本文件描述了通过测量表面轮廓并根据该轮廓计算纹理深度来确定路面表面宏观纹理平均深度的试验方法（见第3条）。该技术旨在仅提供路面宏观结构的平均深度值，并被认为对路面微观结构和不平度特征不敏感。本文件的目的是提供一种国际公认的确定路面表面纹理深度的程序，该程序可替代传统使用的体积修补技术（通常使用沙子或玻璃珠），提供可比较的纹理深度值。为此，本文件描述了过滤程序，这些程序旨在提供用体积块法确定的纹理深度的最佳可能表示[13]。使用中的现代轮廓仪几乎完全是非接触式的（例如。g、 激光、光缝或光片，仅举几例），本文件主要针对这种类型。然而，这并不排除其他类型轮廓仪的部分应用。本ISO 13473系列是根据规定车辆噪声测量试验表面时确定的需要编制的（见ISO 10844:2014[6]）。根据本文件进行的宏观纹理深度测量通常不足以规定车辆或交通噪声测量的试验条件，但作为补充，与规定路面的其他方法一起使用的应用有限。本试验方法适用于测定路面的平均轮廓深度（MPD）。该MPD可以转换为一个量，该量根据体积面片法估计宏观纹理深度。适用于路面样品的现场试验和实验室试验。当与其他物理试验结合使用时，从本试验方法中得出的宏观结构深度值适用于路面防滑特性的估算（见e。g、 参考文献[15]），噪声特性估计和铺路材料或路面修整技术适用性评估。该方法以及其他测量（如适用），如孔隙度或微观结构，可用于评估路面质量。本文件适用于路面纹理测量，不适用于其他应用。路面集料颗粒形状、大小和分布是本程序未涉及的表面纹理特征。该方法的目的不是提供路面表面纹理特征的完整评估。尤其是，已知如果将该方法应用于多孔表面或沟槽表面，则在解释结果时存在问题（见附录B）。注:涉及表面轮廓方法的其他国际标准包括参考文献[1]、[2]和[3]。尽管这些标准中没有明确规定，但它们主要用于测量金属表面的表面光洁度（微观纹理），不适用于路面。

This document describes a test method to determine the average depth of pavement surface macrotexture (see Clause 3) by measuring the profile of a surface and calculating the texture depth from this profile. The technique is designed to provide an average depth value of only the pavement macrotexture and is considered insensitive to pavement microtexture and unevenness characteristics.The objective of this document is to make available an internationally accepted procedure for determination of pavement surface texture depth which is an alternative to the traditionally used volumetric patch technique (generally using sand or glass beads), giving comparable texture depth values. To this end, this document describes filtering procedures that are designed to give the best possible representation of texture depths determined with the volumetric patch method[13].Modern profilometers in use are almost entirely of the contactless type (e.g. laser, light slit or light sheet, to mention a few) and this document is primarily intended for this type. However, this does not exclude application of parts of it for other types of profilometers.This ISO 13473 series has been prepared as a result of a need identified when specifying a test surface for vehicle noise measurement (see ISO 10844:2014[6]). Macrotexture depth measurements according to this document are not generally adequate for specifying test conditions of vehicle or traffic noise measurements, but have limited applications as a supplement in conjunction with other ways of specifying a surfacing.This test method is suitable for determining the mean profile depth (MPD) of a pavement surface. This MPD can be transformed to a quantity which estimates the macrotexture depth according to the volumetric patch method. It is applicable to field tests as well as laboratory tests on pavement samples. When used in conjunction with other physical tests, the macrotexture depth values derived from this test method are applicable to estimation of pavement skid resistance characteristics (see e.g. Reference [15]), estimation of noise characteristics and assessment of the suitability of paving materials or pavement finishing techniques.The method, together with other measurements (where applicable), such as porosity or microtexture, can be used to assess the quality of pavements.This document is adapted for pavement texture measurement and is not intended for other applications. Pavement aggregate particle shape, size and distribution are surface texture features not addressed in this procedure. The method is not meant to provide a complete assessment of pavement surface texture characteristics. In particular, it is known that there are problems in interpreting the result if the method is applied to porous surfaces or to grooved surfaces (see Annex B).NOTE Other International Standards dealing with surface profiling methods include, for example, References [1], [2] and [3]. Although it is not clearly stated in these, they are mainly used for measuring surface finish (microtexture) of metal surfaces and are not intended to be applied to pavements.
