摘要
考虑沥青混合料在不同温度条件下的车辙情况,充分模拟路面的实际受力情况,进行四种不同级配沥青混合料(分别为GAC-13、GAC-20、GAC-25和ATB-25)三轴重复加载永久变形试验,分析和研究沥青混合料在标准轴载0.7MPa与不同温度水平作用下的流动变形特性,并将三轴试验与车辙试验的结果进行比较。目的在于提出能够有效评价沥青混合料高温性能的指标。
Considering rutting of asphalt mixture under different temperature conditions and fully simulating the actual force bearing status of pavement, triaxial repeated load permanent deformation tests on four kinds of asphalt mixtures with different gradings （ respectively GAC - 13, GAC - 20, GAC - 25 and ATB - 25 ） are performed, and analysis and study on flowing deformation characteristics of asphalt mixture under the effect of standard axle load 0.7MPa and different temperature levels are performed. The results of triaxial test and wheel rutting test shall be compared, so as to put forward the high temperature performance parameter of effectively evaluating the asphalt mixture.
