摘　　要：沥青混凝土路面车辙是沥青混凝土路面最主要的病害之一。由于车辙的出现,严重影响了路面的使用性能和服务质量。因此,分析沥青混凝土路面车辙形成机理和影响因素,并在此基础上提出有效的防治措施,是极为迫切的问题。从层间连接、上面层空隙率、上面层级配、各面层密度等方面分析了某高速公路沥青混凝土路面车辙的形成机理和产生车辙的主要因素,并提出了改进建议,供工程实践选用。Rutting damage of asphalt concrete pavement has become one of the most main disea- ses. The performance and service quality of asphalt concrete pavement are descended because of rutting. So formation mechanism and influence factors of rutting are analyzed and the control measures are put forward, they are still a very exigent task. The research on interlayer connection, the voids of surface course ,the aggregate gradations of surface course, the density of each layer is made in order to study the formation mechanism of rutting and analyze the influence factors of causing rut. In the end, some improvement suggestions are presented. The research findings can be consulted in engineering practice and design.
