Bitumen and bituminous binders - Determination of complex shear modulus and phase angle - Dynamic Shear Rheometer (DSR)
This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear.
From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus.
This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber).

1 Scope
This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the
rheological properties of bituminous binders. The procedure involves determining the complex shear
modulus and phase angle of binders over a range of test frequencies and test temperatures when tested
in oscillatory shear.
From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and
frequency are calculated, as well as the components G' and G” of the complex shear modulus.
This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test
procedure in accordance with this document is not applicable for bituminous binders with particles
larger than 250 μm (e.g. filler material, granulated rubber).

3.1
shear strain controlled mode
rheometer control mode where a demand angular displacement is applied to the specimen and the
corresponding torque is measured
Note 1 to entry: Using the shear strain factor of the measuring geometry, a specimen shear strain can be calculated
from the applied angular displacement. Using the shear stress factor of the measuring geometry, a specimen shear
stress can be calculated from the measured torque. Additional corrections can be applied to calculate true specimen
shear strain and true specimen shear stress. These corrections are automatically carried out by the instrument
software and are not the responsibility of the operator.
3.2
shear stress controlled mode
rheometer control mode where a demand torque is applied to the specimen and the corresponding
angular displacement is measured
Note 1 to entry: Using the shear stress factor of the measuring geometry, a specimen shear stress can be calculated
from the applied torque. Using the shear strain factor of the measuring geometry, a specimen shear strain can be
calculated from the measured angular displacement. Additional corrections can be applied to calculate true
specimen shear stress and true specimen shear strain. These corrections are automatically carried out by the
instrument software and are not the responsibility of the operator.
