1.1”This test method covers the determination of fracture energy (Gf) of asphalt mixtures using the disk-shaped compact tension geometry. The disk-shaped compact tension geometry is a circular specimen with a single edge notch loaded in tension. The fracture energy can be utilized as a parameter to describe the fracture resistance of asphalt mixtures. The fracture energy parameter is particularly useful in the evaluation of asphalt mixtures with ductile asphalt binders, such as polymer-modified asphalt mixture, and has been shown to discriminate between these materials more broadly than the indirect tensile strength parameter (AASHTO T 322, Ref (1)).2 The test is generally valid at temperatures of 10””’C and below, or for material and temperature combinations which produce valid material fracture, as outlined in 7.4.
