• Abstract:
  The purpose of this Culvert Rating Guide is to present a clear, repeatable and valid procedure for Texas ; Department of Transportation (TxDOT) engineers and their consultants to use for load rating culverts in the TxDOT ; roadway system. ; The American Association of State Highway and Transportation Officials (AASHTO) defines “load rating” as the ; maximum truck tractor tonnage, expressed in terms of HS load designation, permitted across a bridge culvert. ; The load rating is expressed in terms of two separate ratings – an Inventory Rating and an Operating Rating. The ; Inventory Rating (IR) is the maximum truck load that can safely utilize the bridge or culvert for an indefinite ; period of time (AASHTO, 2003; TxDOT, 2002). The Operating Rating (OR) is the absolute maximum permissible ; truck load that may use the bridge culvert. Load ratings are based on the culvert’s current condition and are ; determined through analysis and engineering judgment by comparing the culvert structure’s capacity and dead ; load demand to live load demand.
