This draft 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 draft 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.
