Permeable pavements have been gaining popularity throughout North America. Permeable pavements typically consist of pervious concrete, porous asphalt, or permeable interlocking concrete block paving units over an open grade base/subbase layer(s). Permeable pavements are designed to infiltrate stormwater, reduce peak flows, filter and clean contaminants in the water stream, and promote groundwater recharge. They have become an integral part of low-impact design and best management practices for stormwater management. To be effective, permeable pavements must be designed to provide sufficient structural capacity to accommodate the anticipated vehicle loadings and deal with stormwater flowing into and out of the permeable pavement. While there have been many well designed and constructed permeable pavements, this is a relatively new technology and there have been some "issues" with their performance. This paper describes some of the basics of best practices, design, construction, and maintenance considerations for permeable pavement design and construction and focuses on best practices of permeable pavement design and construction in North America.
