The FHWA in partnership with the American Association of State Highway Transportation Officials (AASHTO) and the preservation industry, have sponsored a study to delineate the most critical knowledge gaps in pavement and bridge preservation and the research which is necessary to fill those gaps. This Transportation System Preservation (TSP) Research, Development, and Implementation Roadmap is the output of that partnership effort, and was compiled via input received during three (3) regional workshops conducted in 2007. 

Working together with preservation practitioners from State, Provincial, and local transportation agencies; industry, academia, and the FHWA; this effort has resulted in the development of a broad array of pavement and bridge preservation research needs statements which comprise the "TSP Research Roadmap," now available for download below. 

[ Note: For detailed research needs statements, please refer to the Roadmap report appendices. ]
