ARIZONA AIRPORT PAVEMENT MANAGEMENT SYSTEM

The Aeronautics Division of the Arizona Department of Transportation (ADOT) is responsible for the funding of assistance for pavement projects at 56 primary airports throughout the state. In 1991 the department began the development of a network-level pavement management system. The development of the system, its functional parts, and the implementation of the system within the department are described. The development of the system included the marriage of existing Macintosh computer software for land use capability and noise studies for the airports with new software dealing with pavement deterioration and repair. The unique side of the development process was the need to formulate a system that could be used by all members of the Aeronautics Division during yearly 5010 safety inspections and produce meaningful prediction of pavement service life, rehabilitation requirements, and prioritization of pavement projects across the state. The Arizona Pavement Rating system uses a new pavement distress rating procedure to evaluate pavement condition. The system is based on experience gained from pavement evaluations that use pavement condition index procedures, but the system is not as labor-intensive and does not produce as much quantitative information. The development of this process is described, and its relationships to pavement condition index procedures are shown. The system calculates remaining service life and generates a prioritized project listing for each airport. The resultant project costs are combined into a statewide fiscal plan for funding requests. Software development and structure are described as are the links to the existing land use noise and 5010 data base software. The computer system and data base were installed in November 1992. Field training of ADOT users was completed during June and July 1992.
