NTIS Accession No. of the report covered in this TechBrief: PB2014-106340

This research 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 to collect scientific performance field data, from a representative sample of bridges nationwide, that will help the bridge community better understand bridge deterioration and performance. It will be a collection of data-driven tools including predictive and forecasting models that will enhance the ability of bridge owners to optimize their management of bridges.

Objective

The objective of this TechBrief is to describe the bridge performance issues that will be studied under the LTBP Program, including how they were identified and prioritized with the assistance of bridge owners and other key stakeholders in the bridge community. It is intended for bridge owners and the bridge community at large (i.e., bridge engineers, bridge inspectors, and bridge asset managers) interested in the activities of the LTBP Program.
