摘要：在對組成水泥穩定碎石混合料的各檔集料組成比例、毛體積密度和吸水率的基礎上，采用了瀝青混合料中集料的比表面積系數，建立了混合料的最佳含水率和最大干密度與這些參數的關系，并通過試驗驗證了公式的可靠性，從試驗過程上分析了存在的問題與不足，進而為水泥穩定碎石生產和施工建立了指導依據。

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.
