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.

sweep plan

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,
— L = 600 mm, l = 400 mm, h = 150 mm or h = 200 mm.

For moulds 600 mm × 400 mm × 150 mm or 600 mm × 400 mm × 200 mm, dimensions are those of the

upper part.

In order to facilitate demoulding, moulds may have the shape of a truncated pyramid within the interior

dimension ranges specified in order to release the specimen.

Other dimensions may be used, according to the requirements of specific test methods.

5.1.2 A device to compact the bituminous mixture which shall:

— enable application of an adjustable load, F, in range 1 kN ± 10 % to 10 kN ± 5 %, onto the wheel(s);

— comprise of one or more wheels equipped with threadless tyres of 400 ⤬ 8 size;
— enable translation of the rolling load at constant velocity, V ± 10 %;

— comprise a system for positioning wheel(s) along the different axes of compaction according to

predetermined set values for (a ± 20 mm);
— enable operation in blocked axis and freed axis modes;

— comprise a system capable of periodically bringing the surface flush with the upper edge of the

mould during compaction;

— one or more blocks of a suitable size (only required if the required thickness of the slab, e, is less

than the height of the mould, h).

5.2 Methods using a smooth steel roller
5.2.1 Smooth steel roller

5.2.1.1 One or more moulds with specified interior dimensions (length L and width l) to ± 1 mm.

5.2.1.2 A device to compact the bituminous mixture in the mould.

It may be either a mechanical self-propelled rolling wheel static compactor with forward-reverse

control, or a hand driven roller, or a laboratory device, which simulates the operation of a rolling wheel

static compactor such as a segmented roller. The wheel shall be able to move back and forth on the

mixture in the mould, or the mould shall be placed on a table that moves back and forth beneath a

rotating roller.

When the method is used to prepare slabs at a specified volume or air voids content, a vibrating roller

or table may also be used.

!The device shall enable application of a static load, F, according to Formula (1):

26−
F ≥Wl·· D ⋅10 (1)
where
F is the load, applied onto wheels or rollers, in newtons (N);
W is the roller compaction parameter in (kN/m ).
For the application on asphalt mixtures: W = 10 kN/m
l is the interior width of mould, in millimetres (mm);
D is the diameter of the wheel(s) or roller, in millimetre (mm).
The diameter of the steel roller, D, shall be in the range 350 mm to 1 100 mm.

When the method is used to prepare slabs at a specified volume or air voids content, for a mass as

specified in 6.1, the width of the steel roller, b, shall be greater than:

— the internal width of the mould, l, if the roller compactor is not equipped so that compaction stops

when the desired height of the slab is reached, or

— the internal width of the mould, l, minus 8 mm if the roller compactor is equipped so that

compaction stops when the desired height of the slab is reached.

The load, F, shall be of such magnitude that the specified volume or air voids content is achieved at a

number of roller passes between 10 and 50.

When the method is used to prepare slabs under controlled compaction energy, the width of the steel

roller shall be equal to the interior width of the mould minus (10 ± 5) mm.
5.2.2 Steel roller used on wheel fitted with pneumatic tyres
5.2.2.1 One or more moulds as specified in 5.1.1.

5.2.2.2 A device to compact the bituminous mixture which shall conform to the device in 5.1.2 and

comprise, if required, a smooth metal cylinder of diameter, D 400 mm to 800 mm, thickness between

4 mm and 8 mm, and width equal to the interior width of the mould minus (5 ± 2) mm.

5.3 Method using a steel roller sector
5.3.1 General

The roller sector compaction device consists of a rectangular steel compaction mould and a roller sector

which replicates a smooth compaction roller drum. Figure 2 shows an example for the roller sector

compaction device.
5.3.2 Roller sector

The surface of the roller sector shall be heatable to a temperature as specified in 6.2. The length and

width of the roller sector shall comply with the dimensions of the compaction mould. The roller sector

is attached to the loading device in the centre of the steel sector.

The radius of the roller (distance of sector centre to sector surface) shall be between 350 mm and

550 mm.
5.3.3 Compaction mould

Rectangular compaction mould on which the roller sector can exert an alternate rotation maintaining

vertical loading of controlled force. The inner surfaces of the mould shall be heatable to the temperature

required for use in 6.2.
5.3.4 Loading device

Loading device allowing the vertical movement of the loading piston in controlled force and controlled

deflection mode. The load capacity depends on the dimensions of the compaction mould. The piston

shall allow vertical movements to compact the plate to the required thickness.
5.3.5 Demoulding facilities

Facilities allowing the demoulding of the asphalt slab after compaction in by non-invasive ways.
