Abstract The model of super-hydrophobic bionic cement concrete pavement was prepared, combining micro-nano pavement building with super-hydrophobic material coating technology. The coating technology of super-hydrophobic materials was studied and the preparation process was analyzed. Anti-icing performance was tested by self-designed ice-road adhesion strength testing device, the contact angle and durability were tested, the surface energy was calculated, then the anti-icing performance of super-hydrophobic bionic cement concrete pavement was evaluated comprehensively. The results indicate that the residual rate of ice on the surface of super-hydrophobic cement concrete specimens is 29.9%, which is about 1/3 of the common specimen, showing good anti-ice perfor-mance. The contact angle of the super-hydrophobic cement concrete specimen is 153.5°, while the contact angle of the common specimen is 0°. The calculation of surface energy reveal that the construction of the super-hydrophobic coating can reduce the surface energy, merely 3.4% of the ordinary cement pavement. It is further verified that the super-hydrophobic cement concrete pavement can significantly reduce the ice-road adhesion strength. The contact angle is still above 90° by simulating the friction between the tire and the road surface, indicating that the super hydrophobic pavement has good durability.

Key words： super-hydrophobic anti-icing cement concrete pavement adhesion strength surface energy effectiveness eva-luation
