PROBLEM TO BE SOLVED: To propose asphalt pavement providing sufficient water permeability even if conventional asphalt pavement or concrete pavement is performed. SOLUTION: This invention is a pavement structure being laterally laid and arranged in an impervious layer, a crushed stone layer and the uppermost part from the lowest layer, laying and arranging civil engineering materials composed of a projection part having vertically a through-hole or an easily penetrable projection part and a connecting part for connecting the projection part and exposing the through-hole arranged in the projection part by placing concrete or asphalt from above the civil engineering materials. The pavement structure is characterized by draining rainwater fallen on a pavement surface by laying and arranging a water permeable pipe between an impervious sheet and the crushed stone layer. Water gathered in the crushed stone layer is gathered on the impervious sheet, and is quickly drained by a drain pipe. COPYRIGHT: (C)2007,JPO&INPIT
