Slipping and sliding are virtually eliminated with pervious
concrete. Pervious concrete is inherently resistant to freeze-thaw
damage and is gaining recognition in northern climates for its
snow-handling characteristics. As snow melts on pervious concrete,
it immediately passes through the pavement reducing the safety
concerns associated with adverse weather.
Pervious concrete can be designed and installed for use in
commercial parking areas to manage stormwater in a cost effective
way. Installing a pavement that manages both truck loading and
stormwater runoff can reduce both the initial cost of development as
well as the long term maintenance cost of the facility. The bus
parking lot for the City of Athens, GA is an example of development
that is both environmentally and economically sustainable.
Fishing at the Amicalola River in Dahlonega, GA is accessible and
fun for everyone since pervious concrete has been installed
providing a stable, wheelchair-friendly environment adjacent to the
river, while protecting water quality. The pervious concrete drive
along with the handicapped parking area and fishing platform
approach is just the ticket for helping eliminate excessive run-off
into a highly sensitive cool-water trout stream
Urban areas are often times up to 8 degrees F warmer than the
surrounding rural areas, creating "urban heat islands" due to heat
absorbing pavements and roofs. Using thermal imagery, this NASA
photo shows dark pavements (red in photo) in excess of 120 degrees
F. Cooler parking surfaces resulting cooler ambient air temperatures
and reduce the need for air conditioning, saving energy and reducing
power plant emissions. The light color (high albedo) of pervious
concrete reflects thermal heat while the open void structure allows
the earth's cooler temperatures from below to cool the pavement.
Leadership in Energy and Environmental Design (LEED) is a point rating system devised by the U.S. Green Building Council (USGBC). This credit-based system allows projects to earn points for environmentally friendly actions taken during the construction and use of a building. Using pervious concrete can increase the number of points awarded to a building in the LEED system. The stormwater system and light-colored pervious concrete contributed to the East Atlanta Library LEED certification.
