Abstract:
This paper focused on the short-term ageing influence on the creep and recovery characteristics of neat and SBS modified asphalt binders at two different stress levels. Using the MSCR test conducted on dynamic shear rheometer (DSR), it can be concluded that the RTFOT short-term ageing process was observed to decrease the nonrecoverable compliance (J(nr)) and increase the average recovery percent (R) for almost all binders, which was more notable at a high stress level especially for SBS modified binders. Additionally, stress level applied in test played a key role in evaluating the viscoelastic properties of different asphalt binders, and SBS modified binder exhibited more stress sensitive than neat binders.
