Recently the Interlocking Concrete Pavement Institute (ICPI) released the new Permeable Pavement Comparison Guide. This guide compares the similarities and differences among alternative pavements used for stormwater and sustainable best management practices such as permeable interlocking concrete pavement, pervious concrete and porous asphalt. The guide provides a side-by-side comparison of the available colors, construction efficiencies, costs, winter durability, surface cleaning, repairs, water quantity reduction/water and air quality improvement, urban heat island reduction and recycled content.
It also offers stormwater agencies, design professionals, contractors and homeowners an overview of each system and presents the advantages of permeable interlocking concrete pavement over the alternatives.
As municipalities review their stormwater management programs, many are looking to permeable pavements as environmental and sustainable ways to reduce stormwater runoff. Permeable pavement systems are also recognized as a best management practice by the U.S. Environmental Protection Agency and as a green system by LEED® and GreenGlobes. Permeable interlocking concrete pavement relies on the ability of open-graded aggregate on the surface and base to receive, store and infiltrate runoff back into the soil beneath. Over the past 15 years, permeable interlocking concrete pavement has been researched extensively in North America and overseas.
