scope:

This document outlines a method to measure the typical external noise emission produced when tyres of passenger car roll over a structured road marking. The result is a measure for the noise perceived in the surroundings of the road, hence not for interior noise in the car.

This method can be used for three purposes:

- determination of initial acoustic properties of a road marking, yielding a noise label for a given system;

- testing of the acoustic conformity of a particular marking to the noise label determined during the determination of initial acoustic properties;

- monitoring of the acoustic properties in the course of its lifetime.

The test result allows the road owner to make an assessment of the risk of nuisance when s/he considers a particular road marking system for application on a road in a noise sensitive area, e.g. built up areas. The method is also applicable to measurements on milled rumble strips.
