PROBLEM TO BE SOLVED: To provide pavement which can positively suppress temperature rise thereof even under the condition of small amount of precipitation. SOLUTION: The pavement is comprised of a water retaining layer (2), a vertical hole (4), and a groundwater supply layer (6). The water retaining layer (2) includes a pavement surface and is formed of a material having water retentivity (porous concrete, water-retaining mortar, water-retaining grout, an open- grain size asphalt mixture, etc., for instance). The vertical hole (4) communicates with the water retaining layer (2) and a groundwater basin (W), and has its interior filled with a material producing capillarity (a fibrous material like polymer fibers, various water retaining materials, etc., for instance). The groundwater supply layer (6) is arranged under the water retaining layer (2) (in a range between a substrate (8) formed of dense-grain size asphalt concrete or the like and the water retaining layer 2, for instance), in a manner communicating with the vertical hole (4), and has its interior filled with a material producing the capillarity (a fibrous material like polymer fibers, various water retaining materials, etc., for instance).
