Penetradar performed nondestructive testing (NDT) in France (the project site) to provide a solution to the problem of buried obstacles existing in the ballast that could hamper the production of ballast renewal machines. Penetradar recommended use of its ground penetrating radar (GPR) system for the survey and identified various antennas that may be suitable for the tests--two air-coupled antennas and a ground-coupled antenna. Additionally, Penetradar’s engineering team devised several specialized methodologies for testing and data analysis. A plan was developed to ascertain the efficacy of the antennas in identifying buried obstacles in ballast by using the various data collection methods. After data collection, analysis, and mapping of the detections, Penetradar provided its recommendations.

One of the main applications of Ground Penetrating Radar is for determining pavement layer thickness. Penetradar Corporation incorporates a multi-frequency antenna array in pavement layer thickness surveys to aid in the analysis by providing detailed GPR data at various depths. The pavement depth profile plot below shows the advantage of the multi-frequency antenna array and its ability to measure thickness of both very thin pavement layers and layers at greater depths. The depth profile plot above shows the same pavement section evaluated by three different antennas in the array. The 2 GHz antenna provides a higher resolution at shallower depths […]

Penetradar recently submitted a SHRP-2 Tunnel Liner Inspection report to the Oregon DOT. The inspection included 3 tunnels, the twin Vista Ridge and Tooth Rock, near Portland. The liners were inspected utilizing GPR, Infrared Thermography and High Resolution Imaging, to produce quantitative information, including deterioration, moisture content and voids. Hammer soundings were performed at a height of six feet along the tunnel liners, GPR correlated 67% or 26/39 of delaminated areas found by the soundings in the Tooth Rock concrete liner. The scenery was amazing also.

Penetradar recently shipped two systems out to our clients in Saudi Arabia and Mexico. The IRIS-L single channel system equipped with a 1ns air-coupled antenna was delivered to our client in Saudi Arabia, with onsite training to be completed in early October by Penetradar staff. An IRIS-3 multi-channel system including the industries only 2ns air-coupled antenna, 1ns air-coupled antenna and a 3/4ns air-coupled antenna was delivered to our client in Mexico City. The combination of these 3 antennas allows the user to accurately map pavement thickness and deterioration, from thin layers (3/4ns) to deeper penetration up to 2 meters (2ns) […]
FEATURED PROJECTS
October 26, 2018
A nondestructive inspection of 52 bridge decks was conducted in central New York State utilizing Ground Penetrating Radar (GPR). The objectives of the GPR inspection were to provide an up‐to‐date assessment of the physical condition of the concrete deck, including the overall quantity of deteriorated concrete within the bridge and on a span by span basis. The GPR bridge deck inspection was performed at highway speeds, without the need for traffic control. The nondestructive inspection was conducted for the New York State Department of Transportation.

A nondestructive inspection of 19 bridge decks on the Interstate 44 corridor between Springfield and Joplin, Missouri was conducted utilizing Ground Penetrating Radar (GPR). The objectives of the GPR inspection were to provide an up‐to‐date assessment of the physical condition of the concrete deck, including the overall quantity of deteriorated concrete within the bridge as well as the depth to the top reinforcement. The GPR bridge deck inspection was performed at highway speeds, without the need for traffic control. In addition to the GPR inspection, soundings were carried out on portions of selected bridge decks for correlation with the GPR results. The nondestructive inspection of the I‐44 bridge decks was conducted for the Missouri Department of Transportation, and Crawford, Murphy & Tilly, Engineers and Consultants.

A section of Interstate 85 pavement, located between Spartansburg and Gaffney, SC was inspected using ground penetrating radar (GPR). The objective of the survey was the measurement of the in-situ asphalt pavement thickness. The inspection consisted of a total of 90.2 lane-miles of I-85 pavement. For this inspection, the Integrated Radar Inspection System (IRIS), a vehicular based GPR Inspection system installed with an array of four one nanosecond (1GHz) air-coupled (non-contacting) antennas, was used for the GPR test. Detailed results included a discussion of GPR results for the north and southbound lanes, excel spreadsheet data and plan-view CAD map-pings in .dxf format detailing the asphalt thickness measurements.
