祁临高速公路路面大修时机理论探究

The Study on the Theory of Qilin Highway Pavement Overhaul Time

沥青路面面层直接承受行车荷载和环境的作用,对其最基本的要求是耐久、平整和抗滑。随着通车早期未治超重载车辆的逐渐增多,再加上高速、大流量和渠化交通的联合疲劳作用下沥青路面出现早期损坏。主要针对荷载疲劳作用对沥青路面的影响进行探究,确定基于荷载疲劳作用的路面大修时机及方案。

This paper mainly explored the influence of the load fatigue effect on the asphalt pavement, and determined the pavement overhaul time and scheme based on the load fatigue effect.
