Performance Evaluation of Arizona’s LTPP SPS‐6 Project: Strategic Study of Rehabilitation Techniques

As part of the Long Term Pavement Performance (LTTP) Program, the Arizona Department of Transportation (ADOT) constructed 19 Specific Pavement Studies 6 (SPS-6) test sections on Interstate 40 near Flagstaff. The SPS-6 project studied the effect of specific rehabilitation treatments on jointed portland cement concrete pavement (JPCP) performance. The test sections had various JPCP surface preparations, including crack and seat, minimum and maximum restoration, rubblization, asphalt concrete (AC) with fabric, and asphalt rubber with conventional AC. Opened to traffic in 1991, the project was monitored at regular intervals until 2002. Surface distress, profile, and deflection data collected throughout the life of the pavement were used to evaluate the performance of various flexible pavement design features, layer configurations, and thickness. This report documents the analyses conducted as well as practical findings and lessons learned that will be of interest to ADOT.
