This report summarizes the current status of the Long-Term Pavement Performance (LTPP) program and its major activities-data collection, data storage, data analysis, and product development. It describes the work that will be needed beyond 2009 to realize the full potential of the world's most comprehensive pavement performance database and the benefits that will be accrued by capitalizing on the investment that has been made. The work that remains is as follows: (1) Provide ongoing security and maintenance of the LTPP database and manage the Materials Reference Library (MRL). (2) Continue to support LTPP database users. (3) Further develop the LTPP database including additional data collection and database refinements and (4) Continue data analysis and product development. |
