Abstract
Bitumen is the essential and significant constituent of road construction, because of which it has an immense interest. Bitumen is used to bind the different constituents of a mix such as coarse aggregates, fine aggregates and filler. Bitumen is used in the road construction because of its outstanding binding and water proofing capabilities as well as its low cost. The bitumen utilized in this venture is tried for penetration value, ductility value, softening point and viscosity.The utilization of modifiers to work on the performance of hot asphalt mixtures is spreading worldwide and huge number of binders have been created to further develop the attributes of asphalt binders and to make them last more. The main objective of this study is to use Gilsonite as a modifier to improve the properties of the mix and to concentrate on the impact of those properties for example Bulk Specific Gravity (Gm, Voids in air (Va), voids in mineral aggregates (VMA), voids filled by bitumen (VFB), Marshall Stability and Flow value. This experimental work was conducted on VG 30 Grade of Bitumen. In this study, Gilsonite is added to the Bitumen at the rates of 0%, 3%, 6%, 9%, 12% and the results obtained from different tests showed increase in Marshall stability, VMA and decrease in the Bulk Specific Gravity, VFB and Flow Value
