CEN/TC 154 Aggregates
91.100.15 Mineral materials and products
This European Standard specifies the properties of aggregates obtained by processing natural or manufactured materials or recycled crushed unbound aggregates for use in construction of railway track. For the purposes of this standard, the aggregate is referred to as railway ballast.
It provides for the evaluation of conformity of the products to this European Standard.
NOTE The requirements in this European Standard are based upon experience with aggregate types with an established pattern of use. Care should be taken when considering the use of aggregates from sources with no such pattern of use, e.g., recycled aggregates and aggregates arising from certain industrial by-products. Such aggregates, that should comply with all the requirements of this European Standard, could have other characteristics not included in Mandate M 125 (as amended) that do not apply to the generality of aggregate types with an established pattern of use and when required, provisions valid at the place of use can be used to assess their suitability.
