摘要 This paper investigates the effects of types and aging of asphalt binder on healing performance of asphalt mixture modified with steel wool fibers(SWF)using induction heating method.Asphalt binders PG58-22,PG64-22 and PG76-22,widely used in Korea,were applied in this study.The rolling thin film oven(RTFO)and pressure ageing vessel(PAV)tests were conducted to simulate the aging process of asphalt binder.The healing performance of mixtures was evaluated by the crack-heal process,which included semi-circular bending and induction heating tests.The cooking oil waste was used as a rejuvenator in order to refresh the aged binder and its healing performance was also examined.The results indicated that the performance grade(PG)of asphalt binder slightly affected the healing performance of mixtures due to the difference of binder viscosity.In addition,the healing level of asphalt mixture was reduced significantly by aged asphalt binder.Finally,it was found that using cooking oil waste as a rejuvenator for the aged asphalt mixture can improve its healing performance.
