Infrasense Conducts QA for a Recently Paved Road in Virginia Beach, Virginia Using Ground Penetrating Radar (GPR)

This June, Infrasense conducted a non-destructive survey and report for a 2.3-mile section of a multilane roadway, in Virginia Beach, VA. The project provided the client with data from all 4 driving lanes, both outer shoulder lines, and all turn lanes within the section. Pavement layer thicknesses were plotted along with recommended coring locations where…

Infrasense Performs Ground Penetrating Radar (GPR) and Infrared Thermography (IR) Condition Surveys of the Granby Street Bridge Deck in Norfolk, Virginia

Infrasense mobilized from Boston to Virginia to survey Norfolk’s 64,000 square foot Granby Street Bridge. The GPR survey was done in March, and the IR survey was done in April, when the weather conditions were sufficient for revealing subsurface delaminations. The GPR survey was performed at normal driving speed, and IR was done at a…

Infrasense Pilots Aerial Surveys with Infrared Thermography and High Resolution Visual Methods to Evaluate Bridge Decks

Infrasense recently completed an internal research effort to assess the feasibility and accuracy of aerial imaging for mapping bridge deck conditions. The results of this study provided support for implementation on upcoming projects. The primary advantage of the aerial method is its efficiency. Data can be collected for hundreds of bridge decks in a single…

Infrasense Performs Subsurface 3D-Radar Survey of Brooklyn Terminal

Infrasense recently completed a project using a ground coupled vehicle mounted 3D Ground Penetrating Radar (GPR) system (manufactured by 3D-Radar) to identify subsurface objects that would impede future installation of sheet pile walls at the Brooklyn Terminal. Using the trailer-mounted 3D-Radar step frequency array system reduced the data collection time significantly and provided an excellent…

Idaho Bridge Deck Condition Evaluations as Part of Network Level Survey

As part of the roadway structure database Infrasense developed to assist the Idaho Transportation Department (ITD), we also collected and analyzed data to assess the condition of each bridge deck located on the pavement network. Infrasense used high-speed Ground Penetrating Radar (GPR), Infrared Thermography (IR), and High-Resolution Video (HRV) testing to create plan view maps…

Consulting & Analysis for GPR Imaging Solutions in Australia

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 at Northeastern Universiry

NIST-Sponsored research project to develop vehicle based system system for automatically detecting pavement conditions

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…
