Extending the Life of Highway Infrastructure: Summary of 2023 and 2025 TRB Data Workshops [summary report]

During the 2023 and 2025 Transportation Research Board (TRB) Annual Meetings, the Federal Highway Administration (FHWA) held two workshops that focused on using data to increase the longevity of the Nation’s pavement and bridge infrastructure. The primary objectives of the workshops were to highlight transportation data sources and how the data are being used by researchers around the country to perform analyses and develop practical tools to extend the life of highway infrastructure assets. The 2023 workshop discussed using available data to extend the life of highway infrastructure. Similarly, the 2025 workshop focused on the data that extend the lifecycle of highway infrastructure assets. More than 170 people—at least 50 in 2023 and 120 in 2025—participated in the two workshops. The workshops were sponsored by the TRB Infrastructure Group, three TRB sections, and 13 TRB standing committees. This document summarizes the key topics discussed at the two workshops.
