透水沥青路面结构力学性能浅析

基于国内常用的透水路面结构形式,采用APBIH97软件计算了不同类型透水路面结构的半刚性基层层底拉应力、土基顶面压应变。分析结果表明:对于交通荷载轻、交通量小的机动车道,在进行力学分析验证的基础上,可采用半透式沥青路面结构及双层基层全透式沥青路面结构。其成果可为透水路面结构方案的设计提供参考。

Brief Analysis on Mechanical Properties of Permeable Asphalt Pavement Structure

Based on the commonly used permeable pavement structure in China,the APBIH97 software is used to calculate the bottom tensile stress of semi-rigid base layer and the top compressive strain of soil base of the different permeable pavement structures.The analysis result shows that the semipermeable asphalt pavement structure and the double-base full-permeable asphalt pavement structure can be used for the light traffic load and small traffic volume of motored lanes on the basis of mechanical analysis and verification.The result can provide the reference for the design of permeable asphalt structure schemes.
