Permeable pavement (PP) is a modified form of asphalt or concrete with a top layer that is pervious to water due to voids intentionally created during mixing. PPs include pervious concrete, porous asphalt, and interlocking concrete pavers. These materials are used as stormwater treatment practices in urban areas. They are used in place of traditionally impervious surfaces to allow infiltration and storage, thus reducing runoff (see figure 1).
