Abstract
Using of fibers is not a new phenomenon; the technique of fiber-reinforced bitumen began as early as 1950. Fiber reinforcement refers to incorporating materials with desired properties within some other materials lacking those properties [1]. The principal function of the fiber is to provide additional tensile strength in the resulting composite. This could increase the amount of strain absorbed during the fatigue and fracture process of the mixture [2]. Fibers are sometimes added to stabilize the binder during mixing and placement. An additional benefit of using fibers is that fibers have been shown to allow increased asphalt binder contents and thus increase film thicknesses thereby increasing durability [5]. Asphalt cement modifiers have been used in pavement technology to enhance pavement performance and reduce different types of pavement distress, of which, rutting, low temperature cracking, fatigue cracking, stripping, and hardening are the most common failure. The present project investigate the usability of mineral fibers in order to resist the stresses occurring at the surface layer of pavement, which are directly subjected to the traffic effects. For this purpose four different types of mineral fibers (steel , aluminium , copper and tin), four different fiber rates (1% , 1.5% , 2% , 2.5% ) by total weight of mixture, with varying lengths of mineral fiber (0.5 ,1.0 ,1.5 ,2.0) cm, and four different thickness (0.2 , 0.4 , 0.7 , 0.9 ) mm were used in this study. All specimens have been tested by Marshall method. The results indicated that adding (1.5%) of the copper fiber by the total weight of mixture, with (0.5 cm) length and (0.4 mm) thickness increase Marshall stability by (34%) as compared with the conventional mix.
