Winter ice and snow weather, road icing has become a problem for people, pedestrians have a difficult road, driving and slipping problems. The elderly children in the snow and ice weather did not dare to go out. Nowadays, a new type of pavement anti-icing coating liquid is applied on the bridge deck near the toll station of the 328 National Road. It is reported that this paint will test 7500 square meters on the road in Yangzhou, and it is expected to be promoted in the province after its success. It is reported that this new type of road deicing coating material, in the winter snow and ice weather, the road has it will not freeze. Dr. Hu Guangwei, Director of the Pavement Technology Research Institute of Jiangsu Provincial Transportation Planning and Design Institute, said that this coating has been successfully tested in Ninghuai Expressway and Zhejiang Province. It is the first time this material has been tested in the national trunk line in Yangzhou. After success, it will be promoted throughout the province. However, according to reports, even if it is promoted, not all roads will be promoted, but it will be promoted on pavements, bends, slopes and urban entrances and exits that are easy to freeze. New paint drops freezing point below -30°C In the Yangzhou experimental pavement deicing coating material, the principle is to reduce the freezing point of snow. Hu Guangwei introduced that under normal circumstances, the snow water freezes at 0 °C, and this new material is applied to lower the snow water freezing point below -30 °C, and it is difficult for Yangzhou to have a temperature of -30 °C. Moreover, this layer of antifreeze material is applied. Even if the road surface is frozen, it is only a thin layer. It does not stick to the asphalt pavement. When the wheel is rolled, the thin ice is broken because the new coating forms a gap between the ice and the asphalt pavement. The layer of thin layer is easy to fall off. Last winter, there was no snow and ice on the section of the Ninghuai Expressway that was sprayed with new coatings, and there were thick ice and snow on the sections that were not sprayed. Hu Guangwei introduced that through many laboratory experiments and experiments in Ninghuai Expressway, this coating material can continue to melt snow deicing in a winter, and it can work in 8 snows, but it needs to be re-sprayed after one winter. According to the current climatic conditions in Jiangsu, the next 8 snows in winter are very rare. In addition, the coating material has no negative impact on the road surface, steel structure, pavement facilities and the like.
