BS 812-124:2009 PDF

Scope: This British Standard describes a test procedure for the determination of the frost resistance of unbound aggregate mixtures that have been compacted to form a cylindrical specimen with a predetermined water content and density. It is applicable to unbound aggregate mixtures used in the construction of roads and other paved areas at a depth that might experience frost penetration. NOTE This method can be used to assess hydraulically bound aggregate mixtures. However, acceptable values of frost heave might differ from those used to assess unbound mixtures. This British Standard includes an option for the use of comparator specimens to confirm that the test chamber is working correctly. The method for the use of comparator specimens is given in Annex B.
