Summary:ABSTRACT Huge accumulations of Recycled asphalt pavement (RAP), scarcity of bitumen obtained from natural resources, RAP causing environmental pollution, and increased construction of flexible pavement all over the world led the researchers to reuse the improved aged bitumen by modifiers. Hence, in this research, the reclaimed aged asphalt improved by ABS (5% weight of virgin bitumen) was partially replaced by virgin bitumen (10 to 60% with an increment of 10%) used in the asphalt mix, and mechanical properties such as stability, flow, rutting resistance, fatigue life, Indirect Tensile strength, and resilient modulus were investigated. The research concluded that the aged reclaimed asphalt containing 5% ABS can be partially replaced up to 30% by conventional virgin bitumen, exhibiting better performance without compromising the mechanical properties of the asphalt mix.
