Best Practices for the Prevention of Corrosion to DOT Equipment: A User’s Manual


Corrosion to maintenance equipment resulting from the use of chloride deicers is a challenge for transportation agencies across North America. While there are many products and much anecdotal guidance for the prevention of corrosion, there is not a consolidated guide that combines all of the available knowledge on corrosion prevention for use by snow and ice control practitioners. Such a manual could aid the entire winter maintenance community in the prevention of corrosion and the extension of equipment life.

In the 2013 final report for the project on Best Practices and Guidelines for Protecting DOT Equipment from the Corrosive Effect of Chemical Deicers, the researchers identified the need for additional study to bridge existing knowledge gaps relevant to this subject. This includes research on the long-term effectiveness of practices or products for corrosion protection; minimizing the risk of premature failure of the post-assembly coatings; the synergistic use of washing and inhibitors; and the study of metallic components. Finally, research is needed to develop guidelines on the best practices for preventing deicer corrosion.


This goal of this project was to develop guidelines for corrosion management on highway maintenance equipment.


A guide that summarizes in layman’s terms the best practices to prevent corrosion to maintenance equipment.
