摘要
车辙是沥青路面的主要病害之一。提出路面下层禁止采用密实的粗骨料沥青混凝土,推荐使用大孔隙率、高碎石含量的沥青混凝土,能保证碎石直接啮合使骨架稳定,从而可避免车辙形成。
Presented here, compacted coarse asphalt concrete is prohibited to be used in the road below, and it is recommended to use large porosity, high content of gravel asphalt concrete . It can make the gravel mesh directly and guarantee the skeleton stable, which can avoid the formation of rutting.
