1 Scope This European Standard describes methods of moulding specimens from bituminous mixtures by impact compaction. Such specimens are primarily used to determine bulk density and other technological characteristics e.g. Marshall stability and flow according to EN 12697-34. This European Standard applies to bituminous mixtures (both those made up in a laboratory and those resulting from work site sampling), with an upper aggregate size not larger than 22,4 mm. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

3 Principle To prepare the specimens, tempered asphalt mix, either freshly mixed according to prEN 12697-35 or sampled on site or plant according to EN 12697-27 is transferred into a specified steel compaction mould. The mixture is then compacted in one of the specified impact compactors by the sliding mass being allowed to fall from a specified height with a specified number of blows within a specified time onto the foot of the hammer, located on top of the asphalt specimen. The specimen is then allowed to cool to room temperature. 4 Apparatus 4.1 Impact compactor with steel anvil 4.1.1 General 4.1.1.1 The impact compactor with steel anvil (see Figure 1), a machine-driven apparatus shall comprise the components listed in 4.1.1.2 to 4.1.1.9. 4.1.1.2 Steel base plate, 15 mm thick and about 600 mm × 610 mm, set horizontally on a firm base. 4.1.1.3 Three feet of equal rigidity in the direction of both compression and shear, fitted with ru
