For most countries, the use of recycled asphalt pavement (RAP) has become increasingly common practice as it is both an environmentally and economically desirable option. The aging of bitumen throughout Stocking, blending, transporting and placement on Ways And even service life, the much more severe issues presented through the use of bitumen for pavements. This Research explores A potential of using vacuum residue oil as an effective Rejuvenation agent for aged bitumen, which is a by-product of a condition identical to the original bitumen. As the control binder, Bitumen with Pen 50-60 was selected. At different concentrations, vacuum residue oil was added0 percent, 2.5 percent, 5 percent, 7.5 percent and 10 percent respectively by weight of the total binder in aged bitumen at different concentrations Including penetration, softening point, penetration index ( PI), the features of the renewed bitumen have been tested. As the VR concentration increased Both binding time and temperature were strongly dependent on the ability to merge Of the aged ,Virgin Binders. Reduced mixing temps Decreased diffusion of virgin bitumen and aged binder.
