| Summary: | The stiffness of aged binder is highly contributed to the workability problem.
Rejuvenating agent such as waste engine oil (WEO) is one of the sustainable modifiers that can be
used to improve and attain the desired performance of the aged binder. However, concern arises on
the consistency of the engine oil properties due to its unknown history usage. This study focused on
the rutting properties evaluation of the partial aged binder integrating with engine oil (new and
waste sources) using Dynamic Shear Rheometer (DSR). The findings showed that, the addition of
WE0 affects the rutting performance under ageing condition. From the isochronal curve, the
complex modulus, G* of the rejuvenated binder was found lower than the aged binder at un-aged
condition. However, after ageing process, the stiffness of the rejuvenated binder was increased and
the phase angle, 6 decreased obviously compared to virgin binder. The critical temperature of the
binder was not differing substantially particularly under ageing. Meanwhile, the ageing index
rutting factor (AIRF) clearly summarised that the rejuvenated binder with WE0 with higher mass
loss more susceptible to ageing. |
