Abstract Asphalt concrete specimens with super hydrophobicity and ice resistance were made through introducing the principle of super hydrophobicity. The difference of anti-icing performance of common specimens and super hydrophobic specimens, the difference of anti-icing performance of super hydrophobic asphalt concrete under different environments were tested by simulation test and theoretical analysis. Anti-icing performance of super hydrophobic asphalt concrete was evaluated by contact angle and surface energy. The results showed that super-hydrophobic asphalt concrete could promote the drop of water, the dropping rate could reach 80%. The adhesion between ice and road surface was measured indirectly by self-designed impact test, and the adhesion was 38.5% of the ordinary specimen. The residual rate of ice on the specimen was the least in snowy conditions. The surface energy of super hydrophobic asphalt concrete was 1.97 mJ/m², which was measured by the measurement of contact angle and the calculation of surface energy, it was only 5.1% of ordinary asphalt concrete and showed a good anti-icing performance.

Key words： super-hydrophobicity anti-icing asphalt concrete simulation test surface energy
