Focusing on the purpose of exploring new methods, new materials and new energy, we carried out research on the technology of snow melting and ice melting pavement (pavement, bridge deck and pavement) of environmental protection and new energy (solar energy, wind energy, geothermal energy and electric control), conquered photovoltaic, photothermal solar energy, electric energy, intelligent spraying, high-efficiency electromagnetic energy and other new ice melting technologies one by one, and successively built snow melting and ice melting bridges in Tibet national highway 318, Anhui Fuyang Xincai expressway ramp bridge, Liaoning Benxi ajialing tunnel exit Jinan Municipal Third Ring Road and other areas have paved physical application projects. Up to now, the projects are in good operation, which has obvious practical significance in controlling ice and snow disasters and ensuring smooth traffic.
