Effects of Deicing/Anti‐Icing Chemicals (DIAICs) on Rubberized Asphalt Pavements

The objective of this study was to evaluate the effect of typical chemical winter maintenance practices on Arizona Department of Transportation (ADOT) pavements. A review of previous studies on the effect of deicing/anti‐icing chemicals (DIAICs) did not yield definitive recommendations, especially for DIAICs typically used by ADOT. Researchers conducted a laboratory study evaluating the effects of magnesium chloride, potassium chloride, sodium chloride, and distilled water on eight different open‐graded rubber‐modified asphalt concrete mixes using the boiling test (ASTM D3625). All experimental factors were found to be statistically significant, and the researchers provide recommendations on which DIAICs should be used for different binder and aggregate types.
