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.

As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation constructed eight Specific Pavement Studies 9 (SPS‐9) test sections on Interstate 10 near Phoenix is an overlay project and is accordingly given independent analysis and documentation in this report separate from Arizona SPS‐9B projects 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.

To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews

To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews the effect of five alternative permit strategies on the County's ability to preserve unfragmented landscapes through conserving ranch lands.
