Corrosion Concerns in Alaska to Personal and Commercial Vehicles Caused by Winter Operations Chlorides

The objective of this research effort was to synthesize relevant information on corrosion to Department of Transportation (DOT) equipment and vehicles caused by chloride-based deicing materials used in the state of Alaska. To accomplish this, a survey of Alaska Department of Transportation and Public Facilities (AKDOT & PF) personnel was used to identify deicers used and corrosion concerns. A literature review was conducted, and a synthesis document was developed that identified common corrosion issues and best management practices (BMPs) that can be used to prevent and or reduce corrosion. Fact sheets were developed to share information on corrosion concerns and BMPs that can be used to prevent and or reduce corrosion for both AKDOT & PF and the public. Identified best practices include using corrosion inhibitors in deicing products, washing equipment and vehicles as frequently as is feasible, following washing applying barrier protection when feasible, and conducting routine inspections of equipment and vehicles to report and initiate repairs of corrosion related damage.
