LTPP PROGRAM NOW MORE COMPLETE

Having complete data from a broad sample of pavement test sections is essential to the success of the Federal Highway Administration's (FHWA) Long-Term Pavement Performance (LTPP) program. To this end, a data resolution effort was initiated in 1997 as the LTPP program entered its second decade. The goal of the data resolution effort has been to obtain complete data sets from as many of the program's pavement test sections as possible. Overall, the effort has been a great success, with a 15% increase in the amount of data available for analysis. However, a shortfall still exists in the areas of monitored traffic volume and weight data for the Specific Pavement Study sections. The next step in the data resolution effort is to review the data in order to adjust the monitoring schedules for the test sites. The new monitoring schedules place the data collection emphasis on those sections that can best contribute to the development of improved pavement technologies from the LTPP data, while optimizing the resources of the states, provinces, and FHWA.
