This standard 21/30422932 DC BS EN 17555-1. Aggregates for construction works is classified in these ICS categories:
  • 91.100.15 Mineral materials and products

This document specifies the characteristics of aggregates, i.e. aggregates without added fillers (see 3.1.1 a) and added fillers (see 3.1.1 b), for uses, either with or without high safety requirements, for:

  1. concrete for buildings, roads and other civil engineering works,

  2. bituminous mixtures and surface treatments for roads, airfields and other trafficked areas,

  3. mortars, renders and screeds, e.g. masonry mortar, floor/screed mortar, surfacing of internal walls (plastering mortar), rendering of external walls, special bedding materials, repair mortar and grouts for buildings, roads and civil engineering works;

  4. unbound and hydraulically bound materials for civil engineering works and road constructions.

With regard to the material source and production process, this document covers natural aggregate (see 3.1.2), manufactured aggregate (see 3.1.3), recycled aggregates (see 3.1.4), and mixtures of these materials.

Aggregates covered in this document are:

  1. aggregates without added fillers, including coarse aggregates (see 3.1.8), grit (see 3.1.11), fine aggregates (see 3.1.12), all-in aggregates (see 3.1.13), natural graded aggregates (see 3.1.14); and

  2. added fillers (see 3.1.15).

Coarse aggregates covered in this document are single sized coarse aggregates (see 3.1.9) and graded coarse aggregates (see 3.1.10).

Added fillers covered in this document are natural fillers (see 3.1.16), manufactured fillers (see 3.1.18), mixed fillers (see 3.1.19), composite fillers (see 3.1.20) and recycled fillers (see 3.1.21). Natural fillers include fillers of limestone origin (see 3.1.17).

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 prEN13383-1:2021,

  5. aggregates for railway ballast, as these are specified in prEN 13450‑1:2021,

  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 16907‑2:2018.
