DIN EN ISO 13473-5:2010-04 EN ISO 13473-5:2009 (E) 3 Introduction Pavement surface texture largely influences factors such as noise emission caused by tyre/road in
29、teraction (Reference 7), tyre/pavement friction (Reference 8), and comfort, as well as rolling resistance and wear of tyres. Reliable methods of texture measurement are therefore essential. Texture is subdivided into micro-, macro- and megatexture according to ISO 13473-2. A method for measurement a
30、nd calculation of a macrotexture indicator based on a profile measurement is specified in ISO 13473-1. A procedure for measuring macrotexture by the volumetric patch method is described in ISO 10844:19942, Annex A. Currently, no reliable and practical method of measuring pavement microtexture in sit
31、u is available. This part of ISO 13473 aims to provide means of measuring and calculating megatexture indicators useful for pavement surface characterization. Megatexture is an important texture range lying between macrotexture and unevenness. This type of texture has wavelengths of the same order o
32、f magnitude as a tyre/road interface and is often a result of potholes or washboarding. Some common types of singularities, such as a single depressed or protruding spot on the pavement, will also show up in a texture profile spectrum as megatexture. Although some pavements, such as paving stones, p
33、ossess an intrinsic megatexture, it is usually an unwanted characteristic resulting from defects in the surface. The scope of ISO 13473 (all parts) does not include profile analysis of road unevenness, which is dealt with in ISO 86081. DIN EN ISO 13473-5:2010-04 EN ISO 13473-5:2009 (E) 4 1 Scope Thi
34、s part of ISO 13473 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 measurements and descri
35、ptions 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. This part of ISO 13473 specifies measurements
36、 and procedures which are in relevant parts compatible with those in ISO 13473-1, ISO 86081and EN 13036-56. 2 Normative references The following referenced documents are indispensable for the application of this document.

ISO 13473-2:2002 3.1.2 surface profile texture profile
41、 two-dimensional sample of the pavement surface generated if a sensor, such as the tip of a needle or a laser spot, continuously touches or shines on the pavement surface while it is moved along a line on the surface NOTE 1 The profile of the surface is described by two coordinates: one in the surfa
42、ce plane, called “distance” (the abscissa), and the other in a direction normal to the surface plane, called “vertical displacement” (the ordinate). An example is illustrated in Figure 1. The distance may be in the longitudinal or lateral (transverse) directions in relation to the travel direction o
43、n a pavement, or any direction between these. NOTE 2 Adapted from ISO 13473-2:2002. NOTE 3 Texture profile is similar to surface profile but limited to the texture range. NOTE 4 “Texture wavelength” is a descriptor of the wavelength components of the profile and is related to the concept of the Four
44、ier transform of a time series. However, mathematically the correspondence is not exact. Note that vertical displacement (height) has an arbitrary reference.

47、0,5 mm, corresponding to texture wavelengths up to 0,5 mm expressed as one-third-octave centre wavelengths NOTE 1 Peak-to-peak amplitudes normally vary in the range 0,001 mm to 0,5 mm. This type of texture is the texture which makes the surface feel more or less harsh but which is usually too small
48、to be observed by the eye. It is produced by the surface properties (sharpness and harshness) of the individual chippings or other particles of the surface which come in direct contact with the tyres. NOTE 2 Figure 2 illustrates the different texture ranges, with approximate limits regarding their e
49、ffects on vehicle-pavement interactions.
