  • Abstract:
    All states are required to load rate and post bridges in order to comply with federal standards. Load ratings are performed in order to ; determine the safe live load capacity of a bridge, considering the existing conditions of the bridge. Based on the load ratings, the bridge ; is evaluated for load posting or strengthening. The Indiana Department of Transportation (INDOT) was notified that their practice for ; load rating and posting did not satisfy 23 CFR 650.313. The purpose of this study was to summarize and compare load rating and posting ; procedures used in other states and to provide recommendations and information necessary to modify the load rating and posting ; procedures in INDOT’s Bridge Inspection Manual (Part 3: Load Rating) in order to satisfy 23 CFR 650.313. ; In order to understand how load rating and posting is performed in other states, department of transportation (DOT) manuals were ; examined, questionnaires were sent to states, and additional states of interest were surveyed. The American Association of State ; Highway and Transportation Officials (AASHTO) The Manual for Bridge Evaluation, Second Edition, which is the current specification for ; load rating and posting bridges was reviewed, as well as older AASHTO bridge evaluation manuals. Based on this information, revisions ; were proposed to the INDOT Bridge Inspection Manual (Part 3: Load Rating) in order to eliminate current deficiencies.
