TSP Research Roadmap

Overview

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. ]

The TSP Research Roadmap - January 2008

Research Roadmap Survey

Provide your input on the proposed TSP Research Roadmap Problem Statements (see details below) by participating in the Research Roadmap Survey. The purpose of this survey, is to gauge the level of interest in each of the research topics comprising the roadmap, and to ascertain whether preservation practitioners or organizations would be interested in providing technical and/or financial support to any of the proposed efforts.
