Performance Evaluation of Arizona’s LTPP SPS-2 Project: Strategic Study of Structural Factors for Rigid Pavements

As part of the Long Term Pavement Performance (LTPP) Program, Arizona Department of Transportation (ADOT) constructed 21 Specific Pavement Studies 2 (SPS-2) test sections on Interstate 10 near Buckeye, Arizona, to study a variety of structural sections in new portland cement concrete construction. Opened to traffic in 1994, this project is actively being monitored at regular intervals. Surface distress, profile, and deflection data collected throughout the life of the pavement were used to evaluate the performance of various rigid 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.
