A Study on Use of Industrial Wastes in Rural Road Construction
In present scenario safe disposal of Industrial wastes is a great problem. These waste materials create environmental pollution in the vicinity because many of them are non-biodegradable. Studies reveal that in recent years, industrial wastes were successfully used in road construction in many developed countries. The use of these materials in road making is based on technical, economic, and ecological criteria. India has a vast network of industries located in different parts of the country and many more are to come in the near future. Million metric tons industrial wastes are produced in these Industries. The pollution and disposal problems may be minimized by properly utilizing these materials in highway construction. It is important to test these materials and to develop a methodology and specifications to enhance the use of these industrial wastes for their effective utilization in road construction in India. The probable use of these materials should be developed for construction of low-volume roads in different parts of our country. A review of various Industrial wastes to be used in the construction of highway has been discussed in this paper. The common waste materials are fly ash, blast furnace slag, cement kiln dust, phosphogypsum, waste plastic bags, foundry sand and colliery sand.
