Pervious
Concrete Pavement Research

Pervious
paving surfaces provide a desirable combination of stormwater retention and
aquifer recharge properties as a substitute for conventional impervious
pavements. It retains some of the structural properties of conventional
pavements but adds other features such as pollution removal. Portland cement
pervious concrete has generated great interest as a pervious pavement material.
It is a discontinuous mixture of coarse aggregate, Portland cement, admixtures
and water with increased porosity due to limited fines. The increased porosity
due to no fines in the mix and 15-20% air voids allows for the flow of water
through the material.
Pervious
pavements have been used in the past in areas of lower traffic loads such as
parking lots, shoulders for roadways, shoulders for airport taxiways and
runways, street and local roads. The objective of the current research project
is to conduct field and laboratory testing on pervious pavement to address the
issues listed below:
-
Design section
development based on infiltration rates.
-
Credit toward the
reduction of runoff, and
-
Operation and
maintenance programs.
