ABSTRACT
Split Mastic Asphalt (SMA) as a solution to reduce the problem of damage to the road pavement layers before the end of it’s service period due to high traffic loads. Cellulose fiber is needed as an asphalt stabilizer. The study was conducted with a pure experimental method to determine the effect of cellulose fiber on the marshall performance of Split Mastic Asphalt Mixtures (SMA). This study used a mixture of SMA by using five variations of the addition of natural cellulose fibers from corn cobs that is 0.15%; 0.30%; 0.45%; 0.6%; 0.75%. The results showed that the corn cob cellulose fiber determines the characteristics of Marshall namely weakness, flow, VIM, VMA,. But not all levels of varieties meet specifications. For optimum levels of cellulose fiber added to the SMA mixture, the levels of 0.15% to 0.3% were chosen, because in that scale the increase in strength performance was supported by all other characteristics that passed the 2018 Bina Marga specifications.
