Organization: ACI
Publication Date: 1 March 2010
Status: active
Page Count: 44
scope:

Concern has been growing in recent years toward reducing the pollutants in water supplies and the environment. In the

pavement, pervious-a pavement comprising material with sufficient continuous voids to allow water to pass from the surface to the underlying layers.

percolation rate-the rate, usually expressed as inches per hour or inches per day, at which water moves through pervious concrete.

porosity-the volume of open and connected interstitial void space in pervious concrete.

raveling-the wearing away of the concrete surface caused by the dislodging of aggregate particles.

runoff-water from rain or snow that is not absorbed into the ground but instead flows over less pervious surfaces into streams and rivers.

surface course-the top layer of a concrete pavement structure.

void content-the ratio of the volume of voids, including both entrapped and entrained air, to the total volume expressed as a percentage.
