Infrasense would like to congratulate our founder and senior principal Ken Maser on receiving the ASCE’s 2019 Wilbur S. Smith Award in recognition of his outstanding accomplishments in Civil Engineering. Ken is a leader in the field of Nondestructive Evaluation and its application to highway infrastructure. He will be presented with the award at the…
DetailsLast month Infrasense performed a high speed pavement survey on a stretch of Interstate highway outside the transportation hub of Atlanta, Georgia. The purpose of the project was to determine the structure for approximately 17 miles of pavement. Did you know that Georgia contains 15 different Interstate highways? That’s good for tenth most in the…
DetailsThis 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…
DetailsThis 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…
DetailsIn 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…
DetailsThis 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…
DetailsInfrasense 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…
DetailsInfrasense 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…
DetailsInfrasense recently surveyed multiple runways, a taxiway, and a 240,000 square-foot apron at the San Francisco International Airport. The survey implemented a combination of 400 MHz and 1 GHz antennas mounted off the back of the survey vehicle. The use of both frequencies provided an excellent combination of data resolution and depth of penetration to…
DetailsInfrasense 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…
