Roughometer-III With GPS

Roughometer is a high speed device used for measuring pavement surface roughness. It is a portable type equipment and consists of a small accelerometer (sensor) device installed at the rear axle of survey vehicle, a distance measuring instrument, interface module and a controller. The pavement roughness measurements using this equipment are required to be done preferably at a speed in between 40 to 60 km/hr, in order to obtain most reliable and accurate data. The output is in the units of International Roughness Index (IRI).
