3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1
short-term ageing
ageing that the binder experiences during the production of asphalt mixtures
3.2
long-term ageing
ageing that the binder experiences during its service life in asphalt pavements
3.3
stabilisation
conditioning of the binders from bituminous emulsions, cut-back or fluxed bitumens to produce residual
binders for further determination of their characteristics
Note 1 to entry: The conditioning procedure is described in EN 13074-2.
3.4
short-term ageing conditioning
conditioning that the binder experiences during the method according to EN 12607-1, EN 12607-2 or
EN 12607-3
3.5
accelerated long-term ageing conditioning
simulated long-term ageing that the binder experiences during the ageing procedure described in this
document
Note 1 to entry: This procedure is called “accelerated” because the ageing of the binder during long-term service
life is speeded up for laboratory purposes by use of high pressure and high temperature.
Note 2 to entry: In the case of hot mix asphalt binders, the long-term ageing conditioning is carried out on binders
that have already been conditioned through short-term ageing conditioning procedures (3.4).
Note 3 to entry: In the case of bituminous emulsion, cut-back and fluxed bitumens, the long-term ageing
conditioning is carried out on binders after a stabilization procedure (3.3).
4 Principle
A static film of binder is heated to a specified temperature under a specified air pressure for a given period
of time. This is done in order to simulate the changes occurring to the binder within the pavement during
service life.
The effects of this ageing procedure are evaluated on the conditioned binders after PAV.
NOTE The ageing of binders during service life can be affected by ambient temperature and air pressure as
well as by a combination of associated variables such as volumetric mixture proportions, mixture permeability,
aggregate properties and other factors. This test is intended to provide an evaluation of the relative ageing
behaviour of binders under specified conditions, but it cannot account entirely for bituminous application variables
or provide relative resistance to ageing at in-service conditions.
5 Apparatus
Usual laboratory apparatus and glassware, together with the following:
5.1 PAV equipment, designed to operate with an air supply at (2,1 ± 0,1) MPa between 80 °C and
115 °C. Either 5.1.1 or 5.1.2 are applicable as individual parts or as an integrated system (see Figure 1).
5.1.1 Pressure vessel, which shall be made from stainless steel and shall have internal dimensions
adequate to contain a pan holder capable of holding a number of containers (according to requirements
and dimensions given in EN 12607-2:2014, 4.3).
The bottom of the pressure vessel shall be such that the containers are held in a horizontal position with
the binder evenly distributed across the diameter of the container in equal binder film thickness. A
drawing showing a possible configuration of the vessel pan holder and containers and specifying
dimensional requirements is shown in Figure 2.
Other pressure vessels of different internal dimensions can be used provided that the operating
conditions can be satisfied. In such cases, the containers used may differ from the standard dimensions
given in EN 12607-2.
The pressure vessel may be a separate unit to be placed in a forced draft oven or an integral part with a
temperature control system.
The PAV equipment shall have an integrated, built-in temperature control system that is capable of
meeting the conditions given in 5.1.2 a) and b).
SAFETY PRECAUTIONS — The pressure vessel operates at high temperatures and high pressures. All
safety guidelines issued by equipment manufacturers shall be adhered to.
5.1.2 Forced draft oven, to be used with 5.1.1 and which is capable of:
a) bringing the loaded pressure vessel to the desired conditioning temperature ± 1,0 °C, as recorded by
a suitable temperature measuring device inside the vessel, within two hours after loading the
pressure vessel into the oven;
b) maintaining the conditioning temperature at ± 1,0 °C.
The oven shall have sufficiently large interior dimensions to allow forced air to freely circulate within the
oven and around the pressure vessel. The oven shall contain a stand or a shelf, which supports the loaded
pressure vessel in a level position above the lower surface of
