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.
The 2016 College Football Playoff National Championship Game was held on January 11, 2016, in Glendale, Arizona. The W. P. Carey School of Business at Arizona State University was commissioned to conduct an economic impact assessment of the Game and events surrounding it, including the impact of direct and indirect visitor and organizational expenditures. This study utilized multiple research, survey and analytical methodologies. This report will outline the methodologies used and the results obtained in the study and the economic impact.
This study examines the economic impact of the Central Arizona Project (CAP) to the State of Arizona in two aspects: the construction of CAP, 1973‐1993; and the impact of CAP's water supply delivery operations, 1986‐2010. A modified IMPLAN input‐output model for the State of Arizona is used to implement both analyses. The economic impacts for each analysis are assessed in terms of gross state product (GSP) and employment.
Under contract HFR-PL-1(31)264, "Concrete Pavement Design and Rehabilitation," a comprehensive data base was created which contains pavement design and construction data, climatic information, traffic data, and condition data for 48 pavement sections. The data base includes projects from jointed concrete pavements (40 sections), prestressed concrete pavements (4 sections), continuousIy reinforced concrete pavements (2 sections), and 3-layer structural rehabilitation pavements (2 sections).
