水泥稳定碎石基层混合料的优化设计

Optimization Design of Cement Stabilized Crushed Stone Mixture

针对目前施工技术规范中的水泥稳定碎石混合料设计方法与现场施工情况相脱节的现象,总结了现行配合比设计中存在的问题,根据研究成果和工程实践,对水泥稳定混合料的级配范围、最大干密度取值进行比较研究,提出了优化措施,并在试验路工程中得到了较好的验证。

According to the difference between the current design method in specification and on site construction of cement stabilized crushed stone mixture,this paper analyses it＇s gradation band and maximum dry density and puts forward some optimization methods.The methods are also testified in test road.
