CEN/TC 256/SC 1/WG 16 - Sleepers and bearers

This document is applicable to Resilient Elements for Floating Slab system (REFS) – Elements used in floating slab and defines the test procedures and their acceptance criteria.
The document covers not only those parameters related to the effectiveness of a track structure in mitigating vibrations, that is, to reduce the emission of vibrations and structure-borne noise, but also the parameters that are needed for the static analysis and for the verification of track safety.
Floating slab track systems in the form of track base plates and track troughs are individual solutions in which there is considerable variation in the engineering design and the types of resilient elements used. For this reason, a floating slab track system is always an individual engineering solution and therefore, it is not possible to define all specific conditions for the resilient elements in the present document.
The most typical types of resilient elements are:
—   Full surface bearings,
—   Strip bearings,
—   Discrete bearings (including the helical steel spring element),
—   Vertical bearings.
This document provides particular information in the following areas:
—   test methods, test arrangements and acceptance criteria,
—   data supplied by the purchaser and by the supplier,
—   definition of general process of design approval tests,
—   definition of routine tests.
This document defines the specific test procedures for REFS:
—   stiffness tests,
—   fatigue tests,
—   severe environmental condition test.
This document also sets out procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance procedures. This document does not, however, contain requirements pertaining to the functions of Resilient Element for Floating Slab system. It is the responsibility of the purchaser to define these requirements and to choose the optional tests.

This standard gives special criteria for the design of concrete sleepers and bearers as track components. The design methods in the Eurocode do not apply to these concrete elements.
All track parameters to be taken into account for the design of sleepers and bearers are detailed in this standard. Information is given on these parameters so that they can be used as inputs for the design calculation process. It is the responsibility of the purchaser to calculate or determine all track parameters used in this standard.

-   test methods, test arrangements and evaluation criteria of concrete sleepers and bearers with Under Sleeper Pads;
-   data supplied by the purchaser and by the supplier;
-   definition of general process of design approval tests;

-   pull-out test;
-   severe environmental condition test.
This standard also sets out procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance procedures. This standard does not, however, contain requirements pertaining to the properties of Under Sleeper Pads. It is the responsibility of the purchaser to define these requirements

This part of the EN 13230 series defines technical criteria and control procedures which need to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, twin-block reinforced sleepers, bearers for switches and crossings, and special elements for railway tracks.
The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use, they are also exposed to frost damage and to moisture, which can result in detrimental chemical reactions within the sleeper.
In this standard mechanical tests are defined which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition, controls are placed on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage.
