This European Standard shall be given the status of a national standard,
16、 either by publication of an identical text or by endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at the latest by December 2003. Annexes A, B and C are informative. Annex D is normative. According to the CEN/CENELEC Internal Regulations, the natio
17、nal standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland
18、and the United Kingdom. 1 Scope This European Standard specifies requirements for unbound mixtures used for construction and maintenance of roads, airfields and other trafficked areas. The requirements are defined with appropriate cross-reference to EN 13242. This European Standard applies to unboun
19、d mixtures of natural, artificial and recycled aggregates (see annex A) with a upper sieve size (D) from 8 mm to 80 mm and lower sieve size (d) = 0 at the point of delivery. NOTE 1Mixtures with an upper sieve size (D) greater than 80 mm are not covered by this European Standard but may be specified
20、in the place of use. NOTE 2Water content of the mixture and the density of the installed layer are not specified mixture requirements. Both parameters are related to the control of the construction of the layer, and are outside the scope of this European Standard. 2 Normative references This Europea
21、n Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications a

27、TEOther useful terms and definitions are given in EN 13242. 3.1 unbound mixture granular material, normally of a controlled grading with d = 0, which is generally used in pavement bases and sub- bases NOTEAn unbound mixture does not contain an added binder. 3.2 category level of a property expressed
