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

Share Article

In the early August, Infrasense conducted a ground penetrating radar survey on two multilane roadways in Virginia Beach, VA. The survey resulted in continuous, high resolution subsurface data including pavement layer thicknesses for all driving and turn lanes along two major local roadways.

The survey results included the layer thickness values in spreadsheet format along with stationing and GPS coordinates. In addition, plots of the pavement structure were provided.

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 thicknesses in tabular format were provided with recommended coring locations for subsequent validation. The GPR survey was conducted at driving speed over the course of an afternoon with no closures, no disruption to traffic, and zero impact to the integrity of the road.

The GPR data collection system included a pair of 1 GHz horn antennas and a SIR-30 control unit, both manufactured by GSSI in the United States. The survey results included the layer thickness values in spreadsheet format along with stationing and GPS coordinates. In addition, plots of the pavement structure were provided.

The GPR pavement surveys are carried out according to ASTM D4748-10. The resulting data shows a cross-sectional slice of the pavement strata at various offsets. Each slice includes the surface, and any material change in the first few feet below the surface.
