The affordable RoadScan™ system
provides users with an effective tool for quickly determining
pavement layer thickness and performing base and sub-base evaluations
with data densities not obtainable by other labor-intensive methods.
RoadScan data is acquired at highway speeds, which eliminates
the need for lane closures and provides a safer working environment.
GSSI’s new 2 GHz horn antenna provides superior resolution
allowing measurement of layers as thin as 1 inch. RoadScan
has also been fully integrated with Foundation Mechanic’s
JILS truck-mounted Falling Weight Deflectometer (FWD) systems
to collect and store pavement thickness at each FWD test location.
Please visit www.jilsfwd.com for
more information on the FWD/GPR combination vehicle.
The Road Structure Assessment Module complements GSSI’s
powerful RADAN™ software to provide features including:
- Unique calibration feature – applies calibration
for each individual scan location eliminating the requirement
to enter sporadic core data for calibration
- Automatic layer picking – with powerful and flexible
editing capabilities
- Both graphical and spreadsheet view of layer data
- ACSII output files – for simple integration with spreadsheets,
pavement management databases and other programs
Typical Uses of RoadScan Include:
- Measuring pavement thickness
- Integration with FWD
- Base and sub-base evaluations
- Measuring available asphalt prior to milling operations
- Geo-textile performance testing
- Railroad substructure assessment
RoadScan Benefits:
- Data acquired at highway speeds
- Affordable, easy to use system
- Quick determination of pavement layer thickness
- Multi-channel data collection allows two antennas to be used
simultaneously
- Flexible antenna mounting adapts to most vehicles
- ASCII output files for simple data transfer to other software
programs
- 2 GHz antenna provides superior data resolution for measuring
lifts as thin as one inch
- FCC Certified version available for US customers
This affordable system combines GSSI’s rugged SIR-20
data acquisition system with a
wheel-mounted distance measuring instrument,
an air-launched horn antenna, mounting kit and road assessment
software.
