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).

"This guidelines and procedures manual is intended to be used by the staff of the Arizona Department of Transportation (ADOT) and Arizona's regional transportation planning agencies, which include Councils of Governments (COGs), Metropolitan Planning Organizations (MPOs), and Transportation Management Areas (TMAs). In addition to outlining the guidelines and procedures for regional transportation planning functions, this manual provides an overview of the programs administered by the ADOT Multimodal Planning Division (MPD)."--Introduction, Page 1-1

"The Hopi Senom Transit Program has been operating for the past twenty-two years to provide public transportation on the Hopi Reservation and local border towns to the general public and employees of local governmental and private sector agencies. The service area includes the Hopi and Navajo reservation areas and Flagstaff. Boundaries and major communities of the area served is Keams Canyon, Tuba City, Flagstaff, Leupp and Kykotsmovi. Currently, the Hopi Senom Transit Program operates two fixed routes providing service five days a week. Service is provided on schedule between Kykotsmovi and Moencopi, and Kykotsmovi and Keams Canyon. Vanpool transportation for Tribe employees is provided Monday through Thursday between Flagstaff and Kykotsmovi. This vanpool style service is open to the general public, but is used primarily by Tribe employees. The Public Transportation Section of the Multimodal Planning Division of the Arizona Department of Transportation is charged, among other roles, with administering transit programs including the Section 5311 Rural Transit Program ... The Five-Year Implementation Plan will provide a roadmap for transit services on the Hopi Reservation. In addition, a matrix of tasks and responsibilities will provide a framework for the Section 5311 Program to maintain management oversight of the rural transportation programs. This framework will become a key part of the evaluation process for future funding cycles"--Pages 1-2

The Multimodal Planning Division (MPD) of the Arizona Department of Transportation has been tasked with identifying corridors throughout the state where improvements to the transportation infrastructure supports the greatest potential commercial and economic benefits. These "Key Commerce Corridors" represent a strategic statewide approach to leverage infrastructure improvements to enhance Arizona's competitive economic position. This document presents the basis for the identification and evaluation of the Key Commerce Corridors.

There are many factors that affect the durability of Portland cement concrete (PCC), including the mix design and the materials used, the quality of construction, and the environment. Durability is not an intrinsic property of the concrete, but instead is related to how the material interacts with the environment. Durability-related deterioration is referred to as materials-related distress (MRD). Common MRDs include those caused by physical processes, such as freezing and thawing, or chemical processes, such as alkali-silica reactivity (ASR) and sulfate attack. This research project was undertaken to determine whether concrete used in the ADOT system is experiencing, or is potentially susceptible to, ASR or sulfate attack, and if so, to what degree.
