Preparation of Water Absorbing Pavement Material from Fly Ash

Fly ash generated from thermal power plants are considered to be a major environmental pollutant due to the toxic material. As per the recent development, fly ash presently is getting dumped as a waste. Being highly fine in nature, it has got high contribution in air pollution and water pollution. Many attempts have been made to utilize fly ash in various aspects such as mine filling, preparation of bricks, different concretes, textiles and many other applications. In concrete most of the research are concentrating on preparation of high tensile strength concrete which can't absorb water into it. In the present study, an attempt has been made to prepare a pavement composite which can absorb water. It has been found that utilization of such a composite material for the purpose of pavement preparation will help for groundwater recharging.
