Primary Topic: Pavement Maintenance Description: 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 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. Problems have been identified though that can definitely lead to early failures, such as mix design problems and reflective cracking problems. Even at this early point in the life of these rehabilitation strategies, differences in performance can be observed between treatments. With the continued monitoring of these sections, it is anticipated that the pavement community will continue to learn more and more about the performance of the various strategies and the effects of their design factors.
