Pavement management information system concepts, equations, and analysis models

This report describes the proposed modules of TxDOT's new Pavement Management Information System (PMIS) including: Utility Curves; Performance Curves; Needs Estimate Program; Optimization Program; and Impact Analysis Program. PMIS will use the pavement condition data currently being collected for the Pavement Evaluation System (PES). Distress, ride quality, deflection, and skid resistance data collection procedures and equipment will be retained, with only minor changes to the data collection frequency and section length. PMIS will provide network-level decision support for decision makers within TxDOT. PMIS will also support TxDOT pavement decisions at the Division, District, Area Office, and Maintenance Section level. Mainframe computers will be used at the central Division offices, while microcomputers will be used at the District offices to access and store the PMIS data. Eventually, PMIS will be able to support the use of microcomputers at the Area Office and Maintenance Section levels; for now, users in these Offices will be able to access the TxDOT mainframe computer to use PMIS.
