| 摘要： | 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. |
