Pavement structure of recycled aggregate asphalt concrete surface layer
The invention relates to the field of road engineering, in particular to a pavement structure of a recycled aggregate asphalt concrete pavement, and solves the problems that water is easy to retain in a road layer structure, the water continuously destroys the bonding force between asphalt and aggregate in the road layer structure under the action of high-speed traffic load, the asphalt is easy to peel off from the surface of the aggregate, and the service life of the pavement structure is prolonged. The pavement structure comprises an upper surface layer, a middle surface layer, a lower surface layer and a pavement base layer which are sequentially laid from top to bottom, a water retaining layer is embedded in the pavement base layer, and the middle of the water retaining layer is higher than the two sides of the water retaining layer. The road layer structure has the advantages that drainage of the road layer structure is facilitated, and adverse effects of water on the road layer structure are reduced.
本申请涉及道路工程的领域，尤其是一种再生集料沥青混凝土面层的路面结构，解决了水易在道路层结构内滞留，在高速行车荷载作用下，水在道路层结构中持续对沥青和集料间的粘结力造成破坏，易使沥青从集料表面剥离，对道路的荷载强度和使用年限均造成不良影响的问题，其包括由上而下依次铺设的上面层、中面层、下面层以及路面基层，所述路面基层内埋设有挡水层，所述挡水层中部较两侧高。本申请具有方便道路层结构的排水，减少水对道路层结构的不良影响的效果。
