Phạm vi áp dụng / Scope of standard

This test method covers the determination of the dynamic shear
modulus and phase angle of asphalt binder when tested in dynamic
(oscillatory) shear using parallel plate test geometry. It is
applicable to asphalt binders having dynamic shear modulus values
in the range from 100 Pa to 10 MPa. This range in modulus is
typically obtained between 5°C and 85°C. This test method is
intended for determining the linear viscoelastic properties of
asphalt binders as required for specification testing and is not
intended as a comprehensive procedure for the full characterization
of the viscoelastic properties of asphalt binder.

This standard is appropriate for unaged material or material
aged in accordance with n40, PPI, or "240 and PP1.

Particulate material in the asphalt binder is limited to
particles with longest dimensions less than 250 µm.

This standard may involve hazardous materials, operations,
and equipment. This standard does not purport to address all of the
safety problems associated with its use. It is the responsibility
of the user of this procedure to establish appropriate safety and
health practices and to determine the applicability of regulatory
limitations prior to use.
