Abstract

Sustainable innovation in road construction encourages the use of recycled materials, such as Reclaimed Asphalt Pavement/RAP, as an alternative to reduce dependence on new materials and minimize negative environmental impacts. However, RAP materials generally undergo an aging process that causes a decrease in viscoelastic properties, an increase in stiffness, and a decrease in resistance to cracking and deformation. To address these issues, rejuvenators produced from biomass waste - such as rice husks, bagasse, palm oil waste, and other agricultural residues - are being developed as environmentally friendly solution in restoring the rheological properties of RAP asphalt and improving the performance of the asphalt mixture. The results show that plant-based rejuvenators containing lignin with a chemical structure consisting of carbon, hydrogen, oxygen elements, and have active groups such as aromatic ring structures, aliphatic and aromatic hydroxyl groups, and quinone groups very similar in structure to asphalt can rebalance the proportion of malten and asphaltene fractions in aged asphalt. The use of bio-rejuvenators provides performance that results in a decrease in the complex modulus (G⁎) value and an increase in the phase angle (δ), indicating improved flexibility and reduced stiffness of the asphalt, approaching the characteristics of new asphalt. Furthermore, the addition of biojuvenators also positively impacts resistance to rutting and fatigue, while enhancing the workability of the asphalt mixture, especially in low-temperature applications.

Abstract

The increasing demand for pavement materials necessitates more sustainable solutions, one of which is the utilization of Reclaimed Asphalt Pavement (RAP) containing aged asphalt from recycled layers. However, the high incorporation of RAP often faces challenges such as increased stiffness, reduced ductility, and degradation of viscoelastic properties due to aging. In this context, waste cooking oil (WCO) has attracted significant attention as an eco-friendly and cost-effective rejuvenator. This study presents a systematic literature review on the application of WCO in RAP mixtures, focusing on its chemical characteristics, effects on rheological and mechanical properties, implementation challenges, and performance enhancement strategies through chemical modification and additive incorporation. The findings indicate that WCO effectively reduces binder viscosity, improves flexibility, enhances low-temperature cracking resistance, and extends the fatigue life of RAP mixtures. However, excessive WCO content may reduce Marshall stability and rutting resistance. Synergistic approaches such as polymer addition, nano-material incorporation, or chemical pre-treatment have proven effective in addressing these limitations. This review highlights WCO’s potential as a sustainable rejuvenator while emphasizing the need for further research on dosage optimization, quality standardization, and long-term performance evaluation to support large-scale industrial implementation.
