| 摘 要： | 针对沥青路面在超载和高温共同作用下的路面车辙进行研究,通过合理路面结构参数的选取,采用有限元分析了路面结构层内部的应力,利用合适的车辙预估模型进行车辙计算,并研究了不同轴载作用下的车辙量的变化。研究成果对于认识高温、超载对路面车辙的影响提供了定量化的判断依据。

| Abstract: | Based on research on asphalt pavement rutting under the combined effect of overload and high temperature and selection of reasonable pavement structural parameters,finite-element analysis is made for internal stress of pavement structure layer;rutting calculation is made by utilizing proper rutting estimate model;and research on rutting change under the effect of different axle load is made.The research result provides certain quantitative judgment basis for the influence of high temperature and overload on pavement rutting. |
