  • Abstract:
    Tennessee Department of Transportation (TDOT) established Pavement Management System (PMS) since 1980’s. TDOT started to systematically collect roughness data since 1993 and distress data since 1998 and started using videotaping from 2002. Similar to many other agencies in the United States, TDOT utilized PMS to perform maintenance demand analysis based on which the budget allocation is determined. Furthermore, cost- effectiveness analysis of maintenance activities or preventative maintenance, prediction analysis of long-term pavement performance, and calibration of pavement design equations are conducted based on the content and accuracy of PMS data. The purpose of this research is to identify the current quality issues of PMS data and to establish the data quality management guideline by which a standard data production procedure can be followed. The summary of results are as follows. Findings from the questionnaire indicated field validation/calibration of testing equipment is considered as the most selected steps before data collection. The survey also indicated that although some state DOTs have already implemented or have been developing data quality control procedure, there is no consensus on how to perform data quality control and assurance. The research team also systematically evaluated the data variability and its consequence on maintenance planning. The influence of data quality on maintenance planning varies in terms of current pavement conditions, how the pavement condition indices are defined, and how the maintenance and rehabilitation analyses are performed.
