With the advantages of cost efficiency, noise reduction, and comfort driving experience, asphalt is widely used as a binding material in pavement engineering. However, after years of serving, asphalt concrete gets damaged under cyclic vehicle loading. Meanwhile, due to environmental effects including ageing and moisture damage, asphalt binder becomes brittle with time. As a result, microcracks initiate and grow into larger scales, which accelerates the damaging process and finally leads to distresses like raveling, potholes, cracking, and so on. In 1967, Bazin and Saunier[1] witnessed and reported a temperature related healing phenomenon in asphalt mix after loadings. After that, the healing phenomenon of bituminous material has become a research focus.
