WATER RETENTIVE PAVEMENT STRUCTURE
PROBLEM TO BE SOLVED: To improve cooling effect of a road surface temperature and to extend duration of cooling effect for a road surface greatly, compared with the prior art.SOLUTION: A water retentive pavement structure comprises: a water passing route which is continuous to allow water to flow between a roadbed 20 comprising a single grain aggregate 21 of high porosity, a sand layer 50 and a permeable pavement 60; and a water passing route which is continuous to allow water to flow between a water retentive cell structure 30, a water absorption sheet 40 and the permeable pavement 60, by bringing a flat part 41 of the water absorption sheet 40 into contact with the top face of the water retentive cell structure 30 with a water-liftable function while top parts of a plurality of raised parts 42 formed to project on the top face of the water absorption sheet 40 are brought into contact with the undersurface of the permeable pavement 60.SELECTED DRAWING: Figure 2
【課題】路面温度の冷却効果が向上するとともに、従来と比べて路面の冷却持続期間を大幅に延長すること。【解決手段】空隙率の大きな単粒度骨材２１からなる路盤２０、砂層５０、および透水舗装６０の間を通水可能に連続した通水ルートと、揚水機能を有する保水セル構造体３０の上面に吸水シート４０の平坦部４１を接面させるとともに、吸水シート４０の上面に突出させて形成した複数の隆起部４２の頂部を透水舗装６０の下面に接面させて、保水セル構造体３０、吸水シート４０、および透水舗装６０の間を通水可能に連続した通水ルートを具備すること。【選択図】図２
