Feasibility of Early Damage Detection Using Surface Mounted Sensors on Existing Pavements

项目名称：	Feasibility of Early Damage Detection Using Surface Mounted Sensors on Existing Pavements
摘要：	Previously developed work by Michigan State University (MSU) led to the development of an innovative sensing system for continuous health monitoring of pavement structures. The developed sensor is capable of detecting damage accumulation in pavement structures under actual traffic and environmental load history. The first sensor package prototypes were built so that they have a similar shape to existing systems (H-shape), and can be installed using existing procedures that were previously used by State Highway Agencies (SHAs). Further enhancements that are currently being investigated include miniaturizing the sensor to a size of the same order of a coarse aggregate particle. While the development of the new sensor constitutes a major achievement towards the future implementation of self-powered autonomous sensor networks for the continuous health monitoring of in-service pavements, there are still a multitude of hurdles to overcome before the acceptance into practice by SHAs. Furthermore, new pavement construction projects are negligible when compared to the extent of the exiting pavement network. It is thus more critical for state highway agencies (SHAs) to adopt monitoring techniques that can be adapted to existing pavements. This research will investigate the feasibility of surface mounting installation procedures on existing pavements without major interference with regular maintenance activities. In addition, this work will examine the formatting and integration of the generated data with the existing pavement management and preservation systems. This integration is critical for a successful adaption of any developed technology.
