Abstract:
The performance evaluation of various aged binders changed with Waste Cooking Oil
(WCO) and Waste Engine Oil (WEO) encompasses a comprehensive investigation into the
effects of short-term and long-term aging on binder properties. Short-term aging typically
mirrors the immediate changes experienced by binders upon production, while long-term
aging entails prolonged openness to environmental factors, simulating real-world
conditions. Through thorough testing procedures including penetration, softening point,
pliability, flash point, and thickness tests, the review examines the evolution of binder
characteristics after some time, elucidating the impact of aging and modification with
WCO and WEO. Perceiving the research gap encompassing broadened long-term aging,
this study embarks on an exploration of binder behavior beyond conventional aging
durations. By broadening the aging time frame, the research aims to uncover nuanced bits
of knowledge into the durability and performance of changed binders, making up for a
critical shortcoming in momentum asphalt and pavement engineering literature. Through
systematic analysis and comparison with short-term and long- term aged binders, the
review looks to elucidate the transformative effects of extended long-term aging on binder
properties, revealing insight into optimal modification strategies and enhancing the
sustainability and versatility of asphalt pavements. This endeavor vows to contribute
significantly to the advancement of asphalt binder innovation, paving the way for more
strong and environmentally conscious infrastructure solutions. In this review, an
investigation was conducted to determine the optimal proportions of waste cooking oil and
waste engine oil for short-term, long-term, and extended long-term aging of bitumen. The

research included aging bitumen samples throughout a period of time ranging from 5 to 17
hours with 3-hour intervals, allowing for a comprehensive assessment through
conventional tests and rheological analyses. By systematically varying the percentages of
waste cooking oil and waste engine oil, the review aimed to pinpoint the best combination
for enhancing bitumen aging characteristics. The obtained results from these tests educated
the selection regarding ideal percentages, directing further analysis in terms of chemical
composition and minuscule properties for a careful evaluation of expanded long-term aged
asphalt. Consequently, chemical analysis and infinitesimal examinations were performed
to dive further into the effects of the chose waste oil percentages on the lengthy long-term
aging of asphalt. The chemical analysis aimed at recognizing molecular changes and the
overall composition of the aged asphalt, revealing insight into potential alterations in its
structural uprightness. Concurrently, minuscule analysis allowed for a detailed
investigation of the asphalt's microstructure, giving bits of knowledge into the impact of
waste cooking oil and waste engine oil on the formation of microcracks, aggregates, and
other relevant features. This consolidated approach allowed for a comprehensive
understanding of the impact of waste oil incorporation on the drawn out extended longterm aging of asphalt, contributing valuable experiences to the field of asphalt materials
and sustainable waste utilization.
