适用范围：This British Standard describes a test procedure for the determinationof the frost resistance of unbound aggregate mixtures that have beencompacted to form a cylindrical specimen with a predetermined watercontent and density.It is applicable to unbound aggregate mixtures used in the constructionof roads and other paved areas at a depth that might experience frostpenetration.NOTE This method can be used to assess hydraulically bound aggregatemixtures. However, acceptable values of frost heave might differ fromthose used to assess unbound mixtures.This British Standard includes an option for the use of comparatorspecimens to confirm that the test chamber is working correctly. Themethod for the use of comparator specimens is given in Annex B.
