Bitumen aging is responsible principle factor for the deterioration of bitumen pavements. It is accountable for deterioration of physical and chemical properties of bitumen binder. In this present study cement is used in various percentages (0%, 1%, 1.5%, and 2%) as modifier in 60/70 grade bitumen. The effect on physical properties in terms of penetration, softening point and viscosity before and after aging are measured. The binders are aged using Thin Film Oven Test (TFOT).The results showes that before aging softening point, viscosity increases and penetration decreases with increasing percentage of filler material. After aging penetration of aged binders decreases than unaged binders but decrease in penetration value is more for binder having less amount of filler material. Decrease in penetration value is less for binder having 2% cement as filler than other binders after aging. Viscosity value is more for aged binders than unaged binders. Viscosity value is increases as percentage of filler increases for aged binders. For binder having 1% cement has less increase in viscosity value than other binders. Softening point increases of aged binders than unaged binders. Increase in softening value is less for binder having 2% cement as filler than other binders after aging.
