控制水泥用量和矿料级配的均匀性进行分析,总结了选用合理、较低水泥剂量的方法,阐述了降低水泥稳定碎石基层的设计水泥剂量是提高基层抗裂性能、降低工程投资的有效途径。

Based on the mineral grading of cement stabilized gravel aggregate,the optimum water content and the maximum dry density of mixture ratio design as background,this paper analyzed that the cement dosage of reducing cement stabilized gravel base was the effective way to improve the crack resistance and reduce the engineering investment.
