scope:

This Technical Specification specifies a test method for the determination of the resistance of a hydraulically bound mixture to the cyclic action of freezing and thawing. The method described is suitable for hydraulically bound mixtures, including hydraulically stabilised soils, in accordance with EN 14227 (all parts) and the range of strengths covered by that standard. When required, a method for determining the change in length of a hydraulically bound subject to freeze thaw is specified in Annex A (normative). When required, a method for determining the freeze thaw resistance of a hydraulically bound mixture in the presence of salt is specified in Annex B (normative).
