RECHARGE OF GROUND WATER THROUGH PERMEABLE PAVEMENT

Abstract

Permeable pavement typically consist of pervious concrete, porous asphalt, permeable interlocking concrete paving units or grid type systems over an open – graded base sub-base layers. Permeable pavements infiltrates storm water reduces peak flow, filter and clean contaminants and promote ground water recharge. Pervious concrete is a porous type of concrete which is widely used nowadays for construction work and for permeable pavement. Since authors noticed that less quantum of research is carried out on this topic hence out of motivation this work under consideration is carried out. In many developed countries, the use of pervious concrete for the construction of pavement, car parks and driveways is becoming popular. In order to develop material specification for pervious concrete, it is necessary to conduct testing to evaluate its performance. Pervious concrete is a zero-slump, open graded material consisting of hydraulic cement, coarse aggregate and water. Because pervious concrete contain little or no fine aggregates such as sand, it is some time referred to as “no-fine” concrete. To achieve the porous concrete ordinary Portland cement is used.
