It is well established that aggregate shape characteristics affect bitumen pavement performance. The strength and frictional characteristics of the aggregate structure are controlled by angularity and texture. While aggregate form affects the anisotropic response of Bitumen mixtures, aggregate texture has a significant impact on the adhesive bond between the aggregate and the binder. One important shape criterion that influences how well aggregate performs and behaves in bituminous mixes is the flakiness index. The physical characteristics of aggregates have a significant impact on the strength and serviceability requirements of bituminous mixtures, such as Stability, Flow, and voids in total mix and Voids Filled with Bitumen (VFB). It was discovered that the internal resistance of a bituminous mix correlates well with the change in rotation angle of coarse aggregate. The internal resistance of a mix was also influenced by the particle shape, which also impacted how densely aggregate was packed. For boosting aggregate internal friction and enhancing rutting resistance, cubical particles were preferred. The physical characteristics of bitumen and aggregates were identified in the current investigation. For DBM Grade-II with varying percentages of combined flakiness and elongation, the Marshall characteristics were obtained using the Rothfutch's approach. The study's findings revealed that as the combined Flakiness and Elongation index increases, the strength and stability of bituminous mixes steadily decline. For greater strength, bituminous mixes should not exceed 30% on the Flakiness and Elongation index
