Bituminous mixtures - Test method - Part 33: Specimen prepared by roller compactor

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.

4 Principle
A given mass of bituminous mixture is compacted in a rectangular mould under a load applied by a
smooth steel roller or its sector or equivalent, or by one or more wheel(s) fitted with pneumatic tyres.
The smooth steel roller may run directly on the bituminous mixture, or on a number of vertical sliding
plates, which apply a kneading action to the mixture. The wheel(s) or roller performs passes at constant
velocity, according to a specified sweep plan if applicable.
5 Apparatus
5.1 Method using a wheel or two wheels fitted with pneumatic tyres
5.1.1 One or more moulds with specified interior dimensions ± 2 mm. Usual dimensions are:
— L = 500 mm, l = 180 mm, h = 100 mm or h = 50 mm,
or
— L = 600 mm, l = 400 mm, h = 150 mm or h = 200 mm.
