• Abstract:
  As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation(ADOT) constructed 36 Specific Pavement Study-3 (SPS-3) test sections across four test sites in Arizona. The purpose of the SPS-3 experiment was to study various maintenance strategies for asphalt concrete (AC)pavements. Using surface distress and profile data collected throughout the life of the test sections, investigators evaluated the performance of four AC pavement maintenance strategies: thin overlay, slurry seal, crack seal, and chip seal. This report documents the analyses conducted as well as practical findings and lessons learned that will be of interest to ADOT.
