Pervious Concrete Void Structure
The permeability of pervious concrete benefits more than the environment-- it also provides increased safety for drivers. When used instead of impervious asphalt as a parking area pavement, pervious concrete substantially improves driving safety during wet weather conditions. Rain seeps down through the concrete rather than remaining on the surface, which eliminates the spraying and pooling of water. This subsequently reduces nighttime glare for the driver and lessens the risk of hydroplaning. Anecdotal evidence also suggests that snow-covered pervious concrete clears more quickly than other pavements, as its voids allow for more rapid thawing.
The picture above demonstrates the significant difference between pervious concrete and asphalt pavements after a rainfall. While the asphalt is visibly slick with rainwater, the pervious surface in the foreground remains unaltered by the weather.
