This European Standard specifies the properties of aggregates obtained by processing natural or manufactured or recycled materials for hydraulically bound and unbound materials for civil engineering work and road construction. It covers aggregates having an oven dried particle density greater than 2, 00 Mg/m3. It also covers recycled coarse and all-in aggregates with particle densities greater than 1, 50 Mg/m3 with appropriate caveats and recycled fine aggregate with stated caveats. Use of aggregates as soil is not covered by the present standard. Aggregates used in construction shall conform to all the requirements of the relevant European Standards for aggregates. These standards include comprehensive and specific requirements for natural aggregates, iron and steel making slag and recycled aggregates, dealing with, for example, the stability of certain basalts, the expansion of certain slags and the constituents of recycled aggregates. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Regulations.
