沥青混凝土路面表面层混合料的渗水是导致路面结构损伤的重要因素之一。为改善表面层沥青混合料的渗水状况,通过合理的混合料组成设计,对表面层常用AC-13、AC-16沥青混合料进行渗水特性的试验分析。结果表明:两种类型沥青混合料具有不同的渗水特性,级配变异和结构层厚度对渗水特性有明显的影响。研究成果可以用于指导沥青混凝土路面表面层混合料设计。
Asphalt concrete pavement surface layer of mixture of water seepage is one of the important factors that lead to pavement structure damage. In order to improve the seepage status of asphalt mixture on surface layer, the permeability of AC-13 and AC-16 asphalt mixture on the surface layer was tested and analyzed through reasonable composition design. The results show that the two types of asphalt mixture have different water seepage characteristics, gradation variation and structural layer thickness have obvious influence on water seepage characteristics. The research results can be used to guide the design of asphalt mixture on the surface of asphalt pavement.
