On August 3, 2012, TRB’s Long-Term Bridge Performance (LTBP) Committee sent its second letter report to Victor Mendez, 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 dissemination of information about the LTBP program, types of bridges to be included, and issues of data collection and measurement.
