Stone Mastic Asphalt (SMA) is a gap-graded asphalt mixture that depends on the stone-to-stone contact to provide its load-carrying capacity against rutting and stripping. Even though SMA has good performance, especially in resisting permanent deformation, it suffers from excessive binder drain down due to high bitumen content. Thus, the aim of this study is intended to utilize bamboo fiber to control the drainage and bleeding problem. In this study, bamboo fiber is chosen as a modified binder to enhance the performance of stone mastic (SMA 20) due to more economical than other conventional fibers. The aim of this study to evaluate the mechanical performance of bamboo fiber stone mastic asphalt (SMA) in terms of Marshall stability, resilient modulus, dynamic creep, and Cantabro Loss. Twelve samples of SMA 20 mix with PEN 60/70 binders are tested for each test. Bamboo fiber in the range of 0%, 0.2%, 0.3%, 0.4%, 0.5% and 0.6% of on the aggregate weight used in the original mix design. From the results, it shows that the addition of 0.4% fiber contributes to the lowest value of abrasion and dynamic creep and 0.4% producing the highest value for resilient modulus, stability, density, and stiffness. Based on that,0.4 % is the optimum fiber content that could be used to design. Thus, it can be concluded that the existence of fiber is capable of enhancing the performance of SMA 20.
