| As a new type of intelligent bionic materials, the superhydrophobic materials have been widely used in the field of power, aerospace and other fields, due to its excellent hydrophobic and hydrophobic properties. However, in the field of transportation, it is still in the initial stage of exploration. In this paper, the problems of anti-icing technology in highway pavement application at home and abroad are introduced, and the advantages of superhydrophobic anti-icing technology in pavement are analyzed. The basic theory of the wetting property is summarized. The feasibility of using superhydrophobic materials in pavement is demonstrated according to droplet water promotion, crystallization process, ice adhesion reduction. The main factors that influence the ice-road adhesion are analyzed according to the change of chemical composition and roughness of materials. On this basis, the preparation of superhydrophobic materials and the treatment technology of pavement are introduced. This paper summarizes several methods to detect the adhesion between ice and pavement materials at home and abroad, mainly including impact test, horizontal shear test, weight shear test. According to previous studies, the pendulum test and split test are designed. Further validation of the superhydrophobic and anti-icing technology can effectively reduce the adhesion of ice-road. The existing problems of superhydrophobic and anti-icing technology in highway pavement are summarized, and the future research direction is proposed. |
