Culvert Rating Guide
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 culverts current condition and are determined through analysis and engineering judgment by comparing the culvert structures capacity and dead load demand to live load demand.
