The self-healing method is one of the most recent technologies used to reduce road distress. One method to accelerate the healing process of asphalt is by using conductive materials in the mix and heating it with electromagnetics. Various materials are used as heat conductors, such as carbon-based fibers and nanofibers, conductive modified bitumen and metal particles. This research uses steel fiber for the Asphalt Concrete Wearing Course (AC-WC). Steel particles were added to the asphalt concrete mixture with varying amount of 0, 0.25, 0.5, 0.75, 1% to the mixture weight. The self-healing test was carried out with a three-point bending test and microwave heating for five cycles to see the healing ratio of each variation. To understand each variation's healing properties, the heating was done for 20, 40 and 60 s. The results showed that the pavement mixture using steel fibers was successful in the self-healing method test. The research results on the mixture with 0% steel particles proved to have self-healing ability but did not give results as good mixtures using 0.25, 0.5, 0.75 and 1% of steel particles.
