Fatigue damage monitoring and analysis of aged asphalt concrete using acoustic emission technique
Abstract
This paper presents an Acoustic Emission characterization of the damage behavior of asphalt concrete trapezoidal specimen subjected to bending fatigue loading. An experimental fatigue tests campaign is carried out on a damaged asphalt concrete extracted from an in-service highway pavement, built in 2001. Tests were performed in strain controlled mode with an amplitude of 175 µstrain, a loading frequency of 25 Hz, and at 10°C. Failure criteria based on modulus decrease are analysed to determine the fatigue lifespan. Acoustic emission measurements, as a non-destructive technique, are used to investigate the damage and failure processes in the specimen. A network of eight piezoelectric sensors was used to acquire the acoustic signals. Therefore, different fatigue stages are identified based on the temporal evolution of acoustic activity during the tests. Hence, the event's spatial location is presented to show the crack path propagation. The results show that sensors located at the bottom of the specimen register more acoustic emission activity. The locations of acoustic events were in good agreement with the mechanical background calculations.
