Long-Term Bridge Performance Committee Letter Report: February 20, 2015

View Cover




On February 20, 2015, TRB’s Long-Term Bridge Performance (LTBP) Committee sent its fifth letter report to Gregory Nadeau, acting administrator of the Federal Highway Administration (FHWA). The committee provides advice and assistance on the conduct of the LTBP program, which is designed to collect research-quality data on a large representative sample of in-service U.S. highway bridges and to analyze these data to improve understanding of the mechanisms and timing of bridge deterioration due to the effects of age, materials, traffic, and weather.

The report includes recommendations related to the provision of additional or amplified responses to the LTBP Committee’s recommendations, and status reports on follow-up actions; anticipation of the use by others of tools developed to facilitate LTBP research; the development of expository white papers describing LTBP’s use of deterioration models, weathering of steel bridges, and a glossary of commonly used terms; the revised timing and content of status reports on LTBP progress; committee participation in LTBP State Coordinators meetings; the improved balance of the program’s shorter-term issue-driven investigations with longer-term research activities; and the development of a business plan based on available funding and staffing.
