Abstract

The article provides a comprehensive overview of the research utilizing waste engine oil (WEO) in asphalt binders for multiple application purposes and the economic and environmental implications. It covers the various types and sources of WEO for information on their characteristics and the process of preparing the WEO-asphalt binders. The study collects the effects of WEO in different applications, including asphalt modification, aged asphalt rejuvenation, self-healing asphalt agents, and WEO composites. It also discusses work on the economic and environmental appraisal associated with a wide WEO utilization. WEO exhibits both positive and negative influences on asphalt properties. Generally, it improves the performance of asphalt at low temperatures, specifically in terms of reducing issues like thermal cracking and enhancing fatigue resistance. However, it may have a negative impact on the performance of modified asphalt binders at high temperatures. WEO, due to its high concentration of light components, enhances the overall performance of aged asphalt. The integration of WEO and the reclaimed asphalt binders can enhance crack resistance, which however highly relies on the added WEO quantity. Future research should be prioritized to understand the comprehensive impact of WEO on reclaimed asphalt binder for the compatibility between the rejuvenator compound and the reclaimed aged asphalt, and the effect of WEO on the durability of the modified asphalt mixes. In addition, field investigation and analyse are also required for a bigger, inclusive and more detailed picture of the economic and environmental impacts.
