Study on Mix Design of Cement Stabilized Materials for Airport Pavement Base and Mix Ratio Control in Construction

摘要: 以某机场机坪工程为基础，通过试验选定机场道面基层水泥稳定材料原材料，采用击实方法确定水泥稳定材料的最大干密度、最佳含水率。试验表明：4.5%的水泥剂量，实际施工配合比为水泥:大碎石:小碎石:石屑:水=108.0:544.3:762.0:870.8:120.6 = 1:5.0:7.1:8.1:1.1的水泥稳定材料经济合理的满足道面基层施工要求，并且探讨了施工中的配合比控制。

Abstract: Based on the apron engineering of an airport, the raw materials for the cement stabilized materials of the airport pavement base were selected through tests, and the maximum dry density and optimum moisture content of the cement stabilized materials were determined by the compaction method. The test results show that the materials of cement, large crushed stone, small stone, stone chips, water and the corresponding ratio of 1:5.0:7.1:8.1:1.1 and 4.5% of cement dosage economi-cally and reasonably satisfy the requirements for the actual construction of airport pavement base. Finally, this paper discusses the control of the mix ratio of cement stabilized materials in the construction.
