| 摘 要： | 在Stovall理论的基础上,通过Stovall模型推导出沥青混合料中连续粒径粉体的堆积密度,然后利用堆积密度与沥青混合料抗车辙能力之间的定量关系计算出一种沥青混合料AC-13的抗车辙型配合比,同时用常规方法设计出另外两种沥青混合料AC-13的配合比。通过马歇尔常规试验和车辙试验对三种配合比沥青混合料的高温稳定性、水稳定性和渗水系数进行对比的结果表明,按照新方法计算抗车辙配合比的沥青混合料的高温稳定性和水稳定性均为最佳。

| Abstract: | Based on the theory Stovall,it derives the bulk density of the continuous particle size powder in the asphalt mixture.Studying on the quantitative relationship between the bulk density and the rutting resistance ability of the asphalt mixture,we can calculate a new anti-rutting-type mix composition of asphalt AC-13.Get the other two AC-13 asphalt mix composition in the original ways.Through the Marshall routine-test and the rutting test,it compares the high temperature stability,water stability and seepage ... |
