Use of Crumb Rubber in Flexible Pavement

Today the clearance of different wastes produced from different Industries is a great problem. These materials pose environmental pollution in the nearby area because many of them are non-biodegradable. Crumb rubber is one of them. Soil, stone aggregate, sand, bitumen, cement etc. are used for road construction. Natural materials are limited in nature, its quantity is decreasing and cost is increasing. Afraid about this, engineers are looking for other materials for highway construction, by which the quality of road is increased with low cost. Keeping in mind the necessity for bulk use of these solid wastes in India, it was thought convenient to test these materials and to develop conditions to enhance the use of waste tyres in road making in which higher profitable returns may be possible. The waste tyres can be recycled in the form of aggregate which on mixing with bitumen in suitable size. The article presents a comparison of the mechanical characteristics measurements of the structural layers of road pavements built from the recycled and natural aggregate. Under this research the utilization of waste tyres that can be used as a good purpose for the preparation of the flexible pavement is done.
