#TBT In 1996, Infrasense worked with UMass Amherst testing railroad tracks to detect fouling in the ballast and deterioration in the wood ties using ground penetrating radar (GPR). Initial testing was done on a test track at the UMass Amherst lab and then equipment was mounted to a HiRail vehicle for field testing on a stretch…
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…
DetailsIn Spring 2018, Infrasense founder Ken Maser traveled to northern Israel to train a local team on how to collect Ground Penetrating Radar (GPR) data for a network-level pavement survey. For the next seven months, the team collected 7000 km of pavement in 2240 management units. The data was continuously uploaded to Infrasense for quality…
DetailsInfrasense conducted a nondestructive survey and report on the main travel lanes of a 1-mile section of Rubber Avenue in Naugatuck, CT. The project provided the client with tabular and graphical data sets plotted at a 5-ft interval along the centerline of each travel lane, with each point linked to precise GPS coordinates. These datasets…
DetailsInfrasense 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…
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…
