Abstract:

The Federal Highway Administration 100-Year Coating Study was initiated in August 2009 to search for durable ; coating systems at a reasonable cost. The objective of the study was to identify and evaluate coating materials that can ; provide 100 years of virtually maintenance-free service life for steel bridges. Selected coating systems included three ; three-coat systems, four two-coat systems, and a single-coat system of high-ratio calcium sulfonate alkyd. All coating ; systems were evaluated under accelerated laboratory testing and three outdoor exposure conditions, namely natural ; weathering and natural weathering with salt spray in McLean, VA, and outdoor testing at the Golden Gate Bridge in ; San Francisco, CA. One design innovation was the employment of 18- by 18-inch large test panels that contained ; welding joints and angle attachments using bolts and nuts to closely simulate realistic conditions that are encountered in ; bridges in the field. This report presents results of performance evaluation of the eight coating systems.
