EN 12697-30:2012 (E) 7 1 Scope This European Standard specifies 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 not more than 15 % by mass retained on the 22,4 mm sieve and none on the 31,5 mm sieve. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The mixture is then compacted into one of the specified impact compactors by the sliding mass falling 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 down to room temperature. 5 Apparatus 5.1 Impact compactor with steel anvil 5.1.1 General 5.1.1.1 The impact compactor with steel anvil (see Figure 1), a machine-driven apparatus shall comprise the components listed in 5.1.1.2 to 5.1.1.9.

NOTE Equipment with eccentric cam (see Figure 1) has been used successfully. 5.1.1.6 Compaction hammer, consisting of a cylindrical guide rod, a sliding mass (see Figure 3), weighing (4 550 ± 20) g, and a foot (see Figure 4), weighing (3 960 ± 20) g. 5.1.1.7 Chain-driven lifting gear, for the sliding mass, designed so that the length of the free fall is (460 ± 3) mm. 5.1.1.8 Device for counting and recording the number of blows. NOTE The number of blows should be counted and added. 5.1.1.9 Linear variable differential transformer (optional), as described in Annex A, for measuring the specimen thickness during compaction for measuring compactibility in accordance with EN 12697-10.
