<![CDATA[Advances in technology and science are anticipated to deal with the constraints associated with increasing the amount and quality of road construction, as well as road maintenance. Therefore, a construction technology for highway pavement layers that has been successfully developed in Germany since the 1960s, known as SMA S (Split Mastic Asphalt / Stone Matrix Asphalt with added Cellulose). This study was conducted with the aim of knowing the effect on the use of coconut fiber as a cellulose fiber additive in SMA (Split Mastic Asphalt / Stone Matrix Asphalt) type SMA mixtures. Determine the value of the Optimum Coconut Fiber Addition Rate and the value of the Marshall characteristics of the Stone Matrix Asphalt (SMA) mixture - Coarse using ex aggregate. Merak with varying levels of 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% The results of the research on the durability parameters of the Stone Matrix Asphalt (SMA) - Coarse mixture using the immersion test characteristic method for the Optimum Coconut Fiber Addition Level, the stability value decreases when it has been through immersion for 24 hours.]]>
