• 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.
