The Weighted Longitudinal Profile

ABSTRACT The new method presented in this paper allows the location and individual evaluation of the whole range of phenomena concerned with the longitudinal evenness of road pavements: irregular unevenness, periodicities and transients. It combines the advantages of the response-type methods—implicit valuation of shape and size of unevenness in terms of driving dynamics—with those of purely geometrical methods of evaluation: objectivity and independency of restrictions to certain vibration properties and speeds. The deduction of the method is presented extensively and several example evaluations are given. By comparison to alternative approaches it appears to be a promising evaluation concept.
