Water Absorbing Pavements by Using Pervious Concrete

Abstract: Pervious concrete is a special type of concrete with high porosity used for concrete flatwork applications that allows water for precipitation and other sources to pass directly through, thereby reducing the runoff from the site and allowing groundwater recharge. It is also called as porous concrete, permeable concrete and no fines concrete. Pervious concrete is made using coarse aggregates with little or no fine aggregates. Pervious concrete can be introduced in low loading intensity parking pavements, walk ways, sub base for concrete pavements, Footpaths and highways. Different properties of pervious concrete e.g. workability, compressive strength, flexural strength test at 7, 14 and 28 days have been studied experimentally. However porosity was the most consider shrewd potency of porous concrete in calculating efficiency of porous concrete which was affected by addition of certain percentage of fiber.
