Z-250 Reference Profiler

The ROMDAS Z-250 Reference Profiler has been developed to measure high accuracy reference profiles. The linear elevation profiles are then analysed using industry standard algorithms to determine the road roughness in terms of IRI (m/km).

This Class 1 profiler can easily be packed into a suitcase and is an excellent tool for measuring roughness profiles during post-construction or for setting up calibration/validation sites for vehicle mounted roughness profilers.

The Z-250 is ‘walked’ along the road recording the elevation (in mm) at 250 mm intervals along the road.

A Bluetooth connection from the Z250 to its hand-held data logger makes for easy use and shows real-time display of all readings and rolling IRI values.

Data is easily transferred to office computers via USB for additional analysis using free industry standard software such as ProVal or RoadRuf if required.

Key Benefits & Features

  • Automatically calculates IRI for calibration/validation sites
  • Outputs in Text and ERD files
  • Data is compatible with other recognised software for analysing road profiles (e.g. ProVal & RoadRuf)
  • Very compact and portable unit
  • Bluetooth compatible
  • Window Mobile operating system compatible
  • Use the plotting function to instantly graph the profile’s change in elevation

What are reference profiles are commonly used for?

  • Calibrating or validating vehicle mounted roughness measurement system (e.g. the ROMDAS® or TRL Bump Integrator);
  • Quality control for construction and infrastructure projects such as highways, car parks, bridges and airports
  • Collecting data for research purposes, such as developing a new roughness deterioration models or calibrating/testing existing HDM roughness model.

Z250 Reference Profiler Software

This software comes standard with the ROMDAS Z250 Profiler, which is an excellent option when collecting accurate roughness data for calibration or validation. The measuring unit contains a precision inclinometer which outputs to a data logger that records and immediately processes the data.

The surveys are stored and can be downloaded to a PC for further analysis using ProVal or RoadRuf software if required.

With its clear and easy-to-use software, the ROMDAS Z250 greatly reduces the risk of human error during collection and processing of high accuracy roughness data.
