Permeable pavement presented in this paper is defined as a type of pavement that has ability to store stormwater until it infiltrates through the subgrade soil and can function as a conventional pavement to carry specific traffic load and speed. Hence, open graded friction course (OGFC) that is an overlay of open graded pavement installed over conventional pavements is not discussed in this paper. Depending on surface pavement, permeable pavements are generally grouped as porous asphalt (PA), pervious concrete (PC), and permeable interlocking concrete pavers (PICP). For permeable pavement to function well, regardless of the type of surface pavement, it is required to satisfy both the structural and hydrologic requirements. If designed and constructed well, then permeable pavement also can act as a best management practice and often viewed as an alternative low impact development option for urban areas.
