Statewide Pavement Structure Evaluations in Virginia

Infrasense has performed a variety of different pavement projects across the state of Virginia, including statewide and citywide network-level evaluations and localized project-level evaluations for rehabilitation design. The largest of these projects was a statewide network-level pavement evaluation to support the Traffic Speed Deflectometer (TSD) structure analysis of 2,520 miles of primary roads throughout Virginia. Infrasense recommended 260 locations for confirmative coring, and a statistical comparison of the GPR and coring results; for the project, GPR asphalt thickness results are within 6% of the measured core thicknesses.

On a smaller scale, Infrasense performed network-level pavement structure evaluations for the entire city of Falls Church, Virginia. We collected 80 lane-miles of GPR and GPS data synchronously at multiple offsets on every public road in the city. The vehicle-based data collection took only 3 days and required no road closure or traffic detours. Results were provided to the client as both tabular and GIS-compatible formats.

At the project-level, Infrasense has performed pavement structure evaluations at a number of different locations in Virginia to aid future maintenance and rehabilitation planning. The length of these pavement sections has ranged from less than a mile to nearly 10 miles. For these types of projects, GPR data is collected at multiple offsets across the lanes and shoulders in order to provide more detailed pavement structure information for each section.

NDE Scanning and Mapping of Hampton Roads Tunnel Conditions

The Virginia Department of Transportation commissioned Infrasense to perform condition evaluations of the walls and roadway deck of the Hampton Roads Tunnels, which carry I-64 below the Chesapeake Bay in Norfolk, Virginia. The eastbound and westbound tunnels are 7,315 feet and 7,470 feet in length, respectively. The tunnel wall evaluations were carried out using a…

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…
