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.

Our Work in Virginia

Comprehensive Evaluation of Bridge Decks in Virginia Beach, VA

Infrasense recently completed ground penetrating radar (GPR), infrared thermography (IR), and high-resolution video (HRV) data collection on a pair of decks in southeastern Virginia. These datasets will be used to quantify and map rebar-level delaminations, corrosion activity, spalling, and patching. Additional testing, including targeted coring, chloride sampling, and half-cell potential (HCP), will be carried out…

Infrasense Non-Destructively Evaluates Condition of Bridge in Virginia Beach, Virginia with Infrared Thermography and Ground Penetrating Radar

Infrasense completed a vehicle-based inspection of a bridge deck in Virginia Beach, Virginia. The methods of testing included Ground Penetrating Radar (GPR), Infrared Thermography (IR) and High-Resolution Imaging (HRI). Testing was performed in August and September, with the goal of mapping rebar depth and quantifying areas of concrete deterioration, rebar-level delamination, spalling, and patching. The…

Infrasense and BDI Perform Ground Penetrating Radar (GPR) and Half Cell Potential (HCP) Surveys on Bridge in Norfolk, Virginia

Infrasense and BDI mobilized to Norfolk, Virginia to complete testing on the 1800-foot long bridge deck. The methods of testing included GPR, HCP, coring, and chloride sampling. Testing was performed in September on 14 select panels of the bridge deck, with the goal of identifying rebar depth and spacing, and areas of probable corrosion. The…

Infrasense Performs Ground Penetrating Radar Survey on Multiple Roadways in Virginia Beach

Infrasense completed a non-destructive survey of two intersecting multilane roadways in Virginia Beach, VA. The survey provided the client with subsurface pavement structure data along all driving lanes, shoulder lines, and turn lanes within the project section. Pavement layer thicknesses were plotted to produce a complete profile of the pavement structure. The profiles and layer…

Infrasense Conducts QA for a Recently Paved Road in Virginia Beach, Virginia Using Ground Penetrating Radar (GPR)

This June, Infrasense conducted a non-destructive survey and report for a 2.3-mile section of a multilane roadway, in Virginia Beach, VA. The project provided the client with data from all 4 driving lanes, both outer shoulder lines, and all turn lanes within the section. Pavement layer thicknesses were plotted along with recommended coring locations where…

Infrasense Performs Ground Penetrating Radar (GPR) and Infrared Thermography (IR) Condition Surveys of the Granby Street Bridge Deck in Norfolk, Virginia

Infrasense mobilized from Boston to Virginia to survey Norfolk’s 64,000 square foot Granby Street Bridge. The GPR survey was done in March, and the IR survey was done in April, when the weather conditions were sufficient for revealing subsurface delaminations. The GPR survey was performed at normal driving speed, and IR was done at 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…
