Verification of Performance Prediction Models and Development of Data Base Phase II Arizona Pavement Management System

摘要

A pavement management system (PMS) has been defined as 'the systematic development of information and procedures in optimizing the design and maintenance of pavements' (1) The purpose of this research was to verify and adjust models (equations) developed in phase I, II, and III of the PMS. This verification process involved testing models against real data and determining the correlation. Appropriate adjustments were made to enhance the final predictions. Results of this work indicate that the prediction models can reasonably predict the future ride and cracking condition for newly constructed, in-service and overlaid asphaltic concrete pavements, as well as, plain concrete pavements. The second purpose of this project was to develop a PMS data base. The data base contains over 250,000 records which are stored in an information management system (IMS) file. Data is stored hierarchially which facilitates the retrieval of data via a remote terminal. Computer programs which allow various users (Designers, Maintenance Engineers, District staff, Researchers, Planners and others) to retrieve data in less than one minute have been implemented and have been in use for six months within the department.
