Unbound and hydraulically bound mixtures - Test methods for laboratory reference density and water content. Vibrating hammer1 Scope This European Standard specifies a method for the determination of the relationship between the dry density and water content of a mixture when compacted using a vibrating hammer. This European Standard applies to mixtures used in road construction which contain not more than 30 % by mass retained on the 20 mm test sieve. It is not applicable to mixtures with more than 10 % by mass of the mixture retained on the 40 mm test sieve.
