AASHTO Designation: T 315-08 pdf free download

1.1.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 l 00 Pa to 10 MPa.

This range in modulus is typically obtained between 6 and 88°C at an angular frequency of IO rad/s.

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.

1.2.This standard is appropriate for unaged material or material aged in accordance with T 240 and R28.

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