Identification and Laboratory Assessment of Best Practices to Protect DOT Equipment from the Corrosive Effect of Chemical Deicers

Description: This study has identified, evaluated and synthesized the best practices that can be implemented to minimize the corrosive effects of chloride deicers on DOT winter application equipment and vehicles. The practices identified include: design improvements, maintenance practices, anti-corrosion coatings, corrosion inhibitors, salt removers, etc. A comprehensive literature search was conducted to gather existing research documents that are relevant to the corrosion of metals by chloride salts, with a focus on corrosion under neutral pH conditions and under ambient temperature and pressure. A nationwide survey was conducted of stakeholder groups, in order to capture the current knowledge in: estimating the deicer corrosion costs to vehicles and equipment, defining the chloride deicer corrosion problem and identifying best practices or products for managing the problem.
