Infrasense has recently added three new engineers to the staff in anticipation of a busy 2022! Parker Aubin (right) brings his 4 years of geotechnical engineering experience and passion for geophysics on board. Aidan Rolli (left) stuck around after his 2021 summer internship and is now full time, already contributing to a wide range of…
Infrasense was recently in Minnesota to carry out a pavement thickness survey using ground penetrating radar. The results will be used to assist with future pavement design projects. While there, one of our engineers captured this photo of our survey vehicle under the Milky Way!
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,…
Infrasense has performed pavement structure evaluations for the Minnesota Department of Transportation (MnDOT). Since 2015, ground penetrating radar (GPR) surveys totaling over 480 lane-miles were performed on roads in both the Metro and Northeast regions. For each project, preliminary GPR results were used to select cores to be used for calibration and confirmation of the…
Infrasense has surveyed 181 decks throughout Minnesota’s Metro district and Districts 1 and 6 using Infrared Thermography (IR) and Ground Penetrating Radar (GPR), accompanied by underside visual inspections. GPR data was carried out at highway speeds with no disruption to traffic, and IR data was collected using a rolling lane closure. All traffic control was…
Infrasense recently performed a ground penetrating radar (GPR) survey of the bridge deck carrying Lafayette Road over the Soo Line and B.N. Railroad in St. Paul, Minnesota. The GPR data collection system included dual 2GHz horn antennas and a SIR-30 control unit manufactured by GSSI of Nashua, NH. This GPR survey was carried out at…
