This is an 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. This manual has been developed to assist bridge owners by establishing inspection procedures and evaluation practices that meet the National Bridge Inspection Standards. The manual is divided into eight sections, each representing a distinct phase of an overall bridge inspection and evaluation program. This manual replaces both the 1998 AASHTO Manual for Condition Evaluation of Bridges and the 2003 AASHTO Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges. It also supersedes the Manual for Bridge Evaluation, 1st Edition with Interims. It serves as a single standard for the evaluation of highway bridges of all types.
Included in this electronic edition are the 2011 and 2013 Interim Revisions. Following each chapter the Revisions are identified as well as linked throughout the entire book where available. See the "Interim Revisions 2011 and 2013" sections for a complete list of changes to each section.
