• Abstract:
  The objective of this project was to develop a series of anti-icers tailored to meet the varying requirements of highway anti-icing performance, ; cost-effectiveness, and minimized corrosion and environmental impact for typical road weather scenarios and user priorities in the three ; ADOT&PF regions. Development and evaluation of potential deicing chemicals, additives, and mixtures made from local agricultural products or ; the by-products of local distilleries/breweries or other manufacturing processes for use on roadways and other transportation facilities were ; included as the project’s research. The use of sustainable resources offers a cost-effective alternative to high-cost proprietary products that ; enhance the performance characteristics of salt brine for anti-icing on Alaska roads. This research was accomplished through literature review, ; agency surveys, and laboratory investigation followed by field operational tests. Specifically, locally sourced salt brine additives suitable for anti-icing during winter maintenance in Alaska were developed and tested. ; Several test methods, such as differential scanning calorimetry, electrochemical impedance spectroscopy, and SHRP H205.2 Test Method for Ice ; Melting of Liquid Deicing Chemicals, were used to determine the performance of various anti-icing formulations relative to traditional sodium ; chloride (NaCl) and magnesium chloride (MgCl2) liquids. The negative effect of anti-icing formulations on bare steel and concrete were ; investigated to identify the most infrastructure-friendly anti-icing formulation
