Effects of Additives in Deicing Salts at Lower Temperatures


Research is needed to evaluate and quantify the ability of additives to lower the eutectic point of deicing salt products. While some 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.


The goal of this project is to compare the eutectic points of various mixed salts to solid untreated white salt to determine how well mixed salt products perform at lower temperatures.

Expected Results

Research recommendations can be used to inform the decision-making of state departments of transportation, municipalities, and other winter maintenance practitioners when choosing a deicing salt for winter maintenance operations.
