Abstract : Bituminous mixtures are widely used in flexible pavement construction worldwide, combining bitumen as a binder with mineral aggregates. However, these pavements often underperform in hilly areas. Research has explored additives and bitumen modifications, with Fibre additions to asphalt enhancing strength and cohesion between aggregates and the binder. Meanwhile, industrial steel slag, an environmental concern, is a byproduct of steel manufacturing. It can replace natural aggregates in concrete, addressing scarcity and environmental concerns. This report presents key studies on steel slag's use as coarse aggregate and its impact on concrete strength, durability, density, and workability. It also discusses steel slag properties and potential applications, along with the advantages of adding various fibers to bituminous concrete. In the context of this research, we have examined bitumen contents at 5%, 6%, and 7% of the total specimen weight. Additionally, we have substituted steel slag for aggregates at levels of 20%, 40%, and 60%, and incorporated glass Fibre at proportions of 0.4%, 0.7%, and 1% relative to the total specimen weight. We tested Conventional Specimen (B1), Fiber- reinforced Specimen(B2), Specimen with steel slag (B3) & Fiber-reinforced concrete with steel slag (B4).

Keywords : Bituminous Concrete, Steel Slag, Aggregates, Lime Powder, Glass Fibre, Marshall Mix Design.
