FHWA Releases Report on LTBP Research Priorities
In January 2013, FHWA released a new LTBP report outlining the workshops and discussions from its national conference, "FHWA Workshop to Identify Bridge Substructure Performance Issues."
With over 500,000 bridges across the country, the LTBP research mission focuses on collecting and analyzing quantitative data to better understand the critical factors that impact bridge performance. The two-day conference emphasized this mission, with sessions outlining research findings that could be applied to real-world bridge design and maintenance projects.
The two-day conference united engineers and decision-makers from across the nation. Brainstorming sessions and workshops on bridge performance provided useful input to the LTBP program and its research mission. These discussions identified feasible data needs like water table elevation and corrosion rates, quality control protocols, and geotechnical performance metrics.
Attendees also considered short-term and long-term LTBP research priorities, like approach interface issues, material degradation, and post-hazard event diagnostic tools. For a full agenda and report, download the FHWA report.
