| 摘 要： | 分析了路面中面层发生早期破坏的方式和机理；从级配的角度出发，筛选了近年来我国沥青路面中面层使用过的4种典型级配，对这4种矿料级配的沥青混合料进行高温性、抗水损坏性以及低温抗裂性试验。根据试验结果进行对比分析，为铺筑沥青路面中面层时合理选择矿料级配提供理论参考。

| Abstract: | First analysis the intermediate surface layer of asphalt pavement early damage occurred manner of destruction and the mechanism. Then,from the perspective of grading, screening in China in recent years in the surface layer of asphalt pavement used by the typical grade, use four types of mineral aggregate grade of asphalt mixture to high temperature performance,water-damaged properties as well as low-temperature cracking test. Based on the test results were analyzed, thus to provide some reference for reasonable choice mineral aggregate grade when paving asphalt pavement surface. |
