David Krepps asks "Can the de-icing solution ever freeze on the roads?"
In short, no, brine will not freeze, at least not around here.
Area road crews almost always use a brine mixture, and in many cases, they actually mix it up themselves. It's made up of rock salt and water, and when combined in the right way with the right percentages, authorities say they can pretty much promise it won't freeze even in the coldest East Tennessee temperatures.
Here's basically what brine does: the liquid dries on the asphalt, then it becomes a salty surface on that asphalt, and when the snow or ice comes, the brine creates almost a lubricant that prevents bonding of ice or snow in the future.
