1 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.
