RIS Hi-Pave



RIS Hi-Pave

  • Pavement status evaluation for new road construction (comparing completed pavement, grade and sub grade against design specifications);
  • Periodical status monitoring of road and runaway conditions for preventive maintenance;
  • High-speed GPR solution and semi-automatic layer detection software tools, minimizing survey and processing time;
  • Flexible solution that can integrate up to 8 GPR antennas;

RIS Hi-Pave, a ground penetrating radar solution designed for high speed Road Assessment Surveys. The system is able to operate with several antennas at the same time providing a complete assessment of road conditions, such as:

  • Pavement thickness measurement;
  • Surface, base and sub-base road course assessment;
  • Detection of cavities, voids and delamination;
  • Location of cracks;
  • Detection of wet areas;
  • Airport runway condition assessment.

  • Horn Antennas: Hi-Pave is equipped with air launched horn antennas that can be used without contact with the surface. As a result the operator is able to achieve high speeds without damaging the antenna.
  • Speed: Hi-Pave is the fastest ground penetrating radar for road evaluation. It can reach up to 260 Km/h with a single antenna configuration and 10 cm data sampling or 130 km/h with a dual antenna configuration and 10 cm data sampling. This is 3 times more than the nearest competitor.
  • Semi-automatic procedure for layer recognition: The post processing software uses a semi-automatic procedure to collect information of road subsurface layers.
  • Modular: Hi-Pave can operate with up to 8 antennas in a chain connection using the same control unit. This can also include lower frequency antennas (typical 600 MHz) for grade and subgrade evaluations.

GRED is an advanced processing software specifically designed for the easy and efficient 3D interpretation of IDS GPR data. It includes special tools which allow an easy and fast interpretation of a road’s structure, such as:

  • automatic or manual layers insertion;
  • core sample insertion for data calibration and thickness confirmation;
  • 2D and 3D tomography for an immediate visualization of buried objects (e.g.: buried pipes and utilities, cavities etc.).

GRED’s windows clearly show radar maps, different road layers, core samples and underground anomalies.

The GRED processing software allows simultaneous viewing of different radar maps and enables the sections to scroll automatically. The software can identify the various layers using both automatic and manual procedures, defining the layer thickness which can be verified and confirmed by inserting core samples.

IDS radar data is compatible with the RoadDoctor software supplied by Roadscanners and with GPRSlice.

The GPR data can be saved together with a GPS file to match a radar scan with absolute coordinates. The GPS positions can be easily loaded onto software such us Google Earth.
