TY - CONF A1 - Wiggenhauser, Herbert T1 - Non-destructive testing in civil engineering at BAM N2 - Non-Destructive assessment of the National Infrastructure in Germany has been the topic of R&D at BAM since many years. In 1989 BAM has established a R&D group dedicated to the development and application of Non-Destructive Testing in Civil Engineering. Since then, this group has left has participated in numerous research projects and cooperated with many researches and institutes worldwide. A complex system of inspection and maintenance is in place to inspect and maintain roads, bridges, tunnels and other installations. Based on visual inspection structures like bridges are inspected regularly. In case of concerns which cannot be resolved in this process, a procedure “Object Oriented Damage Analysis” has been put into place where additional inspection methods, especially NDT methods, are being utilized. NDT methods to establish material properties such as strength, porosity, moisture, carbonation, etc need more attention to strengthen the links between engineers and inspectors. BAM and TU Berlin have established a joint Junior Professor to address this research area with gravity. Research is currently focused on methods, data, validation, certification and standardization. Industry 4.0 has become a widely discussed topic with unforeseeable impact. Current research topics include - Large Aperture UltraSound (LAUS) to evaluate very thick concrete elements (> 1m) - Embedded ultrasound sensors to monitor changes in concrete - Data fusion algorithms for honeycomb detection, corrosion localization and reinforcement diameter determination - Reverse Time Migration to improve imaging of concrete structures - Laser Induced Breakdown Spectroscopy (LIBS) with new applications, improved sensitivity and resolution, new devices - RFID based humidity and corrosion sensors - Analysis of scattered Radar waves for the classification of concrete - Development of reference specimens for selected NDT tasks The presentation will present examples of current research and ideas for research directions.
