Roughometer III

The Roughometer III is a cost-effective, easy to install, portable device that provides objective and repeatable roughness results on both sealed and unsealed roads.

Roughometer3-1Practical and easy-to-use, the Roughometer III provides a simple technique for road quality assessment and has the advantage of an integrated GPS unit and the ability to collect over 8,000 miles of data.

The Roughometer III is a response-type roughness device, complying to World Bank Class 3 requirements. Unlike other devices in this class, the Roughometer III eliminates the uncertainties associated with the vehicle, such as the vehicle’s suspension or passenger weight, by directly measuring the axle movement with a precision accelerometer. This means the Roughometer III does not need to be calibrated experimentally to produce true International Roughness Index (IRI) results.

Once a survey has been undertaken, the Roughometer III processing software enables the data to be formatted into custom graphs, tables and maps.
