More chemicals are needed to prevent the initial formation of the ice-pavement bond. Anti-icing is being evaluated for use on high service pavements. To use it, you need accurate pavement condition forecasts to anticipate conditions where anti-icing will be effective. It may also require chemical and equipment types which are different from those used in traditional de-icing. Various ice control chemicals are being evaluated for anti-icing.
Experience shows that liquid chemical applications are more likely to succeed.
Liquid salt, magnesium chloride, calcium chloride, CMA, and potassium acetate are being evaluated. Pre- wetted dry chemicals may also prove effective. Studies during actual storm conditions show that anti-icing produces equal or better road conditions with less chemical use. These liquid chemicals remain on the pavement long enough to work. Several reports note residual effects for several days.
