17、of surface profiles - Part 1: Determination of Mean Profile Depth Caract it is operator-dependent and can be used only on surfaces which are partly or fully closed to traffic. Therefore, it is not practical for use in network sun/eys of roads, for example. Along with developments in contactless surf

18、ace profiling techniques, it has become possible to replace the volumetric patch measurements with those derived from profile recordings However, several very different techniques have been used to calculate predicted mean texture depths, many of them quite successfully. The values they give are not

19、 always comparable, although individually they generally offer good correlation coefficients with texture depth measured with the volumetric patch method. It is therefore important to have a standardized method for measuring the texture depth by a more modern, safe and economical technique than the

20、traditional volumetric patch method, resulting in values which are directly compatible both with the patch-measured values and between different equipment. . . .

21、 of pavement texture by use of surface profiles - Part 1: Determination of Mean Profile Depth 1 Scope This part of IS0 13473 describes a test method to determine the average depth of pavement surface macrotexture (see clause 3, Definitions) by measuring the profile curve of a surface and calculating

22、 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 part of IS0 13473 is to make available an internationally a

23、ccepted procedure for determination of pavement surface texture depth which is an alternative to the traditionally used volumetric patch technique (generally using sand or glass spheres), giving comparable texture values. This IS0 13473 series has been prepared as a result of a need identified when

24、specifying a test surface for vehicle noise measurement (IS0 10844). Macrotexture depth measurements according to this International Standard are not generally adequate for specifying test conditions of vehicle or traffic noise measurements, but have limited applications as a supplement in conjuncti

25、on with other ways of specifying a surfacing. This test method is suitable for determining the Mean Profile Depth of a pavement surface. This Mean Profile Depth can be transformed to a quantity which estimates the macrotexture depth according to the volumetric patch method. It is applicable to field

26、 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 I), estimation of noise chacteristics (

27、see e.g. IS0 10844), 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. Pavement aggregate particle shape, size, and d

28、istribution 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, care should be exercised in interpreting the result if the method is applied to porous surfaces or to grooved

29、 surfaces (see annex B). NOTE 1 - Other International Standards dealing with surface profiling methods include for example IS0 468, IS0 1878, IS0 1879, IS0 1880, IS0 3274, IS0 4287 and IS0 4288 (see annex F). Although it is not clearly stated in these, they are mainly used for measuring surface fini

30、sh (microtexture) of metal surfaces and do not apply to pavements. This part of IS0 13473 is adapted for pavement texture measurement and is not intended for other applications. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisi

33、473, the following definitions apply. 31 pavement texture: The deviation iavelength ranges defined in 3.4. of a pavement surface from a true planar surface, within the 32 profile: A two-dimensional representation of a surface. The profile of a surface is generated if a sensor, like a tip of a needle

34、 or a laser spot, continuously touches or shines on the pavement surface while it is moved along the surface. See figure A.1 in annex A. The profile of a surface is described by two coordinates: one along the surface plane, called disfance, and the other in a direction normal to the surface plane, c

35、alled amplitude. See figure A.1. The distance may be in a longitudinal or lateral (transverse) direction in relation to the travel direction on a pavement, or any direction between these. In a Fourier analysis, the profile curve can be mathematically described by a series of Fourier coefficients com

36、bined with sinusoidal curves with certain frequencies and wavelengths. 33 texture wavelength: The (minimum) distance between periodically repeated parts of the curve. For normal surface profiles, a profile analysed by its Fourier components contains a continuous distribution of wavelengths. In this

37、part of IS0 13473, the term texWe wavelength (unit: m or mm) is used to describe the wavelengths of a profile taken from a pavement (see figure A.1 in annex A). NOTE 2 - The term wavelength has historically been used mostly in acoustics (with regard to sound waves) or in electrotechnics (with regard

38、 to electrical signals or electro-magnetic waves). Since people may not be accustomed to using the term wavelength in pavement applications, and also since electrical signals often are used in the analyses of road surface profiles, the term texture wavelength is introduced here. The inverse of textu

39、re wavelength is called spatial frequency (unit: m” or cycles/m), which is when multiplied by the factor 27c, called texture angular wavenumber (unit: rad/m). 34 . Ranges of texture 3.4.1 macrotexture: The deviation of a pavement surface from a true planar surface with the characteristic dimensions

40、along the surface of 05 mm to 50 mm (corresponding to texture wavelengths with third-octave bands including the range 05 mm to 50 mm of centre wavelengths). See figure A.2 in annex A for an illustration of the different texture ranges. NOTE 3 - Peak-to-peak amplitudes may normally vary in the range

41、0,l mm to 20 mm. This type of texture is the texture which has wavelengths in the same order of size as tyre tread elements in the tyre/road interface. Surfaces are normally designed with a certain macrotexture in order to obtain a suitable water drainage in the tyre/road interface. The macrotexture

42、 is obtained by suitable proportioning of the aggregate and mortar of the surface or by certain surface finishing techniques. 3.4.2 microtexture: The deviation of a pavement surface from a true planar surface with the characteristic dimensions along the surface of less than 0,5 mm (corresponding to

43、texture wavelengths with third-octave bands with up to 0,4 mm of centre wavelengths). NOTE 4 - Peak-to-peak amplitudes normally vary in the range 0,001 mm to 05 mm. This type of texture is the texture which makes the surface feel more or less harsh but which is usually too small to be observed by th

44、e eye. It is obtained by the surface properties (sharpness and harshness) of the individual chippings or other particles of the surfacing which come in direct contact with the tyres. 3.4.3 megatexture: The deviation of a pavement surface from a true planar surface with the characteristic dimensions

45、along the surface of 50 mm to 500 mm (corresponding to texture wavelengths with third-octave bands including the range 63 mm to 500 mm of centre wavelengths). NOTE 5 - Peak-to-peak amplitudes normally vary in the range 0,l mm to 50 mm. This type of texture is the texture which has wavelengths in the

46、 same order of size as a tyre/road interface and is often created by potholes or waviness. It is usually an unwanted characteristic resulting from defects in the surface. Pavement characteristics at longer wavelengths than 0,5 m are considered to be above that of texture and are referred to as unevenness. 2 ENISO134731:2004
