摘要：
This paper evaluates the healing performance of recycled asphalt mixture modified with steel wool fibers (SWF) using induction heating method. The optimum SWF content was determined through conductivity and microstructure tests. The healing performance of SWF modified recycled asphalt mixture with different rejuvenators and cooking oil waste was evaluated. The testing results shows that the presence of RAP reduces the induction heating effectiveness due to the long-time oxidization and aging process. For the self-healing purpose, it was suggested that an addition of certain rejuvenator or cooking oil waste with low viscosity can enhances healing performance of the recycled asphalt mixture.
