This study was conducted as part of the Federal Highway Administration’s Long-Term Bridge Performance (LTBP) Program. The LTBP Program is a long-term research effort, authorized by the U.S. Congress under The Safe, Accountable, Flexible, Efficient Transportation Equity Act legislation, to collect high-quality bridge data from a representative sample of highway bridges nationwide that will help the bridge community to better understand bridge performance. This report reviews the state-of-the-art with respect to bridge condition indices being used to assess performance of bridges in the United States and other countries. This report should be of interest to bridge program personnel from Federal, State, and local transportation departments as well as to parties engaged in bridge-related research.

| 16. Abstract
Bridge performance measures are important components of any successful Bridge Management System. Different types of performance measures have been developed for various purposes. The types of performance measures are usually a reflection of an agency’s goals. The bridge health or condition index is a type of performance measure used by agencies interested in preserving the condition of bridge structures. Bridge condition index is very attractive because it provides a single index for assessment of the structural and or functional health of a bridge based on the condition of the bridge’s structural elements and the services provided by the bridge. As outlined in the FHWA’s Long-Term Bridge Performance Program, the development of condition indices should be driven by more objective and quantitative data to help bridge managers make informed decisions. This work reviews the state-of-the-art with respect to bridge condition indices being used to assess performance of bridges in the United States and other countries. |
