This test method was prepared by the Bituminous Surfacings Technical Group (BSTG) on behalf of the Austroads Pavements Task Force (PTF). Representatives of Austroads, the National Transport Research Organisation (NTRO) and the Australian Flexible Pavement Association (AfPA) were involved in developing and reviewing this test method.
This test method was developed based on research studies conducted in Austroads Project APT1975 Maximising the Life of Sprayed Seals – Future Proofing Binders. The results of the APT1975 project indicated that the fatigue cracking performance of aged bitumen could be ranked by measuring the complex modulus (G*) of a bitumen sample at 15 °C after it had been aged in the laboratory using a pressure ageing vessel (PAV).
This test method is also available as a Word document.
