Evaluating New Steel Coating Systems

Kentucky Transportation Cabinet's (KYTC's) Divisions of Bridge Maintenance and Structural Design have identified several steel coating systems that can reduce maintenance, lower project costs, and increase structure service lives. Candidates include thermal spray (metallizing), galvanizing, and novel one- and two-coat systems. Before KYTC adopts a coating system it must undergo accelerated weathering and corrosion testing. The industry standard for this testing is ASTM D5894. However, this standard calls for just 5,000 hours of testing. This project will expose candidate coating systems to 20,000 hours of accelerated weathering and corrosion testing to more accurately gauge their long-term performance in the field.
