Recent studies and field observations have confirmed that winter maintenance equipment that apply chemical deicers to the roads corrode at an accelerated rate. Roadway deicers usually feature chloride salts as their freezing‐point depressant. As such, exposure to roadway deicers poses a significant impact to highway maintenance equipment. The objectives of this chapter are to review practices available to manage the risk of deicer corrosion to equipment assets and to present some recommendations for the future research in this field. This scope includes the technologies available to mitigate the corrosion of metallic components, by enhancing the inherent corrosion resistance of the metal itself, altering the metal/electrolyte interface, or reducing the corrosivity of the service environment. This work concludes with a summary of the most common laboratory test methods used for the evaluation of the resistance of metallic components against corrosion, and recommendations for further research consisting of laboratory investigation and field validation to study the effectiveness of each type of corrosion‐prevention method.
