DIN EN 12697-33 PDF Download

The DIN EN 12697-33 standard outlines the procedures for compacting parallelepipedal specimens of bituminous mixtures. These specimens are either used directly for subsequent testing or are cut to obtain test specimens. The standard provides two options for preparing the specimens: controlled compaction energy or achieving a specified volume and air voids content.

The standard covers three methods of compaction: the pneumatic tyre method, the steel roller method, and the steel roller sector method. These methods entail using specific equipment to compact the bituminous mixtures into slabs. The standard is applicable to both laboratory-manufactured bituminous mixtures and those produced in a mixing plant.

By specifying the compaction methods and requirements for bituminous mixtures, this standard ensures consistent and accurate testing of these materials. Implementation of this standard promotes reliable evaluation and comparison of different bituminous mixtures, assisting in the development of high-quality pavement materials.
