Abstracts: Stone Matrix Asphalt (SMA) is gap graded mixture which contains the higher content of the coarse aggregate, asphalt as binder and fibers as the stabilizers. In the present study, we have referred different literature and concluded the Optimum Fiber Content at 0.3% which increase the stability and decrease the flow value. The fiber content will be added with the binder namely bitumen grade of 60/70 in SMA. We have performed the tests and obtained the physical properties of the conventional bitumen and aggregate. We have studied Marshall Test and observed that 0.3% addition of coconut fiber and 0.3% addition of jute fiber with the 6% of bitumen content significantly improve the Marshall property of Stone Matrix Asphalt.
