Why brine and not just plain salt?
Simply put, mixing rock salt with water and applying it that way gets more bang for the buck. Tina Greenfield, with the Iowa Department of Transportation’s Office of Maintenance, said, “More often than not, we just brine to treat the roads, instead of using salt alone. There’s nothing magical about brine. It’s simply a mixture of salt and water. When the water evaporates, it leaves a film of salt that says on the road.”
