    Typical Uses
    The RoadScan 30 is typically used to:
    • NDT road evaluation
    • Measure pavement thickness
    • Evaluate base and sub-base conditions
    • Measure asphalt prior to milling operations
    • Determine areas to core
    System Includes
    • SIR 30 Control Unit

    Quick and effective road analysis surveys
    Determine pavement layer thickness and evaluate base and sub-base layers with limited, to no need, of coring required.
    • GSSI RoadScan System

      Non-destructive Pavement Testing

      The RoadScan can quickly collect pavement layer thickness data. The system acquires data at highway speeds, which eliminates the need for lane closures and provides a safer working environment.

    • Deliver Pavement Evaluation Results

      Data can be easily exported as ASCII output files for simple data transfer to other software programs. Or migrate data results as Google Earth™. kml file for enhanced visualization.

    Data Examples
    RoadScan - Data Example 1
    Pavement Layer Data

    Data illustrates the base layer (green) with original pavement (red) and pavement overlay (blue). This data was collected using the RoadScan 30 with the 1 GHz Horn antenna.

    RoadScan - Data Example 2
    Pavement Layer Data

    Dual-channel data represents pavement layer data (top profile) collected with a 2 GHz Horn antenna, and base/ sub-base layer data collected with 400 MHz antenna (bottom profile).

    RoadScan - Data Example 4
    Pavement Layer Data Exported to Google Earth™

    Deliver results with ASCII output files for simple data transfer to other software programs. This data example represents RoadScan 30 data results that has been integrated with Google Earth™.
