This study systematically investigated the potential of waste carbon fibers (WCFs) as a sustainable solution in enhancing the multiple induction heating healing of asphalt mixture, thereby tackling two major concerns: the environmental impact of WCFs and the durability of asphalt pavement. Firstly, four groups of asphalt binder samples with different WCFs contents were prepared. The viscosity and workability of WCFs modified asphalt binder were analyzed. Next, asphalt mixture containing 2% steel fibers was prepared at the optimal WCFs content, while control groups without WCFs were prepared with 2% and 4% steel fibers content. A comprehensive study was conducted on the induction heating rate, effective heating depth and surface temperature cooling rules of the asphalt mixture. Finally, by conducting multiple “fracture-healing” tests, the influence of WCFs on the healing efficiency of asphalt mixture was analyzed. The results revealed that WCFs increased the viscosity of the virgin asphalt, but excessive WCFs content hindered the workability. The optimal WCFs content was determined to be 1% (by weight of asphalt binder). WCFs enhanced the thermal conductivity of the asphalt mixture, accelerating heating and improving vertical heat transfer while reducing surface temperature decline. During multiple “fracture -healing” processes, the inclusion of WCFs enhanced the mechanical strength of the asphalt mixture, improved its healing efficiency, and increased the number of healings. Even after five cycles, the specimen with the most damage still showed a fracture energy recovery rate (FERR) of over 30%. In conclusion, WCFs significantly enhanced the multiple induction heating healing efficiency of the asphalt mixture.
