Summary:To provide water permeable and retaining pavement structure and a method therefor that can restrain a temperature rise of a road surface by using ground water.SOLUTION: Water permeable and retaining pavement structure 1 includes water absorbing columns 5 formed by filling foam glass 11 with continuous gap structure of a grain diameter of 1.0 mm to 2.0 mm within holes 10 penetrating a road bed 2 and formed to the depth below a ground water level, a base course 3 that is formed on the road bed 2 and contains the foam glass 11 with continuous gap structure of a grain diameter of 1.0 mm to 2.0 mm, and water permeable pavement 4 formed on the base course 3.SELECTED DRAWING: Figure 1 【課題】地下水を利用して路面の温度上昇を抑制することが可能な透保水性舗装構造およびその工法の提供。【解決手段】透保水性舗装構造１は、路床２を貫通して地下水位以下の深さまで形成された穴１０内に粒径１．０ｍｍ～２．０ｍｍの連続間隙構造の発泡ガラス１１が充填されて形成された吸水柱５と、路床２上に形成された路盤３であり、粒径１．０ｍｍ～２．０ｍｍの連続間隙構造の発泡ガラス１１を含む路盤３と、路盤３上に形成された透水性舗装４とを含む。【選択図】図１
