Effects of Additives in Deicing Salts at Lower Temperatures – RE-POST

Brief description: MnDOT requests responses for a Clear Roads project that will evaluate and quantify the ability of additives to lower the eutectic point of deicing salt products. While manufacturers of deicing salt products claim that additives enhance product performance, there is no definitive evidence to substantiate these claims. Evaluating these products in the lab will establish the effectiveness of additives to lower eutectic temperatures and will indicate whether additives increase the performance of deicing salts. Research recommendations can be used to inform the decision-making of state departments of transportation (DOTs), municipalities and other winter maintenance practitioners when choosing a deicing salt for winter maintenance operations.
