| Abstract | The purpose of this reference guide is to provide guidelines for load rating the nation’s highway tunnels to meet the regulatory requirements and to ensure consistency and uniformity of load rating those tunnels. This reference guide provides technical aspects for the load rating of tunnel structures that meets FHWA’s general load rating guidance and provides practical, representative step-by-step examples. This reference guide provides technical details and breadth appropriate for explaining the load rating specifications and guidelines governing United States highway tunnel structures, namely the American AASHTO Manual for Bridge Evaluation and the FHWA Tunnel Operations, Maintenance, Inspection, and Evaluation Manual. This reference guide is applicable to structural components of tunnels that support roadway live loads, including invert slabs, walls, and other supporting members as well as tunnel liners where applicable, that support live load from nearby highways, and provides guidance on evaluating member loads and resistances for the development of load ratings; determining posting ratings or restrictions as necessary; and issuing permits. |
