Abstract:
Yearly, vast numbers of new roads are constituted and existing ones are
restored on a regular basis. The usage of recycled asphalt pavement (RAP) aids
to minimise dependency on natural resources. Hence, organic regenerator such as
waste cooking oil (WCO), have recently been proposed as a sustainable commodity to
enhance the recycling of aged asphalt. This paper summarised the potential ofWCO
being utilized as a renewable commodity in order to boost asphalt binder recycling.
Physical properties tests for instance ductility test, softening point test, penetration
test, flash&fire point test and specific gravity tests; are commonly adopted alongside
test for rheological properties for example dynamic shear rheometer (DSR), Multiple
Stress Creep Recovery (MSCR) tests linear amplitude sweep (LAS) and have all been
adopted to enhance the binder properties. Generally, this paper offers an abbreviation
of the favourable and unfavourable effects of WCO utilisations and indicates that it
could be used as an asphalt rejuvenator that is both environmentally friendly and
able to create high quality pavements.
