Infrasense leverages advanced Aerial IR and visual imaging to map bridge deck delaminations, patching, and spalling. Using high-sensitivity thermal cameras, we can pinpoint areas of deterioration invisible to the naked eye. Our nondestructive approach allows for rapid, large-scale assessments that prioritize efficiency, safety, and affordability while minimizing traffic exposure or disruptions. If you have upcoming…
Rapid Automated Sounding for Bridge Deck Condition One of the newest nondestructive testing technologies in use at Infrasense is our Rapid Automated Sounding (RAS) system. This system elevates the traditional method of detecting bridge deck delaminations by combining automated chain strikes, microphone arrays, and algorithmic audio analysis – delivering impressive accuracy and efficiency. RAS collects…
Infrasense, through multiple work orders, has conducted infrared thermography (IR, per ASTM D4788-03) and ground penetrating radar (GPR, per ASTM D6087-08) surveys on over 800 decks representing 7.7 million sq. ft. in Wisconsin’s SW, NC, NW, NE, and SE regions. In 2017, Infrasense conducted surveys on over just over 130 decks. All GPR data collection…
Infrasense has conducted Ground Penetrating Radar (GPR) surveys on 103 bridge decks (over 800,000 square feet of bridge deck) in Ohio’s District 1 using a dual 1-GHz horn antenna GPR system. The work has been carried out under 2 contracts, the first completed in 2008 and a second currently ongoing. All surveys have been carried…
Infrasense teamed with RS&H to complete a multi-phase project in the Jacksonville area to evaluate the condition of 14 bridge decks. The first phase of the deck condition evaluations was carried out using infrared thermography (IR), ground penetrating radar (GPR), and high resolution video imaging. A second phase, consisting of impact echo (IE) and hammer…
The State of Nevada commissioned a deck rehabilitation project of the “Downtown Las Vegas Viaduct”, which spans over 1.5 miles of I-515, beginning just east of the I-15 interchange in Las Vegas, Nevada. In order to facilitate planning and subsequent design efforts, a comprehensive nondestructive evaluation of the deck condition was carried out by Stantec…
Infrasense carried out high-speed GPR condition evaluations on 236 decks throughout the state of Montana. Of the 236 decks surveyed, 165 were selected for a Level 2 analysis, which involved detailed mapping of the concrete deterioration. Additionally, rebar depth contour plots were created which facilitate more accurate deck repair volume calculations. Per the request of…
Infrasense recently completed bridge deck condition evaluations of 25 bridge decks on or over Interstates 15, 80, and 84 using high-speed ground penetrating radar (GPR), infrared thermography (IR), and high-resolution video (HRV). Of the 25 decks evaluated in this project, 11 were surveyed using GPR, IR, and HRV; the remaining 14 decks were surveyed using…
