To provide a new covering structure which is excellent in rapid-construction properties, interlaminar bonding properties, and surface finishing properties, by combining and using a concrete layer or an asphalt layer, a polymerizable unsaturated resin layer, and a urethane resin layer containing natural oil and/or a derivative thereof and a polyisocyanate compound as essential components.
This covering structure at least comprises: the urethane resin layer (A) which is obtained by using the natural oil and/or the derivative thereof (a-1) and the polyisocyanate compound (a-2) as the essential components; the polymerizable unsaturated resin layer (B); and the concrete layer or the asphalt layer (C). The layers (A), (B) and (C) are arranged in this order from the top face.
