摘　　要：利用加速加载设备MLS66模拟车辆横向分布轮载,同时模拟高温环境因素,修筑专门的足尺典型结构试验段,对微表处填补车辙后的路面车辙变化进行了测试。研究结果表明:对于辽宁省典型的半刚性基层沥青路面结构来说,微表处填补车辙后,路面车辙发展过程与填补前相似,能够起到有效减缓车辙的作用。In this study,the accelerated loading testing equipment MLS66 was used to simulate the lateral distributed heavy vehicle load,and high temperature condition were also achieved.The rutting evolution after the micro-surfacing was measured on the full-scale typical structure test section constructed specially.It is found that the development process of rutting for the classic semi-rigid base asphalt pavement in Liaoning province with the micro-surface is similar to that for the original pavement.It is also shown that filling rutting with micro-surfacing can effectively alleviate rutting.
