摘　　要：文中主要就混合料类型、路面结构类型、温度及荷载对路面车辙行为的影响进行了研究。结果表明,粗粒式沥青混合料相较于细粒式抗车辙性能更好,下面层采用抗车辙性能更好的沥青混合料对路面结构整体的抗车辙性能提升更大。随着温度升高,沥青混合料车辙永久变形逐渐增大,温度达到70℃时,车辙变形出现明显突变;随着荷载的增大,沥青混合料车辙永久变形逐渐增大。This paper mainly studies the influence of mixture type,pavement structure type,temperature and load on pavement rutting behavior.the results show that:coarse-grained asphalt mixtures compared to fine-grained rutting resistance is better,the folol wing layer with better rutting resistance of asphalt mixtures on the pavement tsructure of the overall rutting resistance to a greater increaes in performance.As the temperature rises asphalt mixture rutting permanent deformation gradually increases,reaching 70℃,rutting deformation appears sudden change;with the increase of load,asphalt mixture rutting permanent deformation gradually increases.
