Examination of regular VG-30 Bitumen Mix and Gilsonite Changed Bitumen Mix

Abstract

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.
