| 摘要： | 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 projects 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. |
