Permanent Deformation Characterization of Stone Matrix Asphalt Reinforced by Different Types of Fibers

This paper focused on the stone matrix asphalt (SMA) technology that was developed essentially to guard against rutting distress. For this procedure, fibers play a racy role in stabilizing and preventing drain down problem caused by necessity of high binder content coupled with their strengthening effect. A set specimens cylindrical slab shapes were fabricated inclusions jute, polyester, carbon fibers. each type, three contents 0.25%, 0.5%, 0.75% weight mixture added lengths 5, 7.5, 10 mm. The prepared mixtures tested gain essential pertained parameters discriminated values down, Marshall quotient, rut depth, dynamic stability. It has appeared rate 0.5% 7.5 mm length is much appropriate yield best performance modified mixtures. At these values, recorded highest increase level resistance stability 53% 100%, respectively while, jute exhibited lowest improvement only 34% 63%, respectively; nevertheless, they produced having value. Regarding index plastic stiffness, polyester embedded occupied first rank increasing 38%.
