• Abstract:
  As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation ; (ADOT) constructed 11 Specific Pavement Study‐5 (SPS‐5) test sections on Interstate 8 near Casa Grande. The ; SPS‐5 project studied a variety of different rehabilitation methods for asphalt concrete pavements. The ; project was opened to traffic in 1990 and monitored at regular intervals until it was placed out of study in ; 2009. Surface distress, profile, and deflection data collected throughout the life of the pavement were used ; to evaluate the performance of rehabilitation methods using unique combinations of minimal and intensive ; surface preparation, virgin and recycled asphalt, and thick and thin overlay thicknesses. This report ; documents the analyses conducted as well as practical findings and lessons learned that will be of interest to ; ADOT.
