This document specifies the characteristics of aggregates for use in the construction of the upper layer (superstructure) of railway track.<\/p>\n

With regard to the material source and production process, this document covers natural aggregate (see 3.1.3<\/span>), manufactured aggregate (see 3.1.4<\/span>), recycled aggregates (see 3.1.5<\/span>), and mixtures of these materials.<\/p>\n

Aggregates covered in this document are railway ballast (see 3.1.2<\/span>).<\/p>\n

Railway ballast refers to aggregates where 100 % of the surface of the particles can be described as totally crushed (see 3.1.2<\/span>) and that are obtained by processing natural, manufactured materials or recycled crushed unbound aggregates.<\/p>\n

Aggregates covered in this document are coarse aggregates (see 3.1.10<\/span>).<\/p>\n

Railway ballast resulting of previously used railway ballast on site and without putting it on the market (reused railway ballast) is not covered by this document.<\/p>\n

This document does not cover:<\/p>\n

  1. \n

    natural and manufactured aggregates, having oven-dried particle density less than or equal to 2,00 Mg\/m3<\/sup>, as they are already specified in prEN 13055:2021<\/span><\/span>,<\/p>\n<\/li>\n

  2. \n

    recycled aggregates, with particle densities less than 1,50 Mg\/m3<\/sup>,<\/p>\n<\/li>\n

  3. \n

    aggregates with a nominal upper size greater than 90 mm,<\/p>\n<\/li>\n

    aggregates for construction works, as these are specified in prEN17555-1:2021<\/span><\/span>,<\/p>\n<\/li>\n

  6. \n

    use of aggregates contained within reclaimed bituminous mixtures, as the reclaimed asphalt for use as a constituent of bituminous mixtures is already specified in EN 13108\u20118:2016<\/span><\/span>,<\/p>\n<\/li>\n

  7. \n

    use of aggregates as soil,<\/p>\n<\/li>\n
