Rheological properties of crumb rubber modified bitumen-A lab study

Praveen Kumar, H C Mehndiratta, Kh. Lakshman Singh

Abstract

In this paper, bitumen is modified with crumb rubber (CR). Changes in rheological properties of 60/70 and 80/100 grades bitumen modified with CR have been studied for rheological properties using Dynamic Shear Rheometer (SR5 Ashphalt Rheometer). CR improves complex modulus and elastic response of bitumen at high temperatures.
