| Pervious
concrete pavement is a unique cement-based product whose
porous structure permits a free passage of water through
the pavement into the soil without compromising the pavement’s
durability or integrity. This concrete also goes by other
names including “permeable” and “enhanced
porosity.” |

As
a generic material, all have been recognized by the U.S. Environmental

Pervious
Concrete is a zero-slump, no-fines, open-graded material
consisting of Portland cement, coarse aggregate, admixtures,
and water. The combination of these materials will produce
a product that will allow water to pass through it. The
void structure is normally between 18-to 25%. Compressive
strength designs are in the range of 3000 to 4000 psi.

Drainage rate
will vary with aggregate size and density of the mix, but will
commonly fall into the range of 12 to 18 gallons per minute,
per SF.
