ISO 13473-5:2009规定了通过测量表面轮廓曲线并从该轮廓计算巨纹理描述符来确定路面巨纹理平均深度或水平的程序。该技术旨在为各种用途提供有意义且准确的路面纹理特征测量和描述。 由于巨纹理和周围范围之间存在重叠，因此巨纹理描述符不可避免地与这些范围内的相应度量具有一定的相关性。 ISO 13473-5:2009规定了与ISO 13473-1、ISO 8608和EN 13036-5兼容的相关部分中的测量和程序。

ISO 13473-5:2009 specifies procedures for determining the average depth or level of pavement surface megatexture by measuring the profile curve of a surface and calculating megatexture descriptors from this profile. The technique is designed to give meaningful and accurate measurement and description of pavement megatexture characteristics for various purposes. Since there is an overlap between megatexture and the surrounding ranges, the megatexture descriptors unavoidably have a certain correlation with corresponding measures in those ranges. ISO 13473-5:2009 specifies measurements and procedures which are in relevant parts compatible with those in ISO 13473-1, ISO 8608 and EN 13036-5.
