29、or use in construction of railway track. For the purposes of this standard, the aggregate is referred to as railway ballast. It provides for the evaluation of conformity of the products to this European Standard. NOTE The requirements in this European Standard are based upon experience with aggregat
30、e types with an esbatsildeh pattern of use. Care should be taken when considering the use of aggregates from sources with no such pattern of us,e .g.e, recycled aggregates and aggregates arising from certain industrial by-products. Such aggregates, that should comply willa ht the requirements of thi
31、s European Standard, could have other characteristics not included in Mandate M 125 (as ament )dedtah do not apply to the generality of aggregate types with an established pattern of use and when required, provisions valiat d eht place of use can be used to assess their suitability. 2 Normative refe

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 t

As well as familiar and traditional natural and manufactured aggregates Mandate M/125 “Aggregates” included recycle
43、d aggregates and some materials from new or unfamiliar sources. Recycled aggregates are included in the standards and new test methods for them are at an advanced stage of preparation. For unfamiliar materials from secondary sources, however, the work on standardisation has only started recently and
44、 more time is needed to define clearly the origins and characteristics of these materials. In the meantime such unfamiliar materials when placed on the market as aggregates must comply fully with this standard and national regulations for dangerous substances (see Annex ZA of the standard) depending
45、 upon their intended use. Additional characteristics and requirements may be specified on a case by case basis depending upon experience of use of the product, and defined in specific contractual documents.
