摘要
车辙是沥青路面的主要病害之一,目前对车辙研究大部分基于恒定温度条件,本研究将以蠕变模型为基础,通过实验得到参数,利用ABAQUS有限元程序增加温度场等环境参数真实模拟的实际路面车辙发展规律,计算道路达到破坏标准的使用寿命。
Excessive rutting would cause asphalt pavement failure. Most laboratory testing only involves in simple constant conditon at a representive average temperature. An useful predictive method for rutting was applied over a wide range temperatures in this paper, ABAQUS finite element software was used to prediet rutting of pavement based on creep model and plenty creep test results. Temperature field was applied to predictive model equation to simulate realistic circumstance. The service life of pavement has been predicted by rutring model.
