5、reword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a tec

International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters
7、of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 13473-1 w

12、b7 737 IS0 13473-1:1997(E) Introduction Road surface texture determines factors such as noise emission from the tyre/pavement interface, friction between the tyre and road, rolling resistance and tyre wear. Valid methods for measuring surface texture are therefore highly desirable. The so-called ?sa
13、nd patch? method, or the more general ?volumetric patch? method (see clause 3, Definitions) has been used worldwide for many years to give a single and very simple measurement describing surface texture. It relies on a given volume of sand or glass spheres which is spread out on a surface. The mater
14、ial is distributed to form a circular patch, the diameter of which is measured. By dividing the volume of material spread out by the area covered, a value is obtained which represents the average depth of the sand or glass sphere layer, .e. a ?mean texture depth?. The method has been standardized in
15、 IS0 10844 in order to put limits as to surface texture for a reference surface used for vehicle noise testing. The volumetric patch method is very crude; 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
16、network surveys of roads, for example. Along with developments in contactless surface 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 ?predicte
17、d mean texture depths?, many of them quite successfully. The values they give are not always comparable, although individually they generally offer good correlation coeff icients with texture depth measured with the volumetric patch method. It is therefore important to have a standardized method for
18、 measuring the texture depth by a more modern, safe and economical technique than the traditional volumetric patch method, resulting in values which are directly compatible both with the patch-measured values and between different equipment. iii Copyright International Organization for Standardizati

20、aracterization 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 a
21、nd 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 pari of IS0 13473 is to make available an int
22、ernationally 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 spheres), giving comparable texture values. This IS0 13473 series has been prepared as a result of a need id
23、entified when 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 supplemen
24、t in conjunction 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 i s appl
