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.
