Txdot Project 0 6955

Images of slides presented at a Texas Department of Transportation workshop. Includes findings of a three-part study (Project 0-6955) performed by the Texas A&M Transportation Institute in cooperation with the Texas Department of Transportation and the Federal Highway Administration. In this study, strategies were developed to reduce uncertainty in load rating procedures to potentially remove the load postings of typical steel and concrete bridges in Texas that are posted at load levels below the legal limit. The presentation outlines several aproaches for reviewing load postings for steel and concrete bridges using refined methods, and discusses model updating, and impact of the methods on rating factors. The presentation ends with refined load rating guidelines that were developed from this study, along with load rating examples, and recommendations.
