520	3		_aStone Mastic Asphalt (SMA) is a gap graded hot mix asphalt that contains a large percentage of course aggregate and bitumen filler mastic. Usually, SMA mixes has been added with polymer modified binder. SMA is suffer with severe binder drain down due to the gap graded aggregates mixtures that tends to provide a stable stone to stone skeleton including a rich mixture of asphalt mastic. The Steel Fiber is the additive that will stabilize the asphalt mortar and thicken the bitumen to prevent excessive binder drain down. SMA is good to be used in the presence of fiber to enhance the durability of the SMA mixes. Thus, this paper is presenting the effectiveness of using steel fiber in improving the durability at the surface layer of SMA pavement, which are directly subjected to the traffic effects. To prepare SMA mixtures, Specimens were compacted by applying 50 blows on each face using a Marshall Impact compactor at specific compaction temperatures. Then, the modified specimens were tested to investigate the performance in terms of Los Angeles Abrasion Test, Marshall Stability Test, Resillient Modulus Test and Dynamic Creep. The results indicated that the specimens incorporating steel fiber can be used in binder course of flexible pavement because of its positive stability impact. The result shows that the addition of 0.3% fiber lead to better stability and stiffness while, 0.5% fiber for resilient and enhanced modulus dynamic creep at 25℃ and 0.4% fiber at 40℃. Thus, it can be concluded that the addition of steel fiber in the mixture has the potential to improve binder drain down problem. In order to generate a better pavement mixes in the future, it is advisable to have a further research using the fiber at different compacted temperature and different number of blows.
