This study presents the properties, performance and findings on crumb rubber as asphalt modifier and accomplishes the comparison between the performances of Crumb Rubber Modified Asphalt over conventional asphalt, the rheological and mechanical performances of various mixtures evaluated by different experimental techniques. In this study it is observed that with increase in percentage of the fine CR in the mix resulted in increase of viscosity and a decrease in resilience of pavement. CR modification at high additive content exhibited higher elastic response than the styrene butadiene styrene (SBS) modified mixture. It is evident from the various researches and studies that CRM asphalt can increase high temperature stability, strengthen low temperature crack resistance, enhance water stability, durability and fatigue resistance of asphalt pavement. The use of crumb rubber in the asphalt binder has great advantages including increase in life of pavement, retarded reflection cracking and thus reducing maintenance cost of the pavement.
