摘要: The paper highlights the bitumen part in fatigue of bituminous mixtures, due to cohesive failure binder. A specific test, Repeated Local Fracture Bitumen, has been designed test above. reports analysis results concerning crack initiation and qrowth within sample. observations are confirmed with help acoustic emission. Successive tests performed after different rest period durations show that binder healing depends on temperature duration.
