Crumb rubber: A sustainable road paving material

Abstract

In the Present Scenario, the use of automobiles has increased significantly and due to that the waste or scrap tyres are also increasing day by day. The waste tyres are classified as solid waste. The proper disposal of these waste tyres has become a serious environmental issue as the tyres are manufactured with synthetic rubber. According to the past records, the scrap tyres were used as a common additive to bituminous binders which not only addresses the pavement performance issues but also tackles the problem of disposal of these tyres. Therefore, In this study an attempt is made to know what percentage incorporation of crumb rubber to bitumen upgrade the strength and durability of the pavement and a comparative study has been done using both wet process and dry process on semi-dense bituminous concrete. Efforts are being made to make it a Sustainable road paving material.
