Long-Term Pavement Performance Committee Letter Report: August 3, 2012

On August 3, 2012, TRB’s Long-Term Pavement Performance (LTPP) Committee sent its 30th letter report to Victor Mendez, administrator of the Federal Highway Administration (FHWA), and John Horsley, executive director of the American Association of State Highway and Transportation Officials (AASHTO). The committee's reports are aimed at supporting the further success of the LTPP program, securing the future of the LTPP database, and fulfilling the promise of better roads through the development and utilization of LTPP's products.

The report includes recommendations or requests for additional information related to the following: briefings of select AASHTO committees on LTPP’s data collection activities and the specific needs for continued state collaboration; the staffing, funding, and project plans for the continued operation of the LTPP product development and deployment activity; studying test sections of roadway immediately before they are retired from the LTPP studies; the addition of new experiments on warm-mix asphalt and pavement preservation into the LTPP test matrix; and the priorities of LTPP's ongoing activities of data collection, data analysis, and product development and delivery.
