主 题:Asphalt mixture Induction heating Steel wool fibers Healing Aging Cooking oil waste
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 *** binders PG58-22,PG64-22 and PG76-22,widely used in Korea,were applied in this *** rolling thin film oven(RTFO)and pressure ageing vessel(PAV)tests were conducted to simulate the aging process of asphalt *** healing performance of mixtures was evaluated by the crack-heal process,which included semi-circular bending and induction heating *** cooking oil waste was used as a rejuvenator in order to refresh the aged binder and its healing performance was also *** results indicated that the performance grade(PG)of asphalt binder slightly affected the healing performance of mixtures due to the difference of binder *** addition,the healing level of asphalt mixture was reduced significantly by aged asphalt ***,it was found that using cooking oil waste as a rejuvenator for the aged asphalt mixture can improve its healing performance.
