IRI Road Surface Roughness Testing Equipment Continuous Eight-wheel Evenness Meter

The eight-wheel evenness meter is used to measure the standard deviation σ of the unevenness of the road surface. It represents the mm meter of the road surface flatness meter and calculates the interval length of 100m for easy printing of results (if it is less than 100m, press the stop button to print the results).

It is used to measure the smoothness of road surfaces, evaluate the construction and usage quality of road surfaces, but not suitable for measuring on roads with many potholes and severe damage.
