柔性基层沥青路面与组合式沥青路面层底拉应力分析

The bottom layer tensile stress analysis of flexible base asphalt pavement and combined asphalt pavement

对两种典型路面结构层层底拉应力进行对比,分析了基层厚度变化对各层层底拉应力的影响,得出两种路面结构层层底拉应力变化规律,根据其变化规律来选择路面结构材料。

In this paper,two kinds of typical pavement structure layers tensile stress of bottom layer were,the analysis of the impact of the thickness variation on tensile stress of bottom layer. We obtain two kinds of change regulation of pavement structure layers tensile stress of bottom layer, and choose the materials of pavement structure according to the change regulation.
