Due to the characteristics of asphalt materials, the asphalt pavement is softened at high temperature in summer, and pavement diseases are easily caused under the action of vehicle loads. The ice and snow cover the road surface in winter, not only influence highway traffic capacity but also can cause the potential safety hazard to driving.
The pavement cooling in China mainly comprises three modes of paving a heat reflection material, adding a phase change material into an asphalt mixture and sprinkling water. However, the problems of high cost, high construction difficulty and the like exist in laying the heat reflection material. The problem of poor stability exists when the phase-change material is added into the asphalt mixture. The sprinkling cooling mainly comprises two modes of sprinkling cooling by vehicles and sprinkling cooling by nearby pumping underground water, but the mileage of the highway is long, the sprinkling cooling by the vehicles is difficult to meet the cooling requirement of the asphalt pavement of the highway, and the exploitation of the underground water easily causes uneven settlement of structures such as roadbed, bridges and culverts along the line, thereby influencing the service life of the structures.
China mainly comprises spreading a snow-melting agent, mechanically clearing and thermally melting snow on roads. However, the snow-melting agent is difficult to melt at low temperature, so that the snow-melting agent has the problems of poor effect and high comprehensive cost, and most of the snow-melting agents are corrosive and easily damage the pavement structure and the ecological environment. The mechanical cleaning method has the problems of poor cleaning effect, large manpower requirement, delayed cleaning, reduced road traffic capacity during cleaning operation and the like. Although the thermal ice and snow melting method has good effect, the method has the problem of large energy consumption. The requirement cannot be met by simply utilizing solar energy and wind energy, meanwhile, the highway is long in mileage, and the cost for erecting power supply lines along the highway is high.
