Abstract Super-hydrophobic coating has super-strong hydrophobic property, which can delay pavement icing and has good anti-icing effect when used on asphalt pavement surface. However, the coating has the disadvantages of easy falling off and poor wear resistance, resulting in insufficient durability of ice and snow melting function. In order to improve the surface stability and durability of super-hydrophobic anti-icing coa-ting, this paper adopts the composite design scheme of "functional layer + adhesive layer", studies the material composition and proportion of functional layer and adhesive layer through experiments, and tests and evaluates the anti-icing effect and surface stability of composite coating. Through research and analysis, the functional layer was suggested to adopt hydrophobic SiO₂ and Fe₃O₄ for nano-composite modification to improve the poor wear resistance and easy reflection of super-hydrophobic coating. Based on the test results of contact angle and rolling angle, it is recommended that the optimal content of anti-wear filler SiO₂ and color blending material Fe₃O₄ are 2% and 2.5% of slurry mass respectively. It is suggested to use epoxy resin mixed system to improve the adhesion between the coating and the road surface. Based on the adhesion test results, the optimal ratio of epoxy resin, curing agent and epoxy toughening agent in the mixed system is determined to be 2∶1∶0.2. At the same time, the microscopic morphology of each layer was analyzed by SEM, and the action mechanism of each layer of materials was expounded. Finally, the road performance test results of the composite super-hydrophobic anti-icing coating show that the composite coating has good stability and durability, can resist dynamic water scouring and freeze-thaw cycles, and has good anti-icing performance.

Key words： super-hydrophobic anti-icing composite coating wear resistance and high viscosity pavement performance
