摘要
针对半柔性路面的结构组成方式与构造机理,对沥青混合料基体设置的空隙率与所对应的水泥砂浆进行试验研究与分析,以探究沥青混合料基体在的不同空隙率下得到的半柔性路面材料的路用性能,结果表明:随着空隙率设置的越大,水泥砂浆的灌入量越大,其抗车辙性能随水泥砂浆的增大而增大;劈裂抗拉强度随设置空隙率的增加而减小。
In view of the structure composition and structure mechanism of semi flexible pavement,the experimental research and analysis are carried out on the void ratio of asphalt mixture matrix and corresponding cement mortar,so as to explore the road performance of semi flexible pavement materials obtained under different void ratios of asphalt mixture matrix.The results show that the larger the void ratio is,the more cement mortar is poured,and the anti rutting performance increases with the increase of cement mortar,and the splitting tensile strength decreases with the increase of voidage.
