RoadScan

RoadScan

The RoadScan™ 30 system provides users with an effective tool for quickly determining pavement layers at high speeds. RoadScan is able to collect data densities not obtainable using other labor-intensive methods commonly used for pavement testing.

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™.
