PROBLEM TO BE SOLVED: To increase the adhesive force and facilitate the works, by forming a synthetic resin waterproof layer on a steel or concrete floor slab and scattering thermoplastic resin particles thereon and then paving it with a heated asphalt mixture. SOLUTION: A liquid synthetic resin having a waterproof property like methacrylic resin, polyurethane resin, epoxy resin, etc., is applied evenly on a floor slab applied with a primer and a substrate treatment to form a waterproof layer. When necessary, before the waterproof layer is cured, non-slip materials composed of silica sand and others are scattered to cope with shifting stresses between layers. A thermoplastic resin particles having 60-130 deg.C of softening point is scattered thereon. And further, the upper face is paved with a heated asphalt mixture. When scattering the thermoplastic resin particles, it is possible to wet the particles with a water solution of a water-soluble polymer or an asphalt emulsion. The adhesive force of respective layers is intensified. In this way, the waterproof property of the asphalt pavement is improved. |
