Join principal pavement engineer, David Hein, P.Eng., in an exploration of permeable asphalt, concrete, and interlocking concrete pavement key features and structural design comparisons, as well as design, construction, and maintenance best practices, tools, and methodologies for municipal and parking area hydrological and structural design.
Stormwater management is a key component of urban infrastructure design. If properly designed and constructed, porous pavements can help rainwater infiltrate soil, decrease urban heating, replenish groundwater, and reduce overall storm water runoff. Today, the construction of permeable pavement systems that can accommodate surface water runoff is gaining increased attention through the Leadership in Energy and Environmental Design (LEED) program.
In a 1999 stormwater technology fact sheet on porous pavements, the US Environmental Protection Agency (EPA) indicated that porous pavements traditionally carry a failure rate of over 75%. However, failure was generally attributed to poor design, inadequate construction quality, improper treatment of the subgrade soils, and overloading of under designed pavements. With the issue residing in construction, maintenance, and management (rather than in the permeable pavement solution), increased attention has been (and should be) placed on proper construction, maintenance, and management of permeable solutions to render successful results. As a result, recent studies in the United States, United Kingdom, and Australia have shown the significant benefits of permeable pavement designs.
This session will provide background on the key features of permeable asphalt, concrete, and interlocking concrete block pavements along with guidance, design tools, and methodologies to assist in designing pavements to accommodate hydrological and structural pavement design for municipal and parking area permeable pavements and compare equivalent structural designs.
