Development of Pervious Concrete for Pavement Applications

Abstract

Indian economy is developing at a rapid pace and to maintain equilibrium between nature and growth, it needs to conserve all its natural resources. Complete progress can be achieved by any society if it judiciously uses all resources including water which is the most important one. Also sustainable development is the need of the day. Modern-day infrastructure design principles promote use of impervious materials like concrete and bitumen for construction of parking, curb and gutter systems to rapidly collect and transport rain runoff. Conventional Portland cement concrete and asphalt is used for pavement construction in India, US, UK and other countries around the world. The impervious nature of these construction materials is responsible for the increased water runoff. Under these conditions, storm water reaches the receiving water bodies rapidly, in greater volume and carries more pollutants than natural conditions, all causing an imbalance in the ecosystem. One such material that can be used to produce porous surfaces is pervious concrete, which can play a vital role for solving many environmental issues including depletion of ground water. Pervious concrete pavement on parking lots, sidewalks, and driveways provides solution to this problem. In pervious concrete, carefully controlled amounts of water and cementitious materials are used to create a paste that forms a thick coating around the aggregate particles. The hypothesis for the present investigation on pervious concrete is divided into following compartments. newline1. Development of mixture proportioning of pervious concrete newline2. Construction of pervious concrete pavement and its monitoring newlineThe first phase of this investigation is to develop mixture design of pervious concrete for pervious concrete pavement. Target properties of pervious concrete are assumed for the development of mixture design such as compressive strength, void ratio, permeability and density. The main properties studied include compressive strength, density, and permeability and voi
