Porous drainage asphalt pavement structure
The invention discloses a porous drainage asphalt pavement structure which comprises a permeable asphalt mixture surface layer, the water-permeable asphalt mixture lower surface layer is paved below the water-permeable asphalt mixture surface layer; the filtering layer is laid below the water-permeable lower surface layer; the graded broken stone base layer is laid on the soil base layer and located below the filtering layer, a geotechnical cloth layer, the graded broken stone base layer and the filtering layer are laid between the graded broken stone base layer and the filtering layer, and the geotechnical cloth layer is wider than the permeable asphalt mixture surface layer and the permeable asphalt mixture lower surface layer; the side structure layers are arranged on the two sides of the pavement structure, the tops of the side structure layers are flush with the top of the permeable asphalt mixture surface layer, the bottoms of the side structure layers are arranged on the geotechnical cloth layer, and each side structure layer comprises, by weight, 70-90 parts of rock of 10-20 mm, 5-15 parts of machine-made sand of 3-5 mm, 1-10 parts of machine-made sand of 1-3 mm and 4-10 parts of emulsified asphalt.
本发明公开了多孔排水沥青路面结构，包括：透水沥青混合料表面层；透水沥青混合料下面层，其铺设在透水沥青混合料表面层下方；过滤层，其铺设在透水式下面层之下；级配碎石基层，其铺设在土基层的上方，且位于过滤层的下方，其中，级配碎石基层与过滤层之间铺设有土工布层，级配碎石基层和过滤层、土工布层的宽度宽于透水沥青混合料表面层和透水沥青混合料下面层；边部结构层，其设置在路面结构的两侧，边部结构层的顶部与透水沥青混合料表面层的顶部平齐，而底部设置在土工布层之上，边部结构层包括如下重量份数的组分：70～90份的10～20mm的岩石，5～15份的3～5mm的机制砂，1～10份的1～3mm的机制砂和4～10份的乳化沥青。
