Protecting Maintenance Equipment against Chloride Roadway Deicers: Corrosion Mechanisms, Test Methods, and Proactive Approaches
Roadway maintenance equipment in cold climates is exposed to high amounts of chloride-based deicers that are inherently corrosive. As such, various structural, hydraulic, and electrical components on maintenance equipment are vulnerable to the deleterious effects of chloride roadway deicers and their premature deterioration can negatively affect the performance, reliability and service life of the equipment fleet. This work aims to shed more light on this important asset management issue, by providing an overview of the relevant corrosion mechanisms, corrosion-prone parts, and test methods. More importantly, this work presents an overview of current approaches available to manage the risk of deicer corrosion to equipment assets, including design considerations, materials selection, and maintenance strategies. The information aims to enable equipment engineers and managers to gain a better understanding of this technical issue and to make more informed decisions in corrosion risk management.
