Bridge Coating Performance: Two-Coat vs. Three-Coat Systems

In this article, the author describes the results of the Maryland State Highway Administrator (MHA)’s performance evaluation of coating systems. MHA’s performance tests compared 2 two-coat paint systems against the standard three-coat system used on Maryland bridges in order to determine which system would provide the most protective and cost-effective bridge rehabilitation. In addition to the coating systems, the processes of bridge selection, abrasive blast cleaning, testing and visual inspection are described. The study showed the two-coat system to be less cost-effective than the three-coat system when tested over blast-cleaned surfaces, and the three-coat system was determined to be the best performing paint system according to this research.
