Modification of asphalt to improve the overall performance of pavements has been the focus of numerous researchers in recent years. This paper discovered whether the use of chemical additives namely Advera® is possible to influence the physical and chemical bonding of asphalt binder grade 80/100 subjected to different aging conditions. The fundamental characteristics of modified binder containing 4%, 5%, 6% and 7% of Advera® were determined by conventional methods while chemical characterisation was assessed by conducting Fourier tTransform iInfrared sSpectroscopy (FTIR). With the aid of image tool, scanning electron microscopy (SEM) was employed to study the surface texture and morphology of Advera® modified binder.The results indicated that, the Advera® modified binder had improved the physical and chemical properties over base binder for both aging condition. The SEM images show that the microstructure of Advera® modified asphalt binder changed compared to the control asphalt binder. A good dispersion of Advera® particles in the asphalt binder matrix is observed. This is proved by the FTIR results which indicate that the stretching of hydroxide is increase when the Advera® is added in the virgin asphalt binder.
