Infrasense's Aerial Infrared Thermography Evaluates 227 Bridge Decks Across Indiana

Assessing Bridge Conditions: Aerial Infrared Innovations by Infrasense



In a groundbreaking initiative, Infrasense, a leader in structural evaluation technology, has conducted comprehensive assessments of 227 bridge decks throughout various major roads in Indiana. By employing advanced aerial infrared thermography (IR) techniques, they have captured critical data essential for understanding the integrity of these vital structures.

The evaluations were conducted using a fixed-wing aircraft flown by a licensed pilot, ensuring compliance with all FAA regulations. As the plane flew over each bridge, it collected a series of infrared and high-resolution visual images. This process is not just effective; it provides a wealth of information vital for maintaining and ensuring the safety of infrastructure.

State-of-the-Art Technology in Use


Infrasense’s approach combines traditional engineering practices with modern imaging technologies. For each bridge surveyed, infrared images were captured and analyzed. Shorter bridges typically required just one image to cover the entire structure, serving as the main analysis basis. Longer bridges, however, necessitated stitching together multiple images to generate a detailed, composite plan-view image.

To enhance the quality of the infrared data, Infrasense utilized proprietary software that processes the infrared images, significantly improving their analysis capabilities. For instance, contrast enhancements help in clearly identifying delaminations—situations where materials are no longer properly bonded. Additionally, thermal banding effects caused by structural elements or surface conditions are minimized, allowing for a more precise interpretation of localized thermal anomalies, which are crucial for identifying underlying issues in bridge decks.

Results That Matter


The analyses yielded quantitative results, identifying key issues such as overlay debonding, spalling, and rebar-level delaminations. With both visual and infrared maps produced, stakeholders now have access to comprehensive summaries detailing the condition of each bridge.

This data is vital not only in immediate safety assessments but also in long-term maintenance planning. Insights derived from such evaluations can inform remedial strategies and allocation of resources, ensuring that necessary repairs and upgrades are prioritized effectively.

A Future of Infrastructure Reliability


As the demand for reliable and safe infrastructure continues to rise, innovations like aerial infrared thermography become pivotal. Infrasense's methods signify a shift toward more efficient, thorough, and less intrusive means of assessing structural health. By integrating aerial survey techniques into engineering assessments, the organization showcases the potential for enhanced infrastructure management across the nation.

In conclusion, the success of this initiative in Indiana underscores the importance of utilizing cutting-edge technology in structural evaluations. The results not only enhance current infrastructure safety but also set a precedent for future projects across the country, marking a significant advancement in how we monitor and maintain vital public assets.
