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 purpose of this report is to provide information concerning deaths from exposure to heat due to weather conditions occurring in Arizona. Unlike our other reports, designed to monitor health status of the residents of Arizona, this publication is focused on mortality occurring in the State to both residents and non-residents. The data for 2002 (the latest year with complete information) are placed in a temporal context by comparison with the data for the preceding ten years.

In "Roadmap to Arizona's Economic Recovery," a general fund revenue forecast is presented which includes proposed changes to the revenue system. If the proposed changes are backed out of these figures, the baseline forecast can be obtained. This addendum provides detail on the Roadmap's revenue projection. the three key points are: 1) Arizona's economy is highly cyclical, growing much faster than the nation during economic expansions; 2) Revenues everywhere, but especially in Arizona, given its revenue structure, are much more cyclical than the overall economy; 3) the revenue forecast in the Roadmap is actually conservative. Revenues relative to the size of the economy remain below the historical norm, even in fiscal year 2015.

The state government general fund shortfall in the current fiscal year is projected to be between about $550 million and $1 billion. This shortfall will need to be eliminated through spending cuts and/or revenue enhancements. The Legislature has demonstrated a preference for spending cuts. However demand does not decline during a recession for most public-sector services, including university services. Any reduction in funding for universities will have a negative and direct effect. A reduction in state government spending for universities of around $200 million would cause direct and indirect job losses of approximately 4,000. A substantial decrease in state government funding for universities will have negative consequences beyond these short-term effects.

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).
