A Methodology to Evaluate the Relative Performance of Various Coating Systems

In the U.S., bridge maintenance and rehabilitation cost billions of dollars annually, and corrosion is a major cause of bridge deterioration. Therefore, reducing corrosion is critical for bridge owners to save money as well as prevent bridge failures. Accelerated information on coating degradation rates during early stages of testing would be highly beneficial for making a bridge maintenance plan. A number of papers have been published to estimate the rate of coating degradation in terms of weight loss, film thickness reduction, surface blistering, surface rusting, and similar factors. However, no sensitive methods have been established for systematically comparing coating performance. This article discusses the various accelerated laboratory test methods that have been developed to predict a coating's field performance in a relatively short time. The full report that the article is based on appears in the online January 2009 edition of this publication.
