VOIDS ADD VALUE TO PERVIOUS CONCRETE

This article describes new techniques for designing and building pervious or permeable Portland cement concrete pavement, which is gaining popularity in the Sunbelt and Pacific Coast. It can help local communities meet EPA Phase II storm water pollution regulations. It also reduces hydroplaning and tire spray. The final structure has voids in 20-25%. Anything higher tends to compromise compressive strength. In addition to parking lots, pervious concrete can be used in recreation trails, plazas and other paved pedestrian areas. It also cuts down in stored heat in the summer, but its greatest benefit is its effective passive water treatment, which catches non-point pollutants and transfers them to soils where microbes can convert them into harmless materials. While pervious concrete costs more to install, its does eliminate the need for gutters, curbs and storm drains. The article also describes installations at specific sites.
