Icing on roads in cold regions seriously affects vehicle driving safety. Therefore, this study aims to propose a pavement surface treatment technology with groove-filled elastomer. Through theoretical analysis, the ice-breaking mechanism of groove-filled elastomer asphalt pavement was clarified. Then, through the indoor ice-breaking test, the ice-breaking performance of the asphalt pavement groove-filled with elastomeric materials under three filling forms of above, level and lower than the asphalt pavement surface and different ice thickness were studied. The results show that the filling form where the elastomer material is flush with the asphalt pavement has the best ice-breaking effect, and the groove-filled elastomer asphalt pavement still has an excellent ice-breaking effect when the thickness of the ice layer is less than 2 mm. Finally, through BPN and friction coefficient test, the skid resistance performance of groove-filled elastomer asphalt pavement under dry, wet and icing conditions is verified. Compared with AC-13 asphalt mixture, the skid resistance of groove-filled asphalt pavement is improved by 4.5, 10.8 and 24.6%.
