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

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…

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…
