Researches demonstrate that fibers boost performance of concrete incredibly. It’s determined that in literature steel fibers increase flexural strength and energy absorption capacity of the cementitious composites. However concrete highways consist of steel fibers in corrosive conditions eliminate fiber’s effect. Therefore producers of polymeric fibers launch fibers which can withstand corrosive environments and chemicals, and launch polyester and polypropylene fibers alternative to steel fibers. This research intends to determine the performance of concretes consist of polyester fiber, polypropylene fiber and steel fiber against traditional concrete. For this reason, fresh and hardened concrete properties of the concrete mixtures produced with 0%, 1% and 2% are determined by laboratory tests. The mechanical behaviors of these concrete specimens are investigated by compressive strength and tensile strength tests on 150x150x150 mm cubic and 100x100x500 mm prismatic specimens respectively. The abrasion resistance of the pavement concrete is measured by Bohme abrasion test on 70x70x70 mm cubic specimens. Test results showed that fibers are reinforced concrete against external effects which can be occurred during the service life of the rigid pavements. Significant developments are determined with the polymer fiber additives on concrete abrasion resistance and mechanical behavior of concrete.
