HZ-4511 Automated pavement longitudinal profile analyzer
    Measured flatness index: the flatness of the international roughness index (IRI) standard deviation (σ) observation score value (RN) plus or minus to the height difference of the cumulative value of the absolute height (height difference) greater than the high points of a given distribution of ride qualityindex (RQI). Output: various flatness index (above) the whole pavement longitudinal profile curve and the sample point height (height difference) data a variety of flatness index distribution map road longitudinal profile slope (slope).

Machine Summary:

Measured flatness index: the flatness of the international roughness index (IRI) standard deviation (σ) 

observation score value (RN) plus or minus to the height difference of the cumulative value of the

absolute height (height difference) greater than the high points of a given distribution of ride qualityindex 

(RQI). Output: various flatness index (above) the whole pavement longitudinal profile curve and the sample

 point height (height difference) data a variety of flatness index distribution map road longitudinal profile 

slope (slope).
