Arizona State and Local Government Documents Collection
The State and Local Arizona Documents (SALAD) collection contains documents published by the State of Arizona, its Counties, incorporated Cities or Towns, or affiliated Councils of Government; documents produced under the auspices of a state or local agency, board, commission or department, including reports made to these units; and Salt River Project, a licensed municipality. ASU is a primary collector of state publications and makes a concerted effort to acquire and catalog most materials published by state and local governmental agencies.
The ASU Digital Repository provides access to digital SALAD publications, however the ASU Libraries’ non-digitized Arizona documents can be searched through the ASU Libraries Catalog. For additional assistance, Ask A Government Documents Librarian.
Publications issued by the Morrison Institute for Public Programs at Arizona State University are also available in PRISM, in the Morrison Institute for Public Policy - Publications Archive collection.

Performance Evaluation of Arizona's LTPP SPS-6 Project: Strategic Study of Rehabilitation Techniques
As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation constructed 19 Specific Pavement Studies 6 (SPS‐6) test sections on Interstate 40 near Flagstaff. The SPS‐6 project studied the effect of specific rehabilitation treatments on jointed portland cement concrete pavement (JPCP) performance. The test sections had various JPCP surface preparations, including crack and seat, minimum and maximum restoration, rubblization, asphalt concrete (AC) with fabric, and asphalt rubber with conventional AC. Opened to traffic in 1991, the project was monitored at regular intervals until 2002. 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.
