Abstract

Results from acoustic emission (AE) tests of asphalt binder specimens with different strengths and aging are presented and discussed. The asphalt binder specimens were molded to granite substrates and thermally loaded by submitting the specimens to temperatures ranging from 15°C to -50°C. It was observed that the acoustic emission activity resulting from the thermal contraction of asphalt binders is sensitive to stiffness typified by different binder type and level of aging. Based upon the acoustic emission activity, the fracture strength of the asphalt binders is estimated using a rate process analysis. The fracture strength estimated using the rate analysis compare relatively well with published values.
