水泥稳定碎石基层的最低劈裂强度和抗压强度

Minimum Splitting and Compressive Strength of Cement-Treated Aggregate

摘要:

根据水泥稳定碎石混合料的室内试验结果及其在路面结构和施工阶段的受力状况分析,提出了水泥稳定碎石基层的最低劈裂强度和抗压强度建议标准.经试验验证,根据该标准所确定的水泥稳定碎石基层的级配组成、强度均符合要求,且收缩量小,致使其收缩裂缝减少,沥青面层的反射裂缝也相应减少.

Abstract:

Standard for minimum splitting strength and compressive strength of cement-treated aggregate is suggested based on laboratory testing results of material and mechanical analyses with BISAR software during construction.The material of cement-treated aggregate based on new strength standard has the enough strength and little shrinkage that is helpful to decrease shrinkage crack of cement-treated aggregate and reflective crack of asphalt layer.
