Reinforcement consists of including certain materials with some desired properties within other material which lack those properties; the concept of using fibres to improve the behaviour of materials is old. The modern developments of fibre reinforcement started in the early 1960s. A multitude of fibers and fiber materials were introduced and are continuously being introduced in the market. Stone Mastic Asphalt pavement surfaces have been used successfully in Germany on heavily trafficked roads. In recognition of its excellent performance a national standard was set in Germany in 1984. Since then SMA has spread and gained some acceptance all over the world, because of its excellent performance characteristic the use of SMA increased in popularity amongst road authorities and asphalt industry. The present paper investigates on the characteristics and properties of glass fiber reinforced Stone Mastic Asphalt, which may have the benefit of improving the performance of road pavement. The use of Glass fiber showed a varied results, it was found the addition of fiber does affect the properties of bituminous mixes as well as that the amount of fiber content in the mix, by decreasing it's stability and increasing the voids between the aggregates, also an increase in the flow value followed by a decrease when the fiber content increase above the 0.20%, while the stiffness of the mixes decreases as compared to the original mix.
