LTPP: THE NEXT DECADE

The Federal Highway Administration (FHWA) Long-Term Pavement Performance Program (LTPP) is the largest and most comprehensive pavement study in the world. In 1987, LTPP began a series of rigorous long-term field experiments monitoring more than 2,400 asphalt and portland cement concrete pavement test sections across the United States and Canada. Throughout its first decade, LTPP has furthered the understanding of how pavements perform. As it moves into its second decade, LTPP seeks to build on these efforts to further knowledge of why pavements perform as they do. To address this challenge, FHWA has developed a Strategic Analysis Plan that establishes a clear focus for analytical activities and data collection, launched a data resolution effort to address the gaps in data collected over the past several years, and initiated a monitoring adjustments effort.
