Infrasense was in western Massachusetts this past week completing a suite of tests along the abutments of a bridge to quantify and map deterioration, as well as identify concrete compressive strength, rebar spacing, and rebar depth.
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.
#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…
Infrasense has developed a collaboration with GPR Imaging Solutions PTY LTD of Melbourne, Australia. GPR Imaging Solutions was formed in 2013 to introduce high speed subsurface scanning into the Australian market. As part of this collaboration, Infrasense has advised GPR Imaging Solutions in implementing the equipment for roadway scanning, and has provided data analysis support…
Infrasense supported the research team at Northeastern University in developing a survey vehicle system to automatically detect and process surface and subsurface roadway defects. The project, entitled VOTERS (Versatile Onboard Traffic Embedded Roaming Sensors), is part of NIST’s Technology Innovation Program, and focuses on the subsurface sensing of pavements and bridge decks. Some of the…
Infrasense contributed to the original research efforts for the SHRP2 project titled, “Advanced Methods to Identify Pavement Delamination (R06D)”. The objective of this project was to identify and validate nondestructive testing technologies that can detect delamination in hot-mix asphalt (HMA), to operate at a reasonable travel speed, and cover a full lane width. Most recently,…
Infrared thermography is one of our primary testing technologies for Wisconsin bridge deck condition evaluations, and we are always seeking ways to improve our testing methods. In 2017, this research really took flight – literally! Infrasense has also been working with a national aerial imaging company to collect and analyze infrared and visual imagery from…
