The bituminous binder plays an important role in flexible pavement performance. Aging of the binder leads to the deterioration of the flexible pavement due to prolonged exposure to weather condition. Aging in bitumen binder normally resulted from the weathering of the binder due to oxidation. Physical and Chemical properties of the bituminous binder changes due to aging process and the binder becomes hardened. Due to hardening of the binder, gradual loss of visco-elastic properties of the binder occurs. Thus, the flexibility of the asphaltic pavement reduces as the bitumen binder ages. The polymer modification of the binder can improve the quality of binder and enhance the physical, chemical and rheological properties of the binders used for the pavement construction. In this paper, Ethylene Propylene Copolymer is used to modify bituminous binder. Thin Film Oven Test (TFOT) is conducted inthe laboratory to simulate short term aging at high temperature. The physical properties of VG-30 grade bitumen with and without Ethylene Propylene Copolymer are found for un-aged and TFOT aged sample. The results from the laboratory tests indicates that short term aging of the bitumen shows the physical hardness of the binder properties after simulating Thin Film Oven Test (TFOT), reducing binder penetration, increasing softening point and increasing elastic recovery.
