As China is in the subao-European plate, and the breadth of the population is wide, the climate is complex. Except for a small part of regions, most regions have the temperature condition of zero in winter, which has great influence on the road traffic safety of China. If ice layers and accumulated snow on the road surface are not processed in time, the driving safety of citizens is seriously threatened. Meanwhile, the phenomenon of accumulated snow and icing on the road surface can also damage the road surface structure, cause traffic jam and seriously influence national economy, so that the research on the method for preventing/removing the ice on the asphalt road surface has practical significance and economic benefit.

However, the above methods for preventing and removing ice all have the problems of environmental pollution and high cost. With the development of the times and the progress of the society, the sustainable development consciousness of saving resources and protecting the environment is strengthened in the heart of people. In order to meet the development concept of environmental protection, a method for removing ice and snow on the road surface, which has the advantages of good ice-preventing and deicing performance, no damage to the road surface structure, environmental protection and durable snow and ice melting and deicing functions, needs to be researched urgently. Therefore, the research on the ice and snow removing technology with simple process, high cost performance and low energy consumption has important significance for ice prevention and ice removal of the asphalt pavement of the highway.
The super-hydrophobic coating can promote water drops to roll off, delay the icing time of the water drops and reduce the adhesive force between an ice layer and the surface of the coating. But when the temperature is low in winter and rain and snow are large. The rain and snow on the road surface can not be discharged in time, and the road icing phenomenon can still occur. A method for actively removing the ice layer on the road surface is needed. Microwave heating is achieved by the absorption of microwaves by a polar dielectric material, thereby converting the electromagnetic energy of the microwaves into thermal energy of the dielectric. The microwave heating has the advantages of high thermal response speed, less heat conduction process, selective heating and the like.
