Road and airfield surface characteristics - Test methods - Part 5: Determination of longitudinal unevenness indices

Scope

This document defines different possible methods for processing digitised road profiles:

- Computation of the International Roughness Index (IRI) ; based on the Golden car characteristics,

- Spectral analyses : Wave band analysis and Spectrum analysis, based on the Power Spectral Density (PSD).
