• Abstract:
  The Federal Highway Administration technical advisory (TA) 5140.22, Uncoated Weathering Steel in Structures, issued on October 3, 1989, gave broad guidance to bridge owners on the use of uncoated weathering steel (UWS), covering environments where UWS should be used with caution and detailing guidance. This guidance was mainly qualitative, which is largely adequate for detailing guidance, but quantitative guidance on environments of concern is needed to achieve consistently good performance of UWS bridges. Researchers for this study addressed this need through two parallel efforts: a field evaluation program of bridges, accompanied by laboratory analysis of field samples, selected using a statistically driven process, and a statistical analysis of the performance and associated environments of all known UWS bridges in the United States. As a result, the researchers provided quantitative recommendations for two environments of concern: coastal environments, as well as highway overpasses with heavy deicing agent use on the underpassing roadway.
