This document specifies the essential characteristics of a test track surface intended to be used for measuring rolling sound emission of vehicles and their tyres.
The surface design given in this document
— produces consistent levels of tyre or road sound emission under a wide range of operating conditions including those appropriate to vehicle sound testing,
— minimizes inter-site variation,
— limits absorption of the vehicle sound sources, and
— is consistent with road-building practice.
