The article describes a 4-year observation of calcium magnesium acetate deicers that shows that the product is a viable alternative to salt in some situations, if used correctly. When mixed with snow, CMA becomes hydrated, gaining water as it dissolves. This action inhibits snow particles adhering to each other or to the road. This snow remains light and dry compared to the heavier, slushy snow created by the salt's briming action. CMA stops working at about 10 deg F, while salt stops at 20 deg F. The lower free-water content of CMA-treated snow explains how CMA helps prevent refreezing and pack formation at lower temperatures. The reasons why CMA performs well in the field but is judged marginal in laboratory tests are discussed. The storage and handling requirements of CMA are discussed.
