Abstract

Aging process especially in asphalt binder material can occur throughout the life cycle of asphalt pavement starting from mixing, placement and during the service life. During this process, the more stiffer and brittle of asphalt binder is produced due to age hardening and gives an indication of initial factor of deterioration in asphalt pavement. A number of noteworthy researchers have focused on oil based modification to produce modified asphalt binder by using Waste Cooking Oil (WCO), due to the presence of natural antioxidant properties possessed in WCO. Antioxidant has played the role as an oxidative inhibition and has the potential to minimize the aging rate to occur. The aging process is conducted by separating between short term and long term aging where short term oxidative aging of binders was simulated using rolling thin film oven (RTFO) while long term aging was performed using pressure aging vessel (PAV). The laboratory evaluation was carried out to investigate the relationship between the qualities of WCO that affect the availability of antioxidant amount towards the susceptibility of aging rate by conducting Dynamic Shear Rheometer (DSR). The result from rheological studies demonstrated that the lowest Aging Index (AI) is presented as 2.14, 2.18 and 1.79 for replacement by using WCO in December sample at concentration of 3%, 4% and 5% for short term aging while AI at 3% = 5.17 and 5% = 7.22 for long term aging. Therefore, the high quality of oil represented by WCO in December sample has indicated the high availability of antioxidant content that can minimize the aging susceptibility in the asphalt binder modified by WCO.
