Can Rock Salt Be Used On Public Streets In The Winter?

Many are wondering about the use of rock salt to melt the ice that’s always a hazard on public streets during the winter season.  In almost all states, winter causes hassles for drivers trying to navigate snowy and icy roadways, causing accidents and injuries throughout the season. Winter weather requires transportation agencies to continually put down a huge amount of rock salt to mitigate the danger of ice and snow and cause it to melt.

In all homes, salt is used to add flavor to dishes that we are cooking, and it’s even used to preserve foods. However, another amazing contribution of salt is to quickly help people stay away from the trouble of ice and snow in the street or other places we need to get rid of snow and ice. To answer such a question in your mind, keep on reading.

Indeed, the answer to your question is absolute, yes. The kind of salt on public roads and streets to melt ice and snow is commonly called rock salt. Its piece of grain is much coarser compared to an ordinary salt we used at home. It still has the same molecule present in it which is sodium chloride, however, compared to table salt, it is not purified, not ground, and has no anti-clumping properties. When you take time to observe the frozen street, the rock salts that are expected to be a large-crystalized rock are directed into the railroad taken by the equipped salt trucks.

  • Rock Salt as The Best Alternative

The use of rock salt is considered to be the best alternative during the freezing point depression because it can lower the freezing temperature of the water on the snow and ice making it melt and turn to water over again. On the other hand, the effectivity of rock salt becomes less when the temperature is below the freezing point. Also, the amount of rock salt matters a lot especially when ice and snows are thick, it requires a large amount of salt as well. The other factor that adds to its effectiveness is the pressure from the vehicles driving over the salted roads and streets. This implies that when the temperature decrease, more rock salts are needed to possible melt the targeted ice on the public areas as soon as possible.
