scope:

This document specifies the methods for compacting parallelepipedal specimens (slabs) of bituminous mixtures, to be used directly for subsequent testing, or from which test specimens are cut.

For a given mass of bituminous mixture, the specimens are prepared either under controlled compaction energy, or until a specified volume and therefore air voids content is obtained.

This document describes the following methods of compaction:

- method using a wheel or two wheels fitted with pneumatic tyres;

- methods using a steel roller, which includes 3 different procedures:

- steel roller;

- steel roller used on wheel fitted with pneumatic tyres;

- steel roller running on vertical sliding steel plates;

- method using a steel roller sector.

This document is applicable to bituminous mixtures manufactured in the laboratory or in a mixing plant.
