Road Engineering - RIS Hi Pave

The 'Faster' and most flexible solution for Road Assessment Survey

 

The IDS RIS Hi Pave system is state of the art technology that provides its users with the ability to conduct detailed pavement inspections. It has the following key cababilities: 

  • Measures pavement thickness
  • Assesses surface, base and sub-base road course
  • Detects cavaties, voids and delamination
  • Locates cracks and pavement integrity
  • Detects wet areas
  • Airport Runway condition assessments

 

 

The RIS HI Pave has one of a kind features including: 

 

  • A survey speed of over 250km/h
  • Investigating pavement, base and sub-base course conditions simultaneously
  • High resolution scans from the new horn antennas (1GHz and 2GHz)
  • Flexible antenna configurations
  • Lightweight and compact design 

It can be configured as either a single double frequency antenna unit or as an array composed of 2 or 3 of these units. The two frequencies used are 600 MHz (for characterising relatively deep layers) and the choice of either 1600 or 2000 MHz (for characterising asphalt or concrete pavements respectively).

The method chosen depends on your requirements in terms of layer detection performance and survey speed. A mechanical support is supplied to enable this special antenna to operate in contact with the ground for high accuracy surveys.

IDS has also developed the specific IDSGRED/IN/LAYERING software for this application.

 

 

 

 

 

 

 

 

Rail Engineering


SafeRailSystem (SRS): an integrated solution allowing the user to autonomously inspect railway ballast for renewal and maintenance.
 

 
SRS is the higher speed radar system for the inspection of Ballast quality specialized for the following application:
 
  • Continuous mapping of ballast thickness;
  • Location of areas with insufficient bearing capacity;
  • Differentiation between clean and fouled ballast;
  • Detection of sections with drainage problems.

System composition:
  • High speed radar control unit;
  • Three or four antenna array;
  • Data Logger and visualisation system;
  • Doppler radar position encoder;
  • Video camera synchronised to radar data;
  • Dedicated post-processing software module for an efficient interpretation of SRS data;
  • Customer training and support program to introduce the user to the autonomous and efficient operation of SRS.

Radar Antennas can be mounted on any kind of rail vehicle and enables the user to detect undertrack problems which can cause track geometry anomalies. It provides complete information about the ballast status.
 
Benefits:
  • Easy interpretation of ballast status trough automatic tools;
  • Improved track maintenance decision making;reduce current costs fro track investigations procedures maintenance and renewal operations;
  • Continuous monitoring increases network management profitability;
  • Improved work specification to less reworking.
     
    The acquisition laptop and control systems are easily installed inside the train cabin. The highly integrated hardware/software setup permits the acquisition process to be performed by a single operator.
     
    System features:
    •  Three or four simultaneous profile covering the whole track;
    • Accurate positioning trough Doppler encoder and GPS positioning;
    • Synchronised video and position assist in quick interpretation of results.

    Post processing software:

    SafeRailSystem includes an unique post processing software - SRS DPA - dedicated to the railway foundation for ballast inspection and analysis. This software includes advanced automatic "pattern recognition" algorithms, which assist the evaluation of ballast status and an automatic function for layers interface detection.
    The operator can visualize, simultaneously, up to 4 parallel radar maps and run these sections with an automatic scrolling. All the radar data can be selected in a rapid and efficient way. The user can introduce and analyze drilling information.
