超重交通荷载作用下沥青路面的应力分析

Analysis of Pavement Stress under Super-heavy Traffic Loading

以高速公路典型结构为例 ,分析了不同比例、不同程度的超重交通荷载对路面结构的影响。分别从路表弯沉、整体性材料层底拉应力及疲劳寿命、路表车辙等方面说明超重载交通对路面结构破坏性较强 。

This paper analyzes the impact of super-heavy traffic loading on typical expressway bitumen pavement, in different scales and extent, in terms of surface deflection, tensile strain at the bottom of rigid materials and its fatigue life, and pavement rut, which indicate that superheavy traffic will have serious damage impact on the pavement structure and is the major cause of the early damage of the pavement.
