Kansas City, Missouri Bridge Deck Surveys

Infrasense traveled to Kansas City, Missouri last week to collect date on several bridge decks using ground penetrating radar (GPR), infrared thermography (IR) and high resolution video (HRV). The data will be analyzed to produce quantities and maps of concrete delamination, deterioration, and other defects.

Wisconsin Bridge Deck Surveys

Infrasense’s bridge deck survey work is “heating up” in Wisconsin as we are now focusing on this year’s infrared thermography (IR) scanning to map areas of rebar-level delamination. We also collect high-resolution visual (HRV) imaging in order to differential surface from subsurface features/ defects. Here’s our survey vehicle and some sample data showing side-by-side IR…

Infrasense Carries Out Nondestructive Infrared Evaluation of Bridge Deck in Wisconsin

This past summer, Infrasense surveyed a bridge deck in La Crosse, Wisconsin using infrared for deck delamination detection according to ASTM D 4788 – 03. The equipment setup involved a dedicated vehicle mounted with a high resolution, distance triggered FLIR infrared camera synced up with a high-resolution visual spectrum camera. Both devices capture a whole…

Infrasense Pilots Aerial Surveys with Infrared Thermography and High Resolution Visual Methods to Evaluate Bridge Decks

Infrasense recently completed an internal research effort to assess the feasibility and accuracy of aerial imaging for mapping bridge deck conditions. The results of this study provided support for implementation on upcoming projects. The primary advantage of the aerial method is its efficiency. Data can be collected for hundreds of bridge decks in a single…

Aerial Infrared Thermography

PILOT PROJECT: Aerial Infrared Thermography Used to Evaluate Wisconsin Bridge Decks

Infrared thermography is one of our primary testing technologies for Wisconsin bridge deck condition evaluations, and we are always seeking ways to improve our testing methods. In 2017, this research really took flight – literally! Infrasense has also been working with a national aerial imaging company to collect and analyze infrared and visual imagery from…
