This document is an extensive review of full-depth permeable pavements including porous asphalt, pervious
concrete, and permeable interlocking concrete pavers (PICP). Also included is a brief section on articulated
concrete blocks/mats. The main topics, which have been divided into chapters, include structural and mix design,
hydrologic design, hydraulic performance (i.e. infiltration capacity), maintenance needs/frequency/actions, the
impact of permeable pavement on water quality, results of a highway shoulder feasibility study, knowledge gaps,
and several cold climate case studies from the United States and Canada.
While progress has recently been made with the relatively new permeable pavement technology, researchers have
also identified many unresolved issues that are not well understood. These include a methodology to measure
subgrade infiltration rates, filling data gaps related to structural integrity, construction, and related issues associated
with permeable pavements, determining what maintenance activities are most effective on various pavement types
and how frequently specific maintenance actions should be performed, a better understanding of the processes
involved in the observed reduction of contaminant concentrations in stormwater flowing through permeable
pavements, and a better understanding of the performance of permeable pavements over a time frame that better
corresponds with a life-span of 20 years.
