  • Specifications

The affordable RoadScan™ 30 system provides users with an effective tool for quickly determining pavement layer thickness. RoadScan is able to collect data densities not obtainable using other labor-intensive methods. RoadScan data can be acquired at highway speeds, which eliminates the need for lane closures and provides a safer working environment.

The RoadScan system is available in 1-4 channels for job site flexibility.

Typical Uses for RoadScan Include:

  • Measuring pavement thickness
  • Flexible control structure permits easy integration with data collection vehicles
  • Base and sub-base evaluations
  • Measuring available asphalt prior to milling operations
  • Geo-textile performance testing
  • Railroad substructure assessment

Advantages

  • Data acquired at highway speeds
  • No coring required for calibration
  • Data quality not affected by rough road conditions

Acquire Data

  • Quick determination of pavement layer thickness
  • 1.0 or 2.0 GHz antennas provide superior data resolution
  • Multi-channel data collection allows 1, 2 or 4 antennas to be used simultaneously
  • 2 GHz antenna provides superior data resolution for measuring lifts as thin as one inch

Deliver Results

  • ASCII output files for simple data transfer to other software programs
  • Results output as Google Earth™ .kml file

Value

  • Flexible antenna mounting adapts to most vehicles
  • Flexible system for concrete and bridge inspection applications
  • Two-year warranty
  • FCC certified version available for US customers
