Several studies have investigated the recovery of asphalt mixtures during fatigue life; however, there is still an inadequacy of determining fatigue failure and recovery of Stone Matrix Asphalt (SMA) mixtures under repeated loading. This paper presents the results of a laboratory study which was aimed to compare the effect of cellulose fiber with SBS modifier on the fatigue failure and recovery of SMA. Three different mixtures (containing cellulose fiber, 3% SBS, and 5% SBS) were fabricated by two types of aging conditions. In addition to fatigue failure and recovery of the SMA, resilient modulus, indirect tensile strength and long-term oxidative aging of this mixture were investigated. The results indicated that using the SBS modifier enhanced indirect tensile strength, resilient modulus, resistance to fatigue failure, and recovery of the mixture. Considering aged mixtures, although the long-term aged mixtures had higher failure life, resilient modulus and indirect tensile strength, they had lower recovery potential. Also, while using SBS modifier had a positive effect on reducing the impact of aging on the indirect tensile strength and the resilient modulus, it could not reduce the detrimental impact of aging on the recovery potential of the mixtures.
