基于车辙试验优选沥青高温性能评价指标

Optimized temperature evaluation indexes for asphalt based on rutting test

选择6种沥青分别进行短期老化前后的常规试验、动态剪切流变试验以及重复蠕变恢复试验,得到常规7种高温性能评价指标。将指标排序结果与模拟沥青路面高温性能的沥青混合料车辙试验结果进行相关性分析,选择最优的沥青高温性能评价指标。

Six kinds of asphalt are chosen for the routine tests before and after short-term aging , dynamic shear rheological tests and repeated creep recovery test to get seven indexes for high-temperature asphalt performance evaluation .The indexes are put in order and then compared with the rutting temperature performance test results to optimize the evaluation indexes of asphalt at high temperature .
