摘要
通过对贫混凝土基层厚度与水泥稳定碎石底基层厚度对路面结构各力学指标的影响进行计算分析,总结出各自的影响规律,提出适合于二级公路的贫混凝土基层厚度以及水泥稳定碎石底基层的厚度范围,可为结构设计提供依据。
Based on the calculation and analysis of the influence of the thickness of the lean concrete base and the cement stabilized macadam subbase on the mechanical indexes of the pavement structure,the influence laws are summarized,and the thickness ranges of the lean concrete base and the cement stabilized macadam subbase that are suitable for the secondary highway are proposed,which can provide basis for the structural design.
