The purpose of this research is to know the effect of beach sand as a substitute for river sand in a mixture of concrete asphalt against the characteristic values of the marshall and to determine the effect of adding sugarcane ash filler with the percentage of ash filler 0%, 5%, 10%, 15% on the concrete asphalt mixture against the characteristic values of the marshall. This research is an experimental study using fillers in the form of sugarcane ash filler with varying levels of variation in the amount of 0%, 5%, 10%, 15%. The specimens using AC-BC mixture was then tested using the Marshall method values of stability, density, flow, VIM, VMA, VFA, MQ. The results of this study indicate that the addition of sugarcane ash filler and the use of beach sand as a substitute for river sand affect the value of the characteristics of the marshall. The more filler levels used in the asphalt mixture, the greater the value of stability and MQ. While the flow value, density, VIM, VMA, VFA are getting smaller. Other factors that influence marshall characteristic values are asphalt content used, aggregate gradation, temperature in compaction, mix quality, and the process of mixing asphalt.
