摘要

PROBLEM TO BE SOLVED: To provide an inexpensive pavement provided with water permeability, water draining capability and water retentivity and its construction method providing compatibility between the water retentivity and the water permeability and water draining capability, and capable of maintaining a cooling function of a road surface for a long time. SOLUTION: The pavement arranged with a layer of an asphalt mixture in a surface layer is provided with a pavement body with a water retention material partially filled in gaps of the asphalt mixture and left with gaps communicating from a top face to a lower face and/or a side face, and a water storage layer laminated in a lower side of the pavement body and surrounded by a waterproof material in a bottom face and side faces.
