Rehabilitation performance trends

This report documents the early observations from the Long-Term Pavement Performance (LTPP) Specific Pavement Studies (SPS) conducted as part of the LTPP Program Data Insight, which was conducted to identify initial findings from the test sections established for this program. Comparisons of performance trends were made to evaluate both the distinctions between the various rehabilitation treatments and the performance of the individual treatments themselves based on their condition prior to the treatment. Most of the rehabilitation strategies are still performing adequately after 3 to 4 years of service, as should be expected.
