Once there is an accumulation of precipitation, you may also see salt trucks spreading hard rock salt over snowy and icy roads. So why do they do this? Why does salt melt ice and snow? Salt causes a phenomenon called freezing point depression, which means it lowers the freezing point of water.
Why don’t they put salt crystals on the roads anymore?
The agency has since reduced using salt crystals, which are less effective because they can bounce off the road, and are more likely to damage the environment. Now they use a sand-salt mixture and pre-treat roads with a mixture of water and salt that prevents freezing.
Why don’t they put salt on roads to melt ice?
If the temperature of the roadway is lower than about 15 degrees F (- 9 C), the salt won’t have any effect on the ice. The solid salt simply can’t get into the structure of the frozen water to start the dissolving process. In these cases, the DOT typically spreads sand on top of the ice to provide traction.
