摘要
通过对不同最大粒径的透水性沥青混合料空隙率透水性试验结果的分析计算,得到了其透水系数与各空隙率的相关关系。在此基础上可预估透水性沥青混合料的目标空隙率或透水能力。这一结论对透水性沥青路面混合料的配合比设计具有指导意义。
The relation between the percentage of voids and hydraulic permeability of permeable asphalt mixture is obtained through analyzing and calculating the experimental results of the percentage of voids and hydraulic permeability of the permeable asphalt mixtures with various maximum particle sizes. Based on this, the target percentage of voids or hydraulic permeability can be estimated, and this is very helpful for mixture ratio design of the permeable asphalt pavement mixture.
