Coating Performance on Existing Steel Bridge Superstructures

Publication Information

Publication Type:
Report
Publication Number:
FHWA-HRT-20-065
Abstract:

This report documents a study that evaluated the corrosion protection performance of four coating systems applied to steel substrates with various chloride contamination levels. The purpose of the study was to identify coating systems that can provide extended service life for steel bridges with minimal surface preparation. This study helps estimate the amount of chloride contamination that coating systems can tolerate without premature failure. Owners, consultants, contractors, and technical experts interested in the durability of coatings applied to contaminated steel substrates may benefit from the information contained herein
