摘要
分析西部地区县乡公路沥青路面典型结构设计参数的敏感性.通过对路基路面设计参数(结构层厚度和材料模量)的变化对路基路面工作状态影响的研究,得到路面结构强度随各结构层设计参数变化规律,确定路面结构的敏感性层位,推荐出设计参数的建议值,为县乡公路土基强度等级划分及路基路面的结构优化设计提供依据.
Sensitivity analysis of the asphalt pavement typical structure design parameters in west county highway was mainly done. Through the research on the influence of the changes of base and pavement design parameters （ layer thickness and material modulus） on the highway base and pavement performance, the change rule between the layer design parameters and pavement strength could be found, and the sensitive layer of pavement might be also decided. Recommends the pavement design parameters for the classification on subgrade strength grades and pavement structure design.
