The aim of this paper is to analyse pavement profiles by using a theoretical approach in order to identify a reliable pavement profile data processing procedure for evaluation of pavement macrotexture according to the definition of the ISO 13473-1, and to verify the assumption of equivalence between the profilometric and volumetric methods. The effects of different pavement profile data processing methods were therefore analysed using two types of filters: Butterworth’s numerical filters and moving average filters. By careful analysis of texture levels, this work identifies the procedure that produces the most stable and significant results both from a statistical point of view and in terms of a description of the phenomena involved. Finally, the study also aimed to identify the data processing method that best reproduces the sand patch method for mean texture depth evaluation.

Abstract
The aim of this paper is to analyse pavement profiles by using a theoretical approach in order to identify a reliable pavement profile data processing procedure for evaluation of pavement macrotexture according to the definition of the ISO 13473-1, and to verify the assumption of equivalence between the profilometric and volumetric methods. The effects of different pavement profile data processing methods were therefore analysed using two types of filters: Butterworth’s numerical filters and moving average filters. By careful analysis of texture levels, this work identifies the procedure that produces the most stable and significant results both from a statistical point of view and in terms of a description of the phenomena involved. Finally, the study also aimed to identify the data processing method that best reproduces the sand patch method for mean texture depth evaluation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
