The invention discloses a porous concrete base composite asphalt pavement structure, and relates to the technical field of roads. The system comprises a roadbed, and a cushion layer, a rigid waterproof layer, a porous concrete base layer and a drainage asphalt pavement layer are sequentially paved on the roadbed from bottom to top; a plurality of water guide pipes are arranged in the porous concrete base layer at equal intervals in the longitudinal direction; the two ends of each water guide pipe extend out of the two sides of the porous concrete base layer, and the horizontal position of themiddle of each water guide pipe is higher than the horizontal positions of the two ends. A plurality of water seepage holes are formed in the upper surface of each water guide pipe, and a filtering grid is arranged at the opening of each water seepage hole. The multiple water guide pipes are arranged in the porous concrete base layer at equal intervals in the longitudinal direction, water in the road surface can be effectively and smoothly drained, the influence of rainwater on the quality of the road surface structure is reduced, and meanwhile the strength of the porous concrete base layer can be enhanced through the water guide pipes; and cracking, wheel shearing and rutting of a pavement structure can be effectively avoided.
本发明公开了一种多孔混凝土基层复合沥青路面结构，涉及道路技术领域。包括：路基；以及在所述路基上依次从下至上铺筑有垫层、刚性防水层、多孔混凝土基层、排水沥青路面层；所述多孔混凝土基层内沿纵向等间隔设有多个导水管；每个所述导水管的两端均延伸至所述多孔混凝土基层两侧外，且中部的水平位置高于两端的水平位置；每个所述导水管上表面均开设有多个渗水孔，每个所述渗水孔的孔口均设有过滤格栅。本发明通过在多孔混凝土基层内沿纵向等间隔设有多个导水管，能够有效将路面内部的水顺畅排出，减轻雨水对路面结构的质量影响，同时，导水管也能够增强多孔混凝土基层的强度；能够有效避免路面结构的开裂、轮剪、车辙。
