| 摘 要： | 沥青路面面层层底拉应变是控制面层材料疲劳损坏的重要指标。应用BISAR3．0（Bitumen Stress Analysisin Road）程序对倒装结构沥青路面面层层底拉应变进行分析，明确了面层层底拉应变与面层厚度、级配碎石过渡层厚度及级配碎石模量的关系。

| Abstract: | The tensile strain which is at the bottom of the surface layers of asphalt pavement is an important index that controls the fatigue damage of surface materials.This paper analyzed the tensile strain at the bottom of surface layers of inverted asphalt pavement structure by using BISAR3.0(Bitumen Stress Analysis in Road) program.Also it clarified the relationship between tensile strain at the end of surface layers and the thickness of surface layer,thickness of graded broken stone layer,as well as elasticity ... |
