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.
