AGE BITUMEN REJUVENATION INCORPORATING REJUVENATORS
Abstract
To restore the performance of old bitumen which has been stiff and hard to become maltenes, it is necessary to add a rejuvenator to makes the old bitumen will soften and the performance of the bitumen will increase. This paper presents the results of physical property tests of aged bitumen incorporating rejuvenators. The physical property tests conducted were Penetration, Softening Point (SP), and Viscosity (VIS), The rejuvenator in the form of oil-based namely ceca base was added with the variation of 0.3%, 0.5%, 0.7%, and 1.0% from the weight of bitumen. The result shows that the penetration increase and viscosity decrease with the addition of the ceca base. While The SP and BBR tests show the inconsistent pattern
