Infrasense's Innovative Bridge Survey in Whiteside County
Infrasense, Inc. has made significant strides in bridge inspection technology by conducting a comprehensive evaluation of 17 bridge decks and their respective approach and departure slabs located along a major highway in Whiteside County, Illinois. This innovative project utilized state-of-the-art infrared thermography (IR) and high-resolution video (HRV) technologies, allowing for thorough inspections without impeding traffic flow.
The Methodology Behind the Evaluation
The advanced inspection was carried out using a specially outfitted survey vehicle, employing a FLIR Systems Model 640 x 512-pixel infrared camera alongside a 4k resolution high-definition video camera. These devices were strategically mounted on an elevated platform on the vehicle, offering an unobstructed view as data was collected at normal driving speeds. The setup facilitated a seamless integration with real-time distance measurement through a high precision distance measurement encoder (DMI) connected to the vehicle's wheel, ensuring consistent and accurate location tracking for identified defects.
What sets this methodology apart is its non-intrusive approach. The use of IR technology enabled the detection and mapping of subsurface issues, such as delamination, spalling, and patching. The infrared images were compared against typical surface features—including discoloration, oil stains, and rust deposits—to isolate and analyze deficiencies accurately. Each detected defect could be delineated clearly, providing valuable insights into the structural health of each bridge deck.
Benefits of Infrared Thermography and HRV
The benefits of utilizing infrared thermography and high-resolution video techniques for bridge inspections are substantial compared to traditional methods like chain-drag testing. Firstly, these methods are notably more objective, supported by concrete data, reducing subjective interpretations often associated with manual inspections. Secondly, the efficiency of this advanced technology results in time savings, allowing for extensive evaluations without extensive downtime or traffic disruptions. Lastly, safety is prioritized, as the travelling public remains undisturbed during the evaluation, addressing a critical concern in urban infrastructure management.
Future Implications for Bridge Maintenance
The resulting data not only provided detailed visualizations of affected areas but also served as a foundation for future maintenance and rehabilitation planning efforts. By identifying specific problem areas accurately, Infrasense's findings enable more targeted and effective maintenance strategies, ultimately prolonging the lifespan of bridge infrastructure.
