Abstract:
The mechanism of active deicing and snow melting pavement coating with environmental friendly and long-term action was analyzed. The comparative experiment methods of various deicing and snow melting materials were used, and the experiments of snow melting, freezing rain, and secondary icing under artificial environment were conducted. The environmental performance was analyzed through the experiments of carbon steel bar corrosion and watering clover, and the deicing and snow melting performance of road was evaluated in an experimental section. Analysis result shows that when the amount of active deicing and snow melting pavement coating is more than 0.6 kg·m-2, the effect of snow melting is perfect, andone-time construction of the coating can be used repeatedly. Freezing rain and secondary icing can be well inhibited by the coating. The active deicing and snow melting pavement coatinghas little harm to structures and vegetations, and has good environmental performance. One-time construction of the coating can deice and melt snow several times, and the ability of repeated snow melting can meet the long-term requirements for a snowing season. 1 tab, 9 figs, 14 refs.
