As part of the Long Term Pavement Performance (LTPP) Program, Arizona DOT constructed 16 SPS-1 test sections on U.S. Route 93 near Kingman. The SPS-1 study was designed to study a variety of structural sections in new asphalt concrete construction. Opened to traffic in 1993, the project was monitored at regular intervals until it was rehabilitated in 2006. 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 Arizona DOT.
