The purpose of this standard is to measure the dynamic shear modulus and phase angle of asphalt. It applies to dynamic shear modulus values in the range of 10 ^ -4 MPa to 10 MPa, and is generally performed between 5 ° C and 85 ° C. It applies to unaging asphalt or to asphalt obtained by swirl/spin film oven test or accelerated weathering test. For asphalt containing particles, it is only applicable if the particle size is less than 250 μm. The standard refers to a series of normative documents, including asphalt sampling method, asphalt swirl/spin film oven test method, asphalt accelerated weathering test method, etc. The asphalt is defined as a product obtained by distillation, oxidation, blending or modification of petroleum or petroleum residue as raw materials.
