浸透性舗装(Porous Pavement)

ORESU-G-11-002 P pavement (also known as permeable and pervious pavement) is a stormwater management facility that allows water to move through void spaces within the pavement and eventually infiltrate into underlying soils. In many cases, it can be used instead of conventional, impervious pavements for both vehicular and pedestrian traffic, without the need for any additional stormwater management feature such as a detention basin or a rain garden. These systems reduce volumes of runoff that would otherwise be produced by impervious surfaces such as parking lots, roads, and sidewalks. Three primary variations of porous pavement surfaces exist, providing several aesthetic options.
