Bridge Deck Testing in North Brookfield, Massachusetts

Our team recently completed testing on a bridge in North Brookfield, MA to provide as-built information including rebar spacing, rebar diameter, and concrete compressive strength in support of a load rating. In order to collect data on the culvert underside, Infrasense engineers used wetsuits and a small raft to keep themselves and the testing equipment dry…

Infrasense Performs in Depth Nondestructive Evaluation of Pavement and Bridges Along I-95 in Southern Connecticut

This past summer, Infrasense surveyed 10 miles of interstate pavement and 23 bridge decks with ground penetrating radar. The objectives of the GPR survey included: Locating the lateral and longitudinal extents of the underlying PCC pavement and full-depth asphalt pavements Providing thicknesses of asphalt and PCC pavement layers Locating and quantifying deterioration in the underlying…

Infrasense Carries Out Nondestructive Infrared Evaluation of Bridge Deck in Wisconsin

This past summer, Infrasense surveyed a bridge deck in La Crosse, Wisconsin using infrared for deck delamination detection according to ASTM D 4788 – 03. The equipment setup involved a dedicated vehicle mounted with a high resolution, distance triggered FLIR infrared camera synced up with a high-resolution visual spectrum camera. Both devices capture a whole…

Infrasense Evaluates Condition of Stone Arch Bridge in Orange, Connecticut With Ground Penetrating Radar

In July of 2018, Infrasense mobilized a two-man team to perform a ground-coupled GPR survey of the road surface on a stone arch bridge in Orange, CT.  With the help of a traffic control unit and a local police officer, the condition survey was carried out during overnight hours with minimal disruption to traffic.  The…

Infrasense Evaluates the Condition of 5 Missouri Bridge Decks Utilizing Ground Penetrating Radar (GPR) Supplemented with Other Methods

This past summer, Infrasense conducted non-destructive surveys and reported for 5 bridge decks in Missouri. The project provided the client with a comprehensive set of condition results to facilitate a data-driven approach to programming rehab and maintenance efforts. As a supplement to the GPR surveys, chain drag, coring, and infrared thermography were used on select bridge…

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 (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…
