Infrasense recently completed a project where we used GPR to assess settlement issues along a roadway in eastern Georgia. The areas showing evidence of settlement were in the vicinity of an underlying culvert. The GPR survey resulted in maps of subsurface voids and areas with evidence of moisture ingress possibly contributing to the settlement issue.…
Infrasense engineers recently completed GPR scanning of mechanically stabilized earth (MSE) wall systems in the Midwest. GPR data is collected along the fascia walls to measure the air void gap between the back of the fascia walls and surface of the MSE walls. Drilling is also carried out at select locations for direct measurements of…
Infrasense recently completed subsurface scanning of an 1800s cemetery located in central Massachusetts. We used an array GPR system to identify the locations of graves (known and unknown). The multichannel Raptor system allowed for efficient data collection while producing a high-resolution 3D dataset of the subsurface! If you have an upcoming project where we can…
Infrasense is happy to announce that recently, we were able to travel back to Toronto to complete numerous ground penetrating radar (GPR) pavement thickness surveys. This included surveying over 2,600 kilometers of the City’s network! We are grateful to have worked as a subcontractor to ICC-IMS on this project. If you have an upcoming project…
The National Road Research Alliance (NRRA) has selected Infrasense for an exciting research project! This project objective comprises of automating 3DGPR data analysis for concrete pavement evaluations. The research includes developing machine learning algorithms to detect missing, misplaced, or misaligned dowel and tie bars, voids under joints, and other deficiencies in concrete pavements. If you’d…
Infrasense was in Georgia completing ground penetrating radar (GPR) pavement thickness surveys on various project sections. With our vehicle-based systems we were able to collect data at the posted speed limit to detect pavement layer thicknesses, stripping in asphalt pavements, subsurface voiding, and other conditions. If you have an upcoming project where we can be…
Earlier this year, Infrasense engineers travelled to the Hawaiian Islands for GPR data collection. Over 2,400 lane-miles of roadways on the islands of O’ahu, Hawai’i, Maui, Kaua’i, Lana’i, and Moloka’i underwent evaluation. Analysis of the GPR data showed pavement layer thicknesses and other underlying conditions. If you have an upcoming project where we can be…
We provided pavement layer thickness information to facilitate FWD back-calculation efforts, and ultimately the determination of Pavement Classification Numbers (PCNs) for all airport pavement facilities.
Infrasense worked with the Upper Great Plains Transportation Institute and Dynatest Consulting to complete a NDT subsurface pavement structure investigation as part of a legislature-commissioned study to determine the investment needs for all county and township roads and bridges in North Dakota. The pavement investigation project included GPR pavement thickness and structure data collection and…
