BS EN 14227-3:2013EN 14227-3:2013 (E) 6 1 Scope This European Standard specifies fly ash bound granular mixtures for roads, airfields and other trafficked areas, and specifies the requirements for their constituents, compo
29、sition and laboratory performance classification. In this European Standard, fly ash refers to siliceous or calcareous fly ash complying with EN 14227-4. Where fly ash is part of cement conforming to EN 197-1 or hydraulic road binder conforming to EN 13282-1 and EN 13282-2, then reference should be
30、made to EN 14227-1 or EN 14227-5 respectively. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
