Abstract:
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 elastomericmaterials 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%.
