scope:

This European Standard specifies soil treated by cement for the pavement layers of roads, airfields and other trafficked areas and specifies the requirements for its constituents, composition and laboratory performance classification. It provides for the use of aggregates with grading curves, which are not constrained by the limits defined in EN 14227-1 for cement bound granular mixtures. This European Standard does not specify requirements for strength prior to trafficking or frost resistance, which might be covered by requirements at the place of use. Production control recommendations are included in the informative Annex B.
