中文摘要：

为了研究温度和行车荷载对沥青路面的损坏,应用ABAQUS有限元软件对高速公路沥青路面典型设计方案进行建模,分析温度-应力场耦合作用下沥青路面结构的响应情况。结果表明：应力和位移均随温度产生波动变化;路面结构的波动变化导致路面材料产生疲劳破坏;随着温度的提高,剪应力在面层内部的发散范围增大,面层结构温度升高,出现剪应力破坏的可能性增大。

英文摘要：

In order to study the damages of asphalt pavement under temperature-load coupling effect, dynamic responses of asphalt pavement were calculated under the field of temperature and stress with ABAQUS. The results show that the stress and displacement no longer change uniformly,but show fluctuation under temperature-load coupling effect. The alternating changes of response of the pavem increasing of temperature, the pavement temperature ent structure lea the shear stress , the greater likel d to fatigue failure of asphalt pavement. With the spreads in the surface course. Therefore, the higher ihood of shear failure.
