Aggregates for railway ballast - Part 1: Characteristics
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:
— 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,
— recycled aggregates, with particle densities less than 1,50 Mg/m3,
— aggregates with a nominal upper size greater than 90 mm,
— armourstone, as this is specified in prEN 13383-1:2021,
— aggregates for construction works, as these are specified in prEN17555-1:2021,
— 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,
— use of aggregates as soil,
— use of aggregates in earthworks, as these are specified in EN 16907:2018, Parts 1 to 6.

The most significant technical changes compared to EN 13450:2002 include:
a) Complete structural and editorial revision;
b) Harmonization of vocabulary and Annex ZA to be consistent with Regulation (EU) 305/2011 on
construction products (CPR);
c) Improvement of the consistency with the aggregate standard EN 17555-1;
d) Unification of definitions which were common across aggregate standard EN 17555-1;
e) Updating and improving references to supporting test methods;
a) Modification of the definition of “recycled railway ballast”;
f) Modification of classes for grading;
g) Modification of Tables 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, due to changes in the class names and due to the
introduction of new classes for flakiness index, percentage of crushed particles, Los Angeles
coefficient, resistance to impact and micro Deval coefficient;
h) Addition of new Clauses 4.1.2.4 “Percentage of crushed particles”, 4.5.4 “Freeze-thaw resistance”;
i) Addition of new Tables 11, 12, 13, 14, and 15;
j) Revision of Clause 4.5.5 “Sonnenbrand”;
k) Removal of clauses referring to dangerous substances;
l) Removal of simple petrographic description from the characteristics and inclusion instead under the
marking, labelling and packaging clause;
m) Removal of Annex A (informative) “Sampling railway ballast at the construction site either from a
railway wagon or from the track”, Annex B (informative) “Guidance on interpretation of results when
samples of railway ballast have been taken from railway wagon or from track”, Annex C (normative)
“Conditions to be applied to the test procedure specified in EN 1097-2:2010 for testing the Los
Angeles coefficient of railway ballast”, Annex D (normative) “Conditions to be applied to the test
procedure specified in EN 1097-2:2010 for testing the Impact value of railway ballast”, Annex E
(normative) “Conditions to be applied to the test procedure specified in EN 1097-1:2011 for
determination of the resistance to wear (micro-Deval) of railway ballast”; Annex F (normative)
“Conditions to be applied to the test procedure specified in EN 1367-1 for determination of the
