Infrasense Non-Destructively Evaluates Condition of Bridge in Virginia Beach, Virginia with Infrared Thermography and Ground Penetrating Radar

Infrasense completed a vehicle-based inspection of a bridge deck in Virginia Beach, Virginia. The methods of testing included Ground Penetrating Radar (GPR), Infrared Thermography (IR) and High-Resolution Imaging (HRI). Testing was performed in August and September, with the goal of mapping rebar depth and quantifying areas of concrete deterioration, rebar-level delamination, spalling, and patching. The…

Infrasense Performs Ground Penetrating Radar (GPR) and Infrared Thermography (IR) Condition Surveys of the Granby Street Bridge Deck in Norfolk, Virginia

Infrasense mobilized from Boston to Virginia to survey Norfolk’s 64,000 square foot Granby Street Bridge. The GPR survey was done in March, and the IR survey was done in April, when the weather conditions were sufficient for revealing subsurface delaminations. The GPR survey was performed at normal driving speed, and IR was done at a…

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…
