Vehicle-mounted road surface profilometer
This equipment can detect the dynamic mechanical response of the longitudinal roughness change of the road surface to the detected vehicle in real time, and convert the measured dynamic mechanical response into various roughness indexes through mathematical models (international roughness index IRI, roughness standard deviation , bump accumulation value VBI, ride quality index RQI, etc.). It can evaluate the roughness of various roads and airport runways under normal vehicle speed, and can be used for road maintenance management evaluation and roughness index acceptance of road construction. This equipment is easy to install and cost-effective.
