How to prevent roads from freezing after snowing? How do people prevent skidding when the road freezes on snowy days?

1, deicing agent is used to deice. If the ground freezes, you can melt the ice by spraying deicing agent on the ground. After the ice and snow melt, the snow and accumulated ice can be cleared quickly. This is a common method of removing ice and snow. As the name implies, snow melting agent refers to a chemical substance that can reduce the melting temperature of snow and ice. Common snowmelt agents are easy to obtain and low in price, and their components are mainly potassium acetate and chloride, and they are classified. Snow melting agent can melt the snow on the road surface by reducing the melting temperature of snow and ice, which is convenient for road dredging and has obvious sowing effect, but it is harmful. It is found that the residue of snow melting agent will corrode the road surface and automobile rubber tires. At present, shoveling sand and snow are still the main methods in normal winter in the north, supplemented by snow melting agent to remove snow and ice on the road surface, so as to ensure smooth traffic.

2. Sprinkle salt for deicing, or sprinkle salt on the ground to melt the ice on the ground. Just sprinkle a thin layer of salt, then let it stand for about fifteen minutes to melt the ice quickly, and then it can be easily removed.

3, hot water deicing, you can also pour hot water on the ice to deice. This method is easy to melt ice, but it should be noted that it must be quickly deiced when the ice melts to prevent the melted ice water from condensing again.
