摘要
以 JTJ0 5 2 -2 0 0 0《公路工程沥青及沥青混合料试验规程》中沥青混合料车辙试验为基础 ,通过大量试验和理论分析 ,发现规范中用动稳定度指标来评价沥青混合料高温车辙存在着缺陷 ,提出用相对变形率作为评价沥青混合料高温车辙指标 ,更合理完善。
The rutting is a kind of asphalt pavement failure phenomenon, how to evaluate the rutting of asphalt mixture in laboratory is an emphasis to study for highway researcher. On the basis of rutting test of asphalt mixture (JTJ 052-2000), through a series of test and theory analysis, it is found that dynamic stability indictor in standard is not fit to evaluate rutting of asphalt mixture, the relative deformation ratio is a fit indictor to evaluate rutting ability of asphalt mixture.
