Because bitumen is such an important and crucial component of road building, it attracts a lot of attention. Bitumen is used to hold coarse aggregates, fine aggregates, and filler together in a mix. Because of its remarkable binding and water proofing characteristics as well as its inexpensive cost, bitumen is employed in road construction. The penetration, ductility, softening point, and viscosity of the bitumen used in this project are all evaluated. Modifiers are increasingly being used to improve the performance of hot asphalt mixtures, and a large variety of binders have been developed to improve the properties of asphalt binders and extend their service life. The main goal of this research is to use Gilsonite as a modifier to improve the properties of the mix, with a particular focus on the impact of properties such as Bulk Specific Gravity (Gm), Voids in Air (Va), Voids in Mineral Aggregates (VMA), Voids filled by Bitumen (VFB), Marshall Stability, and Flow value. The bitumen used in this experiment was VG 30 grade. Gilsonite was added to Bitumen at rates of 0%, 3%, 6%, 9%, and 12% in this study, with results showing a rise in Marshall stability, VMA, and a decrease in Bulk Specific Gravity, VFB, and Flow Value.
