近年来，为了防止城市地区的河流洪水，有必要开发即使在交通繁忙和/或土壤路基条件下也具有耐久性和足够渗透性的透水路面。实验室试验、全尺寸加速荷载试验和日本各地建设的三年试验路面已明确：1）砂层透水路面具有与普通路面相同的耐久性。 2）当路面需建在土层上时，底基层排水可作为提高其耐久性的有效对策。 3）使用2-3年后其渗透性未恶化。 4）透水路面可以通过减少和延缓径流来有效防止河流洪水。
Development of permeable pavement, which has durability and sufficient permeability even under the condition of heavy traffic and/or soil sub-grade, has been necessary in recent years to prevent river flood in urban region. Laboratory tests, full-scale accelerated loading test and 3 years' test pavements constructed all over the Japan have clarified: 1) Permeable pavement on sand layer has the same durability as the ordinary pavement. 2) When the pavement need to be constructed on a soil layer, drainage from sub base-course could be an effective countermeasure to improve its durability. 3) Its permeability has not been deteriorated after 2-3 years service. 4) Permeable pavement could be effective for preventing river flood by reducing and delaying run-off.
