A benchmark survey was conducted by MAG and ADOT in December of 2006 to determine initial attitudes and awareness of litter issues in Arizona and to evaluate littering behavior. A follow-up survey was then conducted in July 2008, at the end of the first two years of the campaign, to determine if any changes in awareness, attitudes or behavior were realized. Subsequent follow-up studies focused on Maricopa County residents.

This report documents the efforts of the Arizona Department of Transportation to implement the American Association of State Highway and Transportation Officials DARWin‐ME pavement design and rehabilitation guide. As part of this implementation, the research team also prepared a practical stand‐alone user’s guide that provides guidance for obtaining inputs, conducting design, and establishing the recommended pavement design.
