Ensuring the safety of motorists and passability of roadways in the winter months is critical in many regions of the country. Some of the most useful parts of the toolkit many municipalities use to ensure roadway safety are deicing chemicals such as granular rock salt, salt brine, magnesium chloride, or calcium chloride. These chemicals function by effectively lowering the freezing point of water. Deicers can be used before a storm to prevent snow and ice from bonding as solidly to pavement and improve the effectiveness of plowing. Typically, this is called “anti-icing” and brine's are predominantly used in this capacity.
