摘　　要：沥青稳定碎石透水混合料用于路面结构基层在很大程度上改善和提高了路面结构的排水性能,同时又不降低其结构承载性能。本文基于国外对大孔隙透水材料的试验研究和实际使用状况,针对沥青稳定碎石透水基层混合料的特性,提出了可行的满足路面使用性能的组成设计方法。Asphalt stabilized crushed stone permeable mix, used as the base course in pavement, can significantly improve and enhance the drainage of pavement, while retaining sufficient strength and rigidity of the structure. Based on a review of studies on large pore permeable materials over the world, a method for component design of asphalt stabilized crushed stone permeable mix for pavement base is proposed in this paper, which is proven feasible by test results.
