目前,国内沥青路面早期破坏现象严重,原因是多方面的,其中有一个主要的原因就是层与层之间的接触界面没有处理好。研究人员针对路面结构的层间状态评价主要采用力学和试验两种手段。力学研究常采用一些力学计算软件如BISAR,ANSYS等计算基层与面层之间由连续变为滑动过程中,不同的层间接触状态对沥青层层底拉应力、 At present, the early destruction of asphalt pavement in China is serious for many reasons. One of the major reasons for this is that the contact interface between layers is not handled well. Researchers for the pavement structure of the evaluation of the status of the main two layers of mechanical and experimental means. Mechanical studies often use some mechanical calculation software such as BISAR, ANSYS calculate the base layer and the surface layer from the continuous into a sliding process, the contact between different layers on the asphalt layer bottom tensile stress,
