• Abstract:
  As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation (ADOT) ; constructed eight Specific Pavement Studies 9 (SPS‐9) test sections on Interstate 10 near Phoenix (04B900). SPS‐9A ; 04B900 is an overlay project and is accordingly given independent analysis and documentation in this report separate ; from Arizona SPS‐9B projects (040900 and 04A900) located on US 93, which were new construction and are ; documented in a separate report. The SPS‐9A project studied the effect of asphalt specification and mix designs on ; flexible pavements, specifically comparing Superpave binders with commonly used agency binders. Opened to traffic in ; 1995, the project was monitored at regular intervals until it was rehabilitated in 2005. 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.
