The ROMDAS Z-250 Reference Profiler measures high accuracy reference profiles of the road surface. 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 surface profiler is highly portable, easy to carry and use. It is an excellent tool for measuring roughness profiles for post-construction compliance or for setting up calibration/validation sites for vehicle mounted roughness profilers.

The Z-250 is ‘walked’ along the road surface recording the elevation at 250 mm intervals along the road. A Bluetooth connection from the Z-250 to an Android mobile device makes it easy for use and shows real-time display of all readings and IRI values.

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

• Calibrating or validating vehicle mounted roughness measurement system e.g. the ROMDAS 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 model or calibrating/testing existing HDM roughness models.

The Z-250 Android software application is now standard with the ROMDAS Z-250 Profiler, which is an excellent option when collecting accurate roughness data for calibration or validation. The Z-250 measuring unit contains a precision inclinometer which outputs to an Android device that immediately records and processes the data.

The software will store the surveys on the device and can be downloaded to a computer system for further analysis with ProVal or similar software. With it’s user-friendly software, the ROMDAS Z-250 road profiler greatly reduces the risk of human error during collection and processing of high accuracy roughness data.
