Tyre Rubber Modified Bitumen for Ashpalt Mixture

Every nation depends upon exports and imports of goods and services. These goods and services are majorly done by the road ways. The idea of utilizing of Crumb rubber and glass fiber to enhance the properties and pavement performance of the selected asphalt mixtures. Crumb rubber and glass fiber with an additive dosage rate of 0.1 of binder content and 0.5 of aggregate content and increasing the stability and workability of bituminous mix. In order to improve the stability i.e. bonding between aggregates and pavement and pavement performance of asphalt mixtures, two varieties of admixtures Crumb rubber and glass fiber were selected and then combined. A series of tests about pavement performance of base asphalt mixtures and asphalt mixtures with admixture of Crumb rubber or glass fiber were conducted. 0, 0.1 , 0.2 , 0.3 , 0.4 and 0.5 Crumb rubber were added into base asphalt mixtures according to quality to evaluate the pavement performance and 0.5 ,1.0 ,1.5 ,2.0 . and were added into base asphalt mixtures. The performance of asphalt mixtures modified with the optimum content of Crumb rubber and glass fiber were tested to evaluate the improvement of stability at high temperature and enhance the materials strength and fatigue characteristics of above mixtures. These results show that the stability and strength and pavement performance of asphalt mixtures improve obviously. The problem of improving the asphalt mixtures performance with a single admixture is solved, in addition to also improving other pavement performance. D. Vamsikrishna | K. V.
