摘要：在对组成水泥稳定碎石混合料的各档集料组成比例、毛体积密度和吸水率的基础上，采用了沥青混合料中集料的比表面积系数，建立了混合料的最佳含水率和最大干密度与这些参数的关系，并通过试验验证了公式的可靠性，从试验过程上分析了存在的问题与不足，进而为水泥稳定碎石生产和施工建立了指导依据。

Abstract： Based on the ratio of aggregate composition， bulk density and water absorption of cement stabilized crushed stone mixture， the specific surface area coefficient of aggregates in asphalt mixture was used to establish the best water content and maximum dry density and the relationship between these parameters， and the reliability of the formula was verified through test. The existing problems and shortcomings were analyzed from the test process， which establishes a guidance basis for the production and construction of cement stabilized gravel.
