This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorse

18、ment, at the latest by February 2009, and conflicting national standards shall be withdrawn at the latest by May 2010. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifyin

19、g any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integ

20、ral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary

BS EN 15381:2008EN 15381:2008 (E) 5 Introduction This standard allows manufacturers to describe geotextiles and geot

22、extile-related products on the basis of declared values for characteristics relevant to the intended use and if tested to the specified method. It also includes procedures for evaluation of conformity and factory production control. This standard may also be used by designers, end-users and other in

23、terested parties and enables them to define which functions and conditions of use are relevant. Performance and index tests for several characteristics are still under study and will be included when the standard is revised. The term “product” which is used in this standard refers to geotextiles and

24、 geotextile-related products. This European Standard is part of a series of standards, addressing the requirements for geotextiles and geotextile-related products when used in a specific application. BS EN 15381:2008EN 15381:2008 (E) 6 1 Scope This European Standard specifies the relevant characteri

25、stics of metallic and non-metallic geotextiles and geotextile-related products used in the construction of pavements and asphalt overlays and the appropriate test methods to determine these characteristics. The intended use of these geotextiles and geotextile-related products is to fulfil one or mor

26、e of the following functions: reinforcement, stress relief and barrier. The use of geotextiles and geotextile-related products is to be considered as a part of an interlayer and asphalt overlay system. This standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318. This standar

27、d provides for evaluation of conformity of the product to this European Standard and for factory production control procedures. This standard defines requirements to be met by manufacturers and distributors with regard to the presentation of product properties. NOTE 1 Particular application cases or

28、 national specifications may contain additional requirements regarding product application or installation and specifying preferably standardized test methods, if they are technically relevant and not conflicting with European Standards. 2 Normative references The following referenced documents are

44、avements subjected to thermal, fatigue and reflective cracking is to reduce the amount of cracking in a new pavement or asphalt overlay. In addition, a barrier to top-down water ingress to the subbase and/or subgrade may be provided for. This is achieved by reinforcement, stress relief, (interlayer)

45、 barrier or a combination of these functions. The producer of the geotextiles and geotextile-related products shall provide the data based on the results of tests specified in this standard.
