Development of a Comprehensive Plan to Enhance ADOT's Pavement Management Forecasting and Decision Making Capability

As the Department of Transportation approaches the second decade of this century, it is clear that the implementation of significant improvements in project development and system preservation are mandatory. Historically, improvements to transportation infrastructure have directly correlated with improvements to the Local, State and National economy. To maximize asset management; to facilitate pavement design and pavement preservation; and to precisely target highway infrastructure improvements, it is critical that the Department enhance its Pavement Management cross-functional interconnectivity. The Pavement Management Section lacks the ability to support the Materials Group's new Mechanistic-Empirical Pavement Design Guide. Designers are unable to access critical information concerning pavement condition, including the extent of traffic exposure, and the type and extent of cracking. In addition, there is no existing provision that facilitates updating and distribution of critical data to the Engineering Districts. This research is expected to provide software with real time access to pavement condition and design data on a state-wide basis, in a manner that can be readily used by Highway Development and Engineering District personnel. Implementation is expected to result in lower costs to develop highway design strategies. Even more importantly, it is expected to lower costs for the construction and maintenance of the State's highways throughout their lifecycle. This project includes the following tasks: (1) Review the Department's current Pavement Management System interdisciplinary data sharing functionality. (2) Identify the critical connectivity nodes and determine the relative strength or weakness of their ability to transfer the appropriate data. (3) Evaluate the performance of extant alternative systems to determine their potential to enhance the Pavement Management Section's link to Arizona Department of Transportation's (ADOT's) maintenance systems, the bridge systems, and the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide requirements. (4) Implement a functional web based database that is compatible with these research objectives, and will monitor the Pavement Management organization's network optimization and interdisciplinary connectivity.
