▎ 摘　　要

Snow and sudden heavy fog on the road are significant factors that contribute to traffic congestion and frequent accidents. In light of a number of environmental, economic, and road corrosion problems caused by road snow melting and fog elimination, this work studies a graphene heating film coupled concrete road snow melting and defogging system, which is critical to the transportation safety and economic and social benefits. The graphene heating film is embedded in the road and electrified as a heat source to analyze its function and effect in the process of melting snow and defogging. Furthermore, the heating performance of the various heating elements is compared and analyzed, and the working temperature, spacing, and buried depth of the graphene heating film is investigated. The rationality and efficiency of the graphene heating film coupling concrete road snow melting and defogging system are verified through experimental and simulation analyses.
