Umfang (scope):
This European Standard specifies the characteristics of aggregates and filler aggregates obtained by processing natural, manufactured or recycled materials and mixtures of these aggregates for use in bituminous mixtures and surface treatments for roads, airfields and other trafficked areas. It covers aggregates having an oven-dried particle density greater than 2,00 Mg/m3. It also covers recycled and manufactured aggregates with particle densities greater than 1,50 Mg/m3 with appropriate caveats (see Annex A). Assessment of the density of recycled aggregates is typically carried out on coarse fractions. NOTE 1 Requirements for lightweight aggregates are specified in prEN 13055. The use of aggregates as soil is not covered by this standard. NOTE 2 due to huge variation of geological and pedological conditions in Europe, precise definition of soil can be found in the documents related to the application at the place of use. This European Standard does not cover the use of reclaimed bituminous mixtures (see NOTE 3). A list of the source materials that have been considered and indicating those which are within the scope of this Standard is given in Annex A (normative). Requirements for the Assessment and Verification of the Constancy of Performance (AVCP) of aggregates to this European Standard are given in FprEN 16236. Aggregates used in construction are meant to comply with all the requirements of the relevant European Standards for aggregates. These standards include comprehensive and specific requirements for natural aggregates, manufactured aggregates and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constitutents of recycled aggregates. NOTE 3 Requirements for reclaimed asphalt for use as a constituent of asphalt mixtures are specified in EN 13108-8 and are therefore not covered in this standard. EN 13108-8 does however call up the general requirements of EN 13043 for the aggregate component of reclaimed asphalt.
