半刚性与柔性基层沥青路面重载适应性对比分析

The Contract Analysis on Suitability of Semi-rigid Base Pavement and Flexible Base Pavement under over Loading

以路面力学APBI程序为计算工具,对重载车辆荷载作用下的半刚性基层沥青路面和柔性基层沥青路面进行力学响应对比分析,研究路表弯沉、路面结构各层次(包括路表、面层、基层、底基层)的力学特性。结果表明,半刚性路面与柔性路面的重载适应性存在明显差异。通过对半刚性基层与柔性基层结构的合理优化组合,实现两种路面结构的优势互补。

Based on APBI,the mechanical respond to semi-rigid base pavement and flexible base pavement under over loading is analyzed relatively.Meanwhile,the road surface deflection and the mechanical property of layers of pavement are studied.The results show that there are differences between semi-rigid base pavement and flexible base pavement about suitability under over loading.By optimization designing between semi-rigid base and flexible base,the dominant points of the two pavements can be complemented.
