Hard to believe this photo is nearly 30 years old – at the time, Infrasense Founder, Dr. Ken Maser was working with a company in Denmark to carry out GPR surveys for pavement thickness! For most of his career, Ken has been at the forefront of GPR for highway infrastructure applications.
In early autumn of 2020, Infrasense headed to the Hoosier state to perform multi-phase condition surveys on 71 bridges decks as part of an Indiana DOT study carried out by Purdue University. A suite of nondestructive testing technologies were deployed across four groups of bridge decks that were selected using different sets of objectives. The…
DetailsInfrasense recently evaluated the condition of 41 bridge decks located in northcentral Wisconsin. The deck evaluations utilized vehicle-based infrared thermography, high-resolution video, and ground penetrating radar. All testing was carried out at a rolling speed, which allowed for spot verification via hammer sounding. Following the field surveys, the data was transferred to Infrasense’s headquarters in…
Details#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…
