标准范围

本文件规定了用于测量车辆及其轮胎滚动声发射的试验跑道表面的基本特性。本文件中给出的表面设计-？在各种操作条件下产生一致的轮胎或道路声发射水平，包括适用于车辆声音测试的条件，-？最大限度地减少站点间的变化，-？限制车辆声源的吸收，以及-？符合道路建设惯例。

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.
