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.

| 16. Abstract
Bridge performance is a multifaceted issue involving performance of materials and protective systems, performance of individual components of the bridge, and performance of the structural system as a whole. The Long-Term Bridge Performance (LTBP) Program was initiated to collect, store, and analyze the data necessary to better understand high priority bridge performance issues. The success of the program depends on first being able to identify the most important performance issues bridge owners face. To identify these issues, input from those bridge owners and other key stakeholders was sought. As part of this outreach, bridge experts in 15 State transportation departments were interviewed and asked to name the performance issues in their bridge inventory that are most common and/or most difficult to solve. The findings of these interviews are included in this report. To supplement these interviews and identify high priority issues related to bridge substructures, a workshop on substructure performance issues was held. The findings from the interviews and the substructure workshop were used to develop a list of 22 high priority performance issues. From this list, a shorter list of six bridge performance issues was recommended as the first group of issues for study under the LTBP Program. |
