1 Scope This document describes an assessment procedure for characterizing the effect of different pavement types on road traffic noise emission. The procedure relies on the application of an established measurement method and specifies the detailed conditions for its use to enable the determination of characteristic values for the acoustic performance of road surface types with a given accuracy. Performance is characterized in absolute terms rather than with respect to a reference surface, as specifications for the latter differ from country to country and could contribute to additional uncertainty. The procedure is intended to be suitable for the following applications:

for the acoustic labelling (i.e. the determination of initial acoustic properties) of generic or proprietary road surface products; for the conformity-of-production (COP) assessment of newly laid surfaces, e.g. to assess compliance with acoustic labels and/or contract specifications, or to assess the homogeneity of the surface over its length; for the monitoring of the acoustic properties of road surfaces over the course of their working lifetime, so as to help inform surface maintenance/replacement policies and increase understanding of the acoustic durability of road...
