• 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.
