▎ 摘　　要

NOVELTY - Expressway structure comprises a base layer and a surface layer paved down in sequence from bottom to top. The surface layer includes AC-25 asphalt concrete lower layer, AC-20 modified asphalt concrete middle surface layer and AC-13 modified asphalt concrete upper layer from bottom to top. The middle surface layer of the AC-20 modified asphalt concrete and the upper layer of the AC-13 modified asphalt concrete are also laid side by side with broken water delivery components. A graphene heating film is paved between the lower layer of the AC-25 asphalt concrete and the middle surface layer of the AC-20 modified asphalt concrete. USE - Used as expressway structure. ADVANTAGE - The structure: solves the problem that rainwater accumulates after the road surface is recessed in the traditional technology, which causes spreading and fracture from the recessed place to the surroundings, affecting the driving of the vehicle and limited by the geographical environment, so that the snow melting agent consumption is large and at the same time, it is easy to cause corrosion to the road surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for paving of expressway structure. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic representation of the expressway structure.
