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…

Ground Penetrating Radar (GPR) Survey of Pavement Structure Near East Greenwich, Rhode Island

In early April, Infrasense conducted a non-destructive survey and report for 10 lane miles of a section of Route 2, in Rhode Island. The project provided the client with 4 sets of data showing where concrete appears to be present under the asphalt pavement versus an aggregate base. The survey was conducted at driving speed…

Pavement Thickness Survey Along Section of I-85 in South Carolina

In May 2017, Infrasense carried out a GPR pavement thickness survey of 24 lane-miles of I-85 near Spartanburg, SC. The right shoulder, right lane, center lane, and left lane were surveyed in both northbound and southbound directions. The results of the survey included a statistical summary of the pavement layer thicknesses in each lane, as…
