The goal of this paper is to study the feasibility of partial and total substitution of Limestone (LS) filler by Barite powder (BP) in Stone matrix asphalt (SMA) mixtures. To evaluate barite powder performance, resilient modulus, indirect tensile strength, freeze-thaw cycles, dynamic creep at two different temperatures, and bitumen draindown tests were used. The obtained values revealed that an increase in barite powder content from 50% to 100% improved the Stone matrix asphalt mixture moisture performance by 4.5% after going through 5 freeze-thaw cycles while on the other hand, it had an 18.5% reverse effect on the permanent deformation in higher temperatures. Also, despite barite powder's positive effect on bitumen draindown compared to the control samples; it could not thoroughly control SMA bitumen draindown.
