Infrasense Evaluates the Condition of 5 Missouri Bridge Decks Utilizing Ground Penetrating Radar (GPR) Supplemented with Other Methods

Bridge Deck Scanning, GPR, Missouri, News

This past summer, Infrasense conducted non-destructive surveys and reported for 5 bridge decks in Missouri. The project provided the client with a comprehensive set of condition results to facilitate a data-driven approach to programming rehab and maintenance efforts. As a supplement to the GPR surveys, chain drag, coring, and infrared thermography were used on select bridge…

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

Aerial, Bridge Deck Scanning, High Resolution Visual, Infrared, News

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…

Idaho Bridge Deck Condition Evaluations as Part of Network Level Survey

Bridge Deck Scanning, Idaho

As part of the roadway structure database Infrasense developed to assist the Idaho Transportation Department (ITD), we also collected and analyzed data to assess the condition of each bridge deck located on the pavement network. Infrasense used high-speed Ground Penetrating Radar (GPR), Infrared Thermography (IR), and High-Resolution Video (HRV) testing to create plan view maps…

GPR Condition Surveys of Connecticut Highway Bridge Decks

Bridge Deck Scanning, Connecticut

Infrasense performed high speed scanning on major highway bridges throughout Connecticut, including the Arrigoni Bridge in Middletown, the Sisson Avenue interchange on I-84 in West Hartford, and the complex “Waterbury Stacks” on I-84 in Waterbury. Combined, these projects represent over 1-million square feet of bridge deck. Infrasense collected ground penetrating radar (GPR) data on these…

Condition Evaluation of the Silliman Evans Bridge in Nashville, TN

Bridge Deck Scanning, Tennessee

Infrasense recently completed deterioration mapping for two mainline bridge decks and six adjacent ramp decks, representing over 100,000 square feet. The Silliman Evans Bridges carry Interstate 24 over the Cumberland River, just north of the I-24/I-40 interchange. The deterioration mapping was performed using vehicle-mounted high-speed ground penetrating radar (GPR) to scan each bridge deck without…
