▎ 摘 要
NOVELTY - A pavement structure includes an asphalt concrete whose underlying layer is laid on the lime-soil base layer laid on a roadbed. An asphalt concrete mid-layer layer is laid on underlying layer of asphalt concrete. A heat generating layer comprises insulating bonding layer, electric heating film layer and heat conductive bonding layer. The electric heating film layer is located between the heat insulating bonding layer and heat conductive bonding layer. The heat insulating bonding layer is bonded to the surface layer of asphalt concrete, and the heat conductive bonding layer is bonded to the upper layer of asphalt concrete. The electric heating film layer comprises a zinc plate and graphene strips are fixed on the zinc plate. The graphene strips are spaced apart from each other. Several inlaid holes are arranged at positions where the graphene strip is not fixed on the zinc plate. The insulating bonding layer and thermally conductive bonding layer are joined by the inlaid holes. USE - Pavement structure for use in road. ADVANTAGE - The pavement structure has excellent thermal conductivity so that the ice accumulating on the road area is removed in time without affecting the road traffic.
