PROBLEM TO BE SOLVED: To prevent clogging of a headrace member, and to arrange a feed pipe without affecting the ground surface even in a large plot, by forming the feed pipe for moistening the road surface in a culvert type, and completely burying the feed pipe in the ground. SOLUTION: The wet pavement system is comprised of a water-permeable pavement material 5 forming the ground surface and has water absorption properties, and a culvert 12 embedded within the pavement material 5, for allowing water to flow therein. The wet pavement system further includes a headrace member 3 and headwaters. The headrace member 3 has one end thereof immersed in the culvert 12 and the other end thereof arranged under the surface of the pavement material 5, whereby part of water in the culvert 12 can be transmitted to the pavement material 5 by capillary action. The headwaters supply water through the headrace pipe into the culvert 12.
