摘要
车辙是沥青路面的一种常见破坏形式,类型有多种。针对其中最主要的失稳型车辙,分析其形成原因以及影响因素。研究发现,车辙主要是由于剪应力作用下沥青混合料发生剪切流动变形而产生的。
Rutting is a principal kind of failure for asphalt pavement. There are many types of rut ting, in which the major one is caused by asphalt instability. In this paper, the rutting mechanism and the factors influencing the rutting were studied. From the research, it was found that rutting is most ly caused by the shear flow deformation of asphalt mixture due to the shear stress.
