A new, all inclusive manual that incorporates Allowable Stress, Load Factor, and Load and Resistance Factor Rating methods into one publication. This manual provides guidelines for the procedures and policies for determining the physical condition, maintenance needs, and load capacity of highway bridges. Rating examples are also included. It has been developed to assist bridge owners in establishing inspection procedures and evaluation practices that meet the National Bridge Inspection Standards (NBIS). Supersedes both the Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges, 1st Edition and 2005 Interim, and the Manual for Condition Evaluation of Bridges, 2nd Edition with 2001 and 2003 Interim Revisions.
