Abstract
A road structure, an asphalt layer of which is peeled off by electromagnetic induction heating, includes a non-thermoplastic base layer, an asphalt layer located above the base layer, a conductive sheet between the base layer and the asphalt layer, a first bonding layer that bonds the conductive sheet and the base layer; and a second bonding layer that bonds the conductive sheet and the asphalt layer. The conductive sheet is configured to generate heat based on electromagnetic induction. At least the first bonding layer is a thermoplastic bonding layer configured to be softened by the heat.
