On August 13, 2014, TRB’s Long-Term Pavement Performance (LTPP) Committee sent its 34th letter report to Gregory G. Nadeau, acting 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 to the FHWA and AASHTO 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 pertaining to the continuation of LTPP briefings to committees of AASHTO; development of contingency plans to define the technical activities that would be conducted by the LTPP program in the event of a reduction from MAP-21 levels in the funds available; conveying to the states and the public that LTPP is a continuing program with ongoing activities aimed at developing and delivering new products; the development and evaluation of a new traffic summary statistic; the plan for further development of InfoPave and the priorities by which the enhancements to be developed were determined; the development of a detailed plan for forensic studies of LTPP test sites at the conclusion of data collection at those sites, and a proactive approach for engaging state agencies in the review of this plan for forensic studies.
