Phạm vi áp dụng / Scope of standard

This test method covers the determination of fracture energy density of asphalt binder by means of a direct tension test. For evaluation of relative cracking performance, it is recommended that this test procedure be used with asphalt binder aged using T 240 (RTFO) plus R 28 (PAV). However, this test can be used for determination of binder facture energy for any binder including any aged (RTFO plus PAV or PAV only) neat or modified binder and asphalt binder extracted and recovered from pavement. The test apparatus is designed for testing within the intermediate temperature range, from 0°C to 25°C.
