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.

Over the past 15 years, the Phoenix-Mesa Gateway Airport has been in a continual planning and development program, responding to the dynamic air travel market in the Phoenix metropolitan area. A study was done to develop a phased, revenue generating land use and ground transportation plan for an approximate 660 acre parcel, with an adjoining 31 acre privately-owned parcel, both located in the Northeast Area of the Airport. This report presents the analysis, findings, and recommendations in support of those objectives.

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.

The Ganado-Burnside Area is a rural community located on the Navajo Nation in northeastern Arizona. Ganado was formally established in 1901 as the location for a Presbyterian Church Mission, a school and hospital. Later the community served as a center to distribute various types of Bureau of Indian Affairs services. Today, the community area serves as a major center for housing, education, health and government operations. Also in the Burnside area, the Ganado School District recently established a new high school and sports venue to accommodate track and field, baseball, and basketball activities.

There are four main roadway corridors that intersect the study area: State Route 264, US Route 191, Navajo Route 27 and Navajo Route 15. There are also county gravel roads and private and community dirt roads that intersect SR 264, the main traffic corridor. Within these routes there is substantial multimodal activity generated from the area schools, medical facilities, transit operations, government entities, utility providers and social programs. The principal focus of this study project is to address the most critical transportation planning needs identified by the Ganado Chapter and Apache County. This will include, but is not limited to, a comprehensive needs analysis of multimodal movements and traffic circulation as well as safety issues for the project area corridors. The major product of the study will be a final report, which contains a Plan for Improvements. Taking into consideration received public input, the Plan will span over five-, 10- and 20-year periods, incorporating both roadways and the multimodal needs of the area.

The Ganado-Burnside Area Traffic Circulation Study will also be conducted according to a cooperative planning process that involves stakeholders that include public agency staff, elected tribal officials and tribal community members. Throughout the study, information will be presented to and solicited from stakeholders through individual interviews and to the general public through public meetings and other means of communication.

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).
