摘　　要：在对当前通用车辙评估试验方法的基础上,提出一种基于全厚式车辙试验的沥青路面车辙预估方法。利用正交全厚式车辙试验,分析了温度、荷载对车辙的影响效应;建立了全厚式车辙试验和沥青路面车辙发展仿真模型,比较分析了全厚式车辙试验结果和沥青路面车辙之间的相关性,表明全厚式车辙试验与沥青路面车辙发展结果线性相关;在此基础上,推导了沥青路面车辙预估模型。提出的沥青路面抗车辙能力评估方法成本低、应用简单。In the analysis of current rut testing methods,a full-thickness rutting test is brought up to predicate rutting development of asphalt pavement.The impacts of temperature and load are analyzed by orthogonal full-thickness rutting tests;and the relation between the results of full-thickness rutting test and asphalt pavement rutting is discussed by developing the numerical models of full-thickness rutting test and asphalt pavement.It revealed that the full-thickness rutting test is linearly correlated with asphalt pavement＇s rutting developing;and then,the rutting predication model is deduced.The proposal rutting prediction model for asphalt pavement is low-cost,applicable.
