Pavement Maintenance Management Tools

Pavement management systems (PMMS) are the subject of this article. The author discusses how such systems offer a systematic and consistent method for selecting maintenance and rehabilitation (M&R) techniques. Among these techniques is the prediction of pavement deterioration patterns in order to economically prioritize repair time and costs. The discussion notes pavement evaluation as key to the PMMS process because of the information it offers to planners regarding current pavement conditions. The author emphasizes the importance of pavement prediction models in gathering today's pavement condition data (e.g., riding comfort, load-carrying capacity, safety, aesthetics) to determine tomorrow's pavement condition. Pavement condition measurement is one of the prediction model elements discussed (including distress, deflection, roughness, and skid). Other prediction model elements include a pavement condition survey and rating procedure that uses the industry standard pavement condition index (PCI) to assess current pavement conditions; roughness measurement (to evaluate pavement comfort and safety); skid measurement (to analyze the skid resistance of a pavement); non-destructive deflection testing (using structural pavement assessment techniques to determine true load-carrying capacity). The author concludes that the use of a PMMS leads to a sound understanding of pavement behavior, along with the development of tools designed to assist airport operators in making pavement performance a practical and manageable parameter.
