Infrasense conducted a nondestructive survey and report on the main travel lanes of a 1-mile section of Rubber Avenue in Naugatuck, CT. The project provided the client with tabular and graphical data sets plotted at a 5-ft interval along the centerline of each travel lane, with each point linked to precise GPS coordinates. These datasets…
This past summer, Infrasense surveyed 10 miles of interstate pavement and 23 bridge decks with ground penetrating radar. The objectives of the GPR survey included: Locating the lateral and longitudinal extents of the underlying PCC pavement and full-depth asphalt pavements Providing thicknesses of asphalt and PCC pavement layers Locating and quantifying deterioration in the underlying…
Infrasense completed a subsurface pavement structure investigation of 18 sections of pavement in Western Maryland using high-speed ground penetrating radar (GPR). The sections were surveyed in both driving directions to obtain continuous structure information for both bound and unbound material layers. The GPR results will be used to supplement Falling Weight Deflectometer (FWD) back-calculations to achieve…
Infrasense recently surveyed multiple runways, a taxiway, and a 240,000 square-foot apron at the San Francisco International Airport. The survey implemented a combination of 400 MHz and 1 GHz antennas mounted off the back of the survey vehicle. The use of both frequencies provided an excellent combination of data resolution and depth of penetration to…
Infrasense completed a non-destructive survey of two intersecting multilane roadways in Virginia Beach, VA. The survey provided the client with subsurface pavement structure data along all driving lanes, shoulder lines, and turn lanes within the project section. Pavement layer thicknesses were plotted to produce a complete profile of the pavement structure. The profiles and layer…
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…
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…
Infrasense developed a roadway structure database to assist the Idaho Transportation Department (ITD) in its future project planning and design efforts and to ultimately advance the condition of the roadway to an acceptable level. The roadway structure database covers approximately 1000 miles of state highways within ITD’s District 6 and was generated primarily with data…
