Abstract Ice-adhesion to various materials is a significant concern in all fields. In this paper, the ice-adhesion of asphalt pavement was studied based on the perspective of pavement surface characteristics. Firstly, the ice-adhesion characteristics of asphalt binder, aggregate, asphalt mixture with different surface structures and exposed areas of aggregate (EAA) were analyzed by pull-off test. Thereafter the surface characteristics of the asphalt mixture were studied by laser scanning method. Finally, the influence of freezing temperature on ice-pavement adhesion and the influence mechanism of surface structures on ice-pavement adhesion was explored, respectively. The results showed that the effect of asphalt binder on the ice-adhesion of pavement was not significant, while the effect of aggregate was obvious at −4 and −10 °C. Compared with diabase, gneiss and granite, limestone had better anti-icing performance. The $ SiO_{2} $ and $ Al_{2} $$ O_{3} $ in aggregate mainly promoted the adhesion of ice on aggregate, the CaO, MgO prevented the adhesion of ice on aggregate. With the estimated texture depth and surface area increased, the ice-adhesion strength of pavement decreased and the dropping rate was rapid at the high freezing temperature (−4 ~ −16 °C). With the EAA increased from 0 to 90%, the adhesion strength increased almost 100%. The influence of pavement structure on ice-adhesion is mainly caused by surface structure and failure mode. By studying the ice-pavement adhesion from the perspective of pavement surface characteristics, this paper may provide some fresh insights for ice-adhesion characteristics of asphalt pavement.
