本技术规范规定了测定水硬混合物对冷冻和解冻循环作用的阻力的试验方法。 所述方法适用于符合EN 14227（所有部分）的水硬性混合物，包括水力稳定的土壤以及该标准所涵盖的强度范围。 当需要时，附录A（规范性）中规定了一种用于确定冻结冻结物体长度变化的方法。 当需要时，在盐的存在下确定水硬混合物的抗冻融性的方法在附录B（规范性）中规定

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).
