摘要
大粒径透水性沥青混合料(LSPM)基层是一种路面内部排水结构,能及时排走滞留在路面内部的水分的基础上,能有效地减少反射裂缝的发生。北方寒冷地区路面损坏很多时候是由于冻胀等因素引起的,在研究LSPM材料的抗冻性能的基础上,提出了此材料适合应于寒冷地区,可以降低道路水损坏发生率,提高路面使用寿命。
Large stone porous asphalt mixes（LSPM）base is a kind of pavement internal draining water structure. It can promptly detain pavement interior water, and can effectively reduce the reflection crack. In north cold area pavement is usually distressed because of heave factor. This paper has researched the LSPM frost vesistance performance, and proposed the cold local serviceability.
