In this work, the asphalt mixture was prepared by partially replacing limestone with steel slag, and the self-healing properties under microwave heating (MH) were studied. Firstly, the element compositions of steel slag and its absorbing heating mechanism were analyzed. Then, five groups of semicirc...
