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 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…
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…
