EXPERIMENTAL STUDY ON PARTIAL REPLACEMENT OF BITUMEN WITH CRUMB RUBBER

Rubber is a non biodegradable material and the disposal of rubber leads to environmental pollution. Therefore, utilizing waste rubber in roads pavements imparts to the properties of roads and to the environment as well. The cost of natural construction materials are increasing day by day, so it becomes necessary to find alternatives to replace the natural resources which may lead to improved quality of roads and reduced constructional costs. Rubber tyres have been proved user friendly to the people in many ways but are not eco-friendly. So it becomes a matter of utmost importance to reuse waste rubber in any means possible. Reusing it as a partial replacement of road materials like bitumen can be an environmental friendly approach.
