Aggregates for railway ballast

Aggregates for railway ballast

This document specifies the characteristics of aggregates obtained by processing natural or manufactured materials or recycled crushed unbound aggregates for use in the construction of the upper layer of railway track. For the purposes of this document, the aggregate is referred to as railway ballast.
Assessment and Verification of the Constancy of Performance (AVCP) of railway ballast to this document are given in EN 16236.
Aggregates used in construction are meant to comply with the relevant European standards for aggregates. These standards include comprehensive and specific provisions for natural aggregates and recycled railway ballast, dealing with, for example, the stability of certain basalts.
Reused railway ballast is not covered by this document.

Tests for mechanical and physical properties of aggregates - Part 1: Determination of the resistance to wear (micro-Deval)
SIST EN 1097-1:2024

This document specifies the reference method used for type testing and in case of dispute, for determining the resistance to wear of coarse aggregates (main text) and aggregates for railway ballast (Annex A) by abrasion in the micro-Deval apparatus. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the relevant reference method has been established.
This document applies to natural, manufactured, recycled or lightweight (LWA) aggregates.
NOTE   This document does not apply to all types of LWA.
The reference test is performed with the addition of water. Annex B gives details of how the test can be performed without the addition of water.
Annex A specifies the method to determine the resistance to wear of aggregates for railway ballast without abrasive charge.
Annex C specifies the test performed with alternative narrow size fractions.
Annexes D and E specify methods for determining the wear of fine aggregates.
Precision data for the reference test method are given in Annex F.
Annex A is normative and Annexes B, C, D, E and F are informative.
WARNING – The use of this part of EN 1097 can involve hazardous materials, operations and equipment (such as dust, noise and heavy lifts).

SIST EN 933-6:2023

This document specifies the reference method used for type testing, and in case of dispute, for determining the flow coefficient of coarse and fine aggregates. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. Examples of advanced test methods can be found in the Bibliography.
This document applies to coarse aggregate of sizes between 4 mm and 20 mm and to fine aggregate of size up to 2 mm. It does not apply to lightweight aggregates.
NOTE 1   For coarse aggregates between 4 mm and 20 mm, the flow coefficient is linked with the percentage of crushed or broken surfaces of an aggregate and can therefore be used in association with the method specified in EN 933-5. Shape and surface texture characteristics also influence the result.
NOTE 2   Experience of this test has been generally limited to natural aggregates.
Examples of test data sheets are given in informative Annexes A and C.
Annex B (informative) contains precision data.

Tests for general properties of aggregates - Part 3: Procedure and terminology for simplified petrographic description
SIST EN 932-3:2022

This document specifies a basic procedure for the identification of the petrographic type of natural aggregates. It applies for usual requirements for the procedure and terminology for simplified petrographic description. Precise petrographic identification, of technical mineralogy and petrography for civil engineering or specific end uses, requires further examination and is therefore excluded from the scope of this document.
NOTE 1 In principle, a qualified geologist (petrographer), with experience of materials used in civil engineering and aware of the composition of the deposit, has sufficient skills to sample and name the rock.
NOTE 2 For precise petrographic identification and technical requirements for specific applications, a non-exhaustive list of reference literature is given in the Bibliography.
This document applies only to natural aggregates. It is used to describe rocks and sediments. It does not apply to the description and identification of manufactured or recycled aggregates.
Informative Annex A provides guidance on the petrographic nomenclature by giving definitions of simple petrographic terms applicable to rock types used for aggregates.

Tests for mechanical and physical properties of aggregates - Part 6: Determination of particle density and water absorption
SIST EN 1097-6:2022

This document specifies the reference methods used for type testing and in case of dispute, for the determination of particle density and water absorption of normal weight and lightweight aggregates. Other methods can be used for other purposes, such as factory production control, provided that an appropriate working relationship with the reference method has been established. For convenience, some of these other methods are also described in this document.
The reference methods for normal weight aggregates are:
-   a wire basket method for aggregate particles retained on the 31,5 mm sieve (Clause 7, except for railway ballast which uses Annex B);
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve (Clause 8);
-   a pyknometer method for aggregate particles passing the 4 mm sieve and retained on the 0,063 mm sieve (Clause 9).
In Clauses 7, 8 and 9, three different particle densities (oven-dried particle density, saturated and surface-dried particle density and apparent particle density) and water absorption are determined after a soaking period of 24 h. In Annex B, the oven-dried particle density is determined after soaking in water to constant mass.
For aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve, the wire basket method in Clause 7 can be used as an alternative to the pyknometer method in Clause 8.
NOTE 1   The wire basket method can also be used for single aggregate particles retained on the 63 mm sieve.
NOTE 2   The pyknometer method described in Clause 8 can be used as an alternative for aggregates passing the 4 mm sieve and retained on the 2 mm sieve.
The reference methods for lightweight aggregates are:
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 4 mm sieve (Annex C). Three different particle densities (oven-dried; saturated and surface-dried; apparent) and water absorption are determined after pre-drying and a soaking period of 24 h;
-   a method, using a Büchner funnel, for aggregate particles passing the 4 mm sieve (Annex D). The three particle densities and water absorption are determined using a vacuum in the range of 50 mbar to 100 mbar for at least five minutes.
Three other methods for normal weight aggregates can be used to determine the pre-dried particle density, as specified in normative Annexes A and H:
-   a wire basket method for aggregate particles passing the 63 mm sieve and retained on the 31,5 mm sieve (A.3);
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve and retained on the 0,063 mm sieve (A.4);
-   a pyknometer method for aggregate particles passing the 31,5 mm sieve, including the 0/0,063 mm size fraction (Annex H).
NOTE 3   If water absorption is less than about 1,5 %, the apparent particle density can be assessed using the pre-dried particle density method as defined in Annex A.
The quick method in normative Annex E can be used in factory production control to determine the apparent particle density of lightweight aggregates.
The method in informative Annex F can be used to determine the particle density and water absorption of aggregate particles passing the 4 mm sieve.
Data on the density of water at various temperatures is specified in normative Annex G.
Guidance on the significance and use of the various density and water absorption parameters is given in informative Annex I.
Precision data are presented in informative Annex J.
