BS EN 12697 is a European Standard that discusses bituminous mixtures and related test methods. The main objective of the BS EN 12697 series is to ensure that the quality and performance of bituminous mixtures contributes to the structural integrity of your civil engineering works.
BS EN 12697-30 is the 30th part of the multi-series that specifies methods of moulding specimens from bituminous mixtures by impact compaction. Such specimens are primarily used to determine the bulk density and other technological characteristics, e.g. Marshall stability and flow according to EN 12697-34.
BS EN 12697-30 applies to bituminous mixtures (both those made up in a laboratory and those resulting from worksite sampling), with not more than 15 % by mass retained on the 22,4 mm sieve and none on the 31,5 mm sieve.
BS EN 12697-30 on specimen preparation by impact compactor is relevant to:
Impact compaction is a technique that ensures the bituminous mixture offers required levels of density, stiffness and bearing capacity. BS EN 12697-30 provides best industry guidance on moulding specimen by impact compaction.
BS EN 12697-30 walks you through the necessary apparatus, specimen shape and dimensions, specimen preparation and the procedure.
Adopting BS EN 12697-30-compliant guidance on specimen preparation with impact compaction can help demonstrate the reliability and performance of your construction materials, and whether or they are capable of providing required levels of stability and durability. Ultimately, this can help you improve your mix design and quality of materials used for your engineering works.
BS EN 12697-30:2018 supersedes BS EN 12697-30:2012, which is withdrawn. The following is a list of significant technical changes since the previous edition:
