EN 13043:2002 (E)41 ScopeThis European Standard specifies the properties of aggregates and filler aggregates obtained by processing naturalor manufactured or recycled materials for use in bituminous mixtures and surface treatments for roads, airfields andother trafficked areas. This standard does not cover the use of reclaimed bituminous mixtures.It provides for the evaluation of conformity of the products to this European Standard.NOTE 1The requirements in this European Standard are based upon experience with aggregate types with an establishedpattern of use. Care should be taken when considering the use of aggregates from sources with no such pattern of use, e.g.,recycled aggregates and aggregates arising from certain industrial by-products. Such aggregates, which should comply with allthe requirements of this European Standard, could have other characteristics not included in Mandate M 125 that do not applyto the generality of aggregates types with an established pattern of use and when required, provisions valid at the place of usecan be used to assess their suitability.NOTE 2Properties for lightweight aggregates are specified in prEN 13055-2.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter.
