New coatings solve the problem of road ice

China Paint Online News: Winter snow and ice weather, road ice has become a problem, pedestrian road difficulties, driving slip problem. Snow and ice old children are afraid to go out. Now a new type of road surface anti-freeze coating liquid in 328 State Road near the old Jiang Wang toll station on the bridge. It is reported that this coating in Yangzhou road will be tested 7500 square meters, after success is expected to be promoted in the province.
it is known that this new road de-icing coating material, in winter snow and ice weather, the road surface with it will not freeze. Dr. Hu Guangwei, director of the Road Technology Research Institute of Jiangsu Provincial Transportation Planning and Design Institute, said that the coating has been tested and successfully on several roads in Ninghuai Expressway and Zhejiang Province, and that yangzhou is the first time this material has been tested on the main road in the province, and will be popularized in the province once successful. However, it is reported that at present, even if the promotion, not all roads will be promoted, but in the bridge, bends, slopes and urban entrances and exits and other easily frozen road promotion.
new coating reduces the freezing point to below -30 degrees C
the road surface de-icing coating material tested in Yangzhou is based on the principle of reducing the freezing point of snow. Hu Guangwei introduced, usually, the snow water to 0 degrees C on the ice, coated with this new material, the snow water freezing point down to -30 degrees C below, and Yangzhou is difficult to appear -30 degrees Celsius temperature. Moreover, coated with this layer of antifreeze material, even if the road surface frozen, but also only a thin layer, non-stick asphalt pavement, wheels rolled, thin ice is broken, because the new coating between the ice and asphalt pavement formed a layer of compartment, thin ice easy to fall off. Last year, on a snowy day, there was no snow and ice on the section of the Ninghuai Expressway that had been sprayed with a new coating, and there was thick snow and ice on the section of the road that was not sprayed.
Hu Guangwei, through a number of laboratory experiments and Ninghuai high-speed experiments, this coating material can continue to melt snow and de-icing in one winter, in 8 snow can work, but after a winter needs to be re-sprayed. According to the current climate conditions in Jiangsu, it is very rare to have eight snows in a winter. In addition, this coating material has no negative impact on pavement, steel structure, pavement facilities, etc.
