GSSI introduces the RoadScan 30

February 11, 2016  By  Andrew Macklin

February 11, 2016 – GSSI announced the release of RoadScan 30, a non-destructive GPR system designed for road inspection and analysis.

RoadScan is for measuring pavement thickness, conducting base and sub-base evaluations, and measuring available asphalt prior to milling operations. Transportation professionals can collect hundreds of miles of pavement layer thickness data in a single day.

RoadScan 30 can collect data densities not obtainable using coring or other labor-intensive methods. Data can be acquired at highway speeds, eliminating the need for lane closures and providing a safer working environment by keeping crews out of traffic. The system’s road antennas are air-launched at a height of 18 inches (46 cm), so data quality is not affected by rough road conditions.

The RoadScan system includes a SIR 30 control unit paired with a 1.0 or 2.0 GHz horn antenna that provides strong data resolution. Additional components include a Smart ID module, a wheel-mounted distance measuring instrument (DMI), 7-meter control cable, transit case for the control unit, mounting kit, and an AC adapter.


The SIR 30 control unit is a configurable multi-channel system, allowing users to operate from one to four antennas simultaneously at high speeds. The system can be highly customized to specific needs, using a choice of accessory antennas. Flexible antenna mounting adapts to most vehicles.

The RoadScan system delivers results quickly and efficiently, using ASCII output files for simple data transfer to other software programs. Results can also be output as Google Earth files. The system also features excellent integration with falling weight deflectometers (FWDs) and other devices used to evaluate pavement structural capacity.
