Structural Evaluation and Short-term Performance of Sustainable Pavement Sections at the NCAT Pavement Test Track

---

As state agencies have started to transition from an empirical pavement design method to a Mechanistic-Empirical (ME) approach, it has become necessary to further evaluate the material properties and structural characteristics of newer sustainable pavement technologies. The objective of this study was to evaluate pavement responses and short-term performance for different sustainable pavement sections placed at the National Center for Asphalt Technology (NCAT) Test Track. The Test Track was reconstructed in the summer of 2009 and part of the experiment included six new structural sections built using several sustainable technologies. Falling Weight Deflectometer (FWD) testing and strain and pressure measurements under live traffic loads were obtained periodically under different environmental conditions. Results indicated that pavement responses changed significantly for some sustainable sections. Field performance measurements showed that rut depths were influenced by the use of sustainable technologies, but all sections performed well overall with less than10 mm of rutting. No cracking had been observed in any of the sections after 20 months of operation and over8 million applied EASLs.
