This study was conducted as part of the Federal Highway Administration’s (FHWA) Long-Term Bridge Performance (LTBP) Program. The LTBP Program is a minimum 20-year research effort, authorized by the U.S. Congress, to collect high- quality bridge data from a representative sample of highway bridges nationwide, that will help the bridge community better understand bridge deterioration and performance. The products from this program will be a collection of data-driven tools, including predictive and forecasting models that will enhance the abilities of bridge owners to optimize their management of bridges.
One of the first needs identified for LTBP Program development was to determine what specific bridge performance issues should be studied under the program. This would lead the way to identifying bridge data needs for the program, designing necessary data infrastructure, selecting bridges for the program, and designing effective experiments. This report documents the process used in the LTBP Program for identifying high priority bridge performance issues. Fifteen State departments of transportation participated in a series of focus group meetings and provided input on high priority bridge performance issues. Input was also solicited from the bridge community at large. The list of issues was periodically refined, evaluated, and described in detail. This report provides the results of that effort: 22 high-priority performance issues and a short list of six 6 issues that will be the initial focus of the LTBP Program. This report will be of interest to bridge program personnel from Federal, State, and local agencies as well as to parties engaged in bridge-related research and the practicing bridge engineering community.
