Behaviour of Hot Mix Asphalt Incorporating Untreated and Treated Waste Cooking Oil

The recyclability of waste cooking oil (WCO) as rejuvenator for aged asphalt mixture improved the serviceability pavement itself. Currently, researcher is exploring new potential WCO modifier binder modification. However, issue compatibility properties in modification with arises since poor mechanical performance globally recorded thus reflected weakness adhesion bonding inside material. Basically, superior asphaltic concrete exhibited good between binder-aggregates interaction bituminous mixture. In fact, high adhesiveness binding affected by chemical theory which mostly related to polarity factor. Therefore, it vital conduct analysis and microstructure observation obtain a comprehensive understanding polar group behaviour internal structure material that influencing structural arrangement excellent capable improving Hot Mix Asphalt (HMA). identification composition determination was identified using Gas Chromatography-Mass Spectrometry (GC–MS). Meanwhile, measurement binder-aggregate interactions observed Field Emission Scanning Electron Microscope (FESEM) physically resulting conducting resilient modulus test, dynamic creep test indirect tensile strength (ITS) test. Results showed incompatibility characteristic revealed untreated conventional (PEN 60/70) based on non-polar compounds interaction. Thereby, exhibits existence gap void HMA through FESEM visualization hence affecting
