Description:

Degradation of bridge components is an ongoing challenge facing the South Carolina Department of Transportation (SCDOT). This report addresses current and evolving technologies to assist with condition assessment of bridges and culverts while increasing worker safety. Technologies investigated include aerial drones, robotic crawlers, and jetyaks. In addition to demonstration and field evaluation of these technologies, live load testing of two bridges was carried out. This approach provided insight into joint efficiency. Acoustic emission data was investigated and found to be a potentially promising technique for shear regions and for long term assessment under ambient loading conditions. Benefit cost analysis indicated that the widespread adoption of aerial drones could significantly benefit the SCDOT for bridge inspections, particularly if SCDOT personnel were trained to operate the devices. It is recommended that aerial drones be implemented immediately and utilized in parallel with visual and tactile inspection of bridges.
