1 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.
