Multi-Phase Condition Evaluation of a 1.5-Mile Viaduct on I-515 in Las Vegas

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…

GPR Evaluation of 236 Bridge Decks Throughout Montana

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…

Utah bridge deck scanning by infrasense

Nondestructive Condition Surveys of 26 Bridge Decks for Utah DOT

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…

Evaluation of Pascack Road Bridge Deck in NY using Ground Penetrating Radar (GPR)

In order to facilitate rehabilitation planning of an asphalt overlaid bridge deck carrying I-87 over Pascack Road, ground penetrating radar (GPR) was used to quantify and map concrete deterioration. The GPR data was carried out at driving speeds using a vehicle-based system, so no lane closures were required. In addition to being deployed at driving…

Nondestructive Condition Evaluations of 19 Decks in Virginia
