  • Abstract:
    Managing a growing population of deteriorated transportation infrastructure ; systems (i.e. bridges, railways, tunnels) is one of biggest challenges faced by the nation. ; Traditional inspection and monitoring techniques (e.g., visual inspection, mechanical ; sounding, rebound hammer, cover meter, electrical potential measurements, ultrasound, ; ground penetrating radar) for bridges, railways, and tunnels require lane closure and are ; labor intensive and time-consuming. Existing remote sensing techniques (e.g., LiDAR, ; aerial photos) using fixed-wing aircraft are capable of conducting large-area inspection ; but are constrained by viewing areas accessible only from above, at a large distance, and ; are not capable of inspecting all areas of interest (e.g., bridge piers, bridge girder bottom, ; and tunnel walls). Automated, low-cost, efficient inspection techniques for interrogating ; critical components of bridges, railways, and tunnels are needed. The objective of this ; project is to develop a system-level, decision-support unmanned aerial vehicle (UAV) ; sensing system for the autonomous, efficient inspection of bridges, railways, and tunnels, ; using radar, digital image correlation, and thermal sensors. The proposed UAV sensing ; system represents the next generation of rapid, low-cost interrogation technology for ; infrastructure inspection and monitoring of critical transportation infrastructure. ; In this final report, major research achievements and findings from our conducted ; tasks are summarized and reported. Additional technical details in our research tasks can ; be found in submitted quarterly reports. The objective of this project is to develop an ; unmanned aerial vehicle (UAV) system that can be used to autonomously interrogate ; numerous areas on civil structures easily without requiring expensive, time consuming ; aerial lifts or inconsistent visual inspections. The proposed sensing platform includes ; innovative continuous wave imaging radar and digital image correlation to monitor ; structures or quantify damage. This project represents the next generation of localized, ; autonomous inspection and monitoring methods using robotic platform.
