Bridge coatings are the primary means of corrosion protection for steel bridges in the United States. Most bridge coatings tend to fail prematurely in localized areas and spot painting can be used restore the lost corrosion protection and extend the service lives of existing bridge coatings, often at a fraction of the cost of a complete bridge repainting. However, many state highway agencies do not perform spot painting primarily due to performance concerns and lack of familiarity with its proper utilization and execution. The research overview is accompanied by NCHRP Web-Only Document 251: Volume 1: Guidance. ER -
