摘　　要： 车辙是沥青路面在交通荷载反复作用下产生的竖向永久变形的积累,是路面的主 要损坏形式之一。在分析了车辙形成机理和影响因素的基础上,对现有永久变形的预测方法进 行了比较。为今后提出更准确的预测模型以及沥青路面的设计提供了参考。 Rutting is the accumulation of permanent deformation when asphalt concrete pavements are under the repeated application of traffic loads, and is one of the major damage of pavement. Information on previous studies and affecting factors of the permanent deformation mechanism were collected. Various permanent deformation models derived from different assumptions were discussed and compared. It may provide references for giving more correctly models and for designs of domestic asphalt pavement.
