Drainage pavement composite structure suitable for heavy traffic
The invention belongs to the field of road and bridge engineering, and particularly relates to a drainage pavement composite structure suitable for heavy traffic, the drainage pavement composite structure comprises an upper surface layer, a sealing layer, a middle surface layer, an anti-cracking bonding layer, a lower surface layer, a bonding layer and a base layer from top to bottom, the upper surface layer is a high-viscosity composite modified OGFC-13 open-graded asphalt mixture layer, and the thickness of the upper surface layer is 30-50 mm; the middle surface layer is a semi-flexible bearing layer with the nominal maximum particle size of 13.2 mm, and the thickness of the middle surface layer is 30-50 mm; and the lower surface layer is a high-viscosity composite modified discontinuous semi-open graded asphalt mixture layer with the nominal maximum particle size of 19mm or 26.5 mm, and the thickness of the lower surface layer is 50mm-80mm. The drainage pavement composite structure meets the use requirements of heavy traffic on the basis of having the advantages of the drainage pavement.
本发明属于道路桥梁工程领域，具体涉及一种适用于重载交通的排水路面复合结构，包括自上而下的上面层、封层、中面层、防裂粘结层、下面层、粘层及基层，所述上面层为高粘度复合改性OGFC‑13型开级配沥青混合料层，厚度为30mm～50mm；所述中面层为公称最大粒径为13.2mm的半柔性承重层，厚度为30mm～50mm；以及所述的下面层为公称最大粒径为19mm或26.5mm的高粘度复合改性间断半开级配沥青混合料层，厚度为50mm～80mm。该排水路面复合结构其在兼具排水路面优势的基础上满足重载交通的使用要求。
