Road Structure Evaluation and Analysis

Highway professionals require a safe and reliable method to non-destructively evaluate roads for planning and rehabilitation purposes. GPR provides users with an effective tool for quickly determining pavement layer thickness and evaluating base and sub-base layers with data densities not obtainable by other labor-intensive methods such as coring.

GSSI’s RoadScan system uses the only FCC certified air-launched horn antennas in the industry. These unique antennas measure layers as thin as one inch.

RoadScan data is acquired at highway speeds making it possible to collect hundreds of miles of road data in just one day. This eliminates the need for lane closures and provides a safe working environment. With GSSI’s new EZ Tracker layer picking tool, data processing is simple, faster and easier than ever.

Road Evaluation Application Using GPR

RoadScan has been fully integrated with the JILS 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 integrated FWD/GPR combination vehicle.

Road Professionals Use GRP For:

  • QA of new asphalt thickness
  • Measurement of existing asphalt thickness prior to milling operations
  • Integration with FWD – collect & store asphalt thickness at every FWD location.
  • Base and sub-base evaluations
  • Geo-textile performance testing
  • Void detection and location
