Foreword

This Published Document has been prepared under the direction of Subcommittee B/502/4, Aggregates for unbound and hydraulically bound materials. It is one of nine parts that give guidance on the use and application of a series of European Standards for aggregates. These European Standards were prepared by CEN/TC 154, Aggregates, and have been adopted as British Standards. Conflicting British Standards relating to aggregates will be withdrawn in June 2004.

This part of PD 6682 gives guidance on the use of BS EN 13450 which specifies requirements for aggregates for railway ballast. BS EN 13450 does not supersede any British Standard, but it does specify requirements that necessitated the reissue of Network Rail’s specification for track ballast and stoneblower aggregate (STBSA) [1].

NOTE The STBSA [1] was reissued in 2000 to include Appendix E that gives an updated specification for railway ballast that conforms to BS EN 13450. It is intended that the 2000 edition will be completely revised at a later date to remove all requirements that conflict with BS EN 13450. Users of the STBSA should contact Network Rail for confirmation of revision.¹⁾

Attention is drawn to the fact that BS EN 13450 fully takes into account the requirements of the European Commission mandate M125, Aggregates, given under the EU Construction Products Directive (89/106/EEC) [2].

Guidance on the other European Standards in the series is given in the following parts of PD 6682:

— Part 1: Aggregates for concrete — Guidance on the use of BS EN 12620.
— Part 2: Aggregates for bituminous mixtures and surface treatments for roads, airfields and other trafficked areas — Guidance on the use of BS EN 13043.
— Part 3: Aggregates for mortar — Guidance on the use of BS EN 13139.
— Part 4: Lightweight aggregates for concrete, mortar and grout — Guidance on the use of BS EN 13055‑1.
— Part 5: Lightweight aggregates for bituminous mixtures and surface treatments and for unbound and bound applications excluding concrete, mortar and grout — Guidance on the use of BS EN 13055‑2.²⁾
— Part 6: Aggregates for unbound and hydraulically bound materials for use in civil engineering works and road construction – Guidance on the use of BS EN 13242.
— Part 7: Armourstone — Guidance on the use of BS EN 13383.
— Part 9: Guidance on the use of European test method standards.
