Pavement Thickness Survey Along Section of I-85 in South Carolina

In May 2017, Infrasense carried out a GPR pavement thickness survey of 24 lane-miles of I-85 near Spartanburg, SC. The right shoulder, right lane, center lane, and left lane were surveyed in both northbound and southbound directions. The results of the survey included a statistical summary of the pavement layer thicknesses in each lane, as…


Infrasense Carries out Ground Penetrating Radar (GPR) and Infrared Thermography (IR) Condition Surveys of 17 Bridge Decks in Wisconsin’s North Central Region

This past summer, Infrasense conducted a multi-faceted non-destructive survey and report for 17 bridge decks in Wisconsin DOT’s North Central Region. The project provided the client with a comprehensive set of condition results to facilitate a data-driven approach to programming their bridge inventory. Surveys were performed at normal driving speed with no disruption to traffic.…

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 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…


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.
