Description of 21/30424373 DC 2021

This document specifies the characteristics of aggregates for use in the construction of the upper layer (superstructure) of railway track.

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

Aggregates covered in this document are railway ballast (see 3.1.2).

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

Aggregates covered in this document are coarse aggregates (see 3.1.10).

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.

This document does not cover:

  1. natural and manufactured aggregates, having oven-dried particle density less than or equal to 2,00 Mg/m3, as they are already specified in prEN 13055:2021,

  2. recycled aggregates, with particle densities less than 1,50 Mg/m3,

  3. aggregates with a nominal upper size greater than 90 mm,

  4. armourstone, as this is specified in prEN 13383-1:2021,

  5. aggregates for construction works, as these are specified in prEN17555-1:2021,

  6. 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 13108‑8:2016,

  7. use of aggregates as soil,

  8. use of aggregates in earthworks, as these are specified in EN 16907:2018, Parts 1 to 6.
