Nondestructive Condition Evaluations of 19 Decks in Virginia

Infrasense completed high-speed scanning of 19 bridge decks in 11 different counties throughout Virginia, totaling over 250,000 square feet. The scanning included Ground Penetrating Radar (GPR) evaluations. The deliverables included deterioration and rebar cover quantities and maps of the bridge decks. Per the request of the Virginia Department of Transportation (VDOT), individual deck condition reports…

GPR Evaluation of Pavement Network Located in Falls Church, Virginia

Infrasense completed the subsurface pavement structure evaluation of approximately 79.93 lane-miles of public roadways in Falls Church, Virginia using Ground Penetrating Radar (GPR) testing to determine the thicknesses of the pavement structure layers. It was performed along the centerline of each roadway, centerline of each lane, and at an offset approximately 1 foot from the…

Dr. Ken Maser presented the results of a network-level pavement substructure evaluation completed in Idaho at WCPAM 2017.

Dr. Ken Maser Presented on Network-Level Pavement Structure Evaluation at the World Conference on Pavement and Asset Management (WCPAM)

Infrasense’s Dr. Ken Maser presented the results of a network-level pavement substructure evaluation completed in Idaho. The project focused on a network of 700 miles of roadways covering a wide range of geographic and pavement structure conditions. The roadways were continuously surveyed with a Traffic Speed Deflectometer (TSD) and with Ground Penetrating Radar (GPR). The…

Oregon Bridge Testing Is Underway

In mid-May, Infrasense began phase 1 of deck testing on 52 bridge decks throughout 12 counties in Oregon. We have started with the ground penetrating radar testing, and plan to return in July to perform infrared testing under more optimal weather conditions. Phase 2 will begin in late summer or early fall, after preliminary GPR…

New 3D-GPR System Being Used on 2017 Projects!

Infrasense recently deployed an air-launched 3D-Radar system on projects in Iowa, Florida, and Virginia. The high-resolution system contains 21 antennas spaced 3 inches apart, and is capable of penetrating up to 5 feet below the surface. Infrasense has used this system to evaluate bridge deck, pavement, and tunnel deck conditions.

Infrared Testing: The Complimentary Dual Camera System

How our high resolution video complements the abilities of Infrared. Infrared data is collected using a FLIR thermographic camera, which measures surface temperature and can provide information regarding subsurface damage in bridge decks.¬† The camera is mounted to a vehicle and data can be collected at highway speeds with clear and accurate results.¬† After surveying…
