On February 12, 2013, TRB’s Long-Term Pavement Performance (LTPP) Committee sent its 31st letter report to Victor Mendez, administrator of the Federal Highway Administration (FHWA), and Frederick G. “Bud” Wright, 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 facilitating the fulfillment of the program’s 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: the process for identifying and selecting LTPP products for future development; forensic analysis of mature LTPP test sections; the plans and funding of new warm mix asphalt and pavement preservation experiments; the distinction between pavement maintenance and pavement preservation experiments; potential reorganization of the expert task groups; and the development of new products in the traffic data and analysis area.
