Development of Advanced technology for maintenance of infrastructures

ARTC is developing inspection and diagnostic technology with high efficiency and high precision to achieve the appropriate maintenance for an aging city infrastructure. Our main research themes are the technical development for the longer life of the structure, such as 1) the construction of data-base to provide the information concerning the inspection and diagnosis of the damaged structure, 2) non-destructive inspection technology adopting an image and signal processing, 3) the development of the monitoring and measurement technique applying the latest MEMS sensor and so on, 4] the development of the repair and reinforcemen reinforcement technique adopting a new weld-bonding technology.
