Abstract: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.
