Asphalt Concrete Wearing Course (AC-WC) is the topmost layer or also known as the wear layer on the pavement which must be designed to be water-resistant, weather-resistant, and strong enough to withstand the weight of the vehicle's wheels. The AC-WC mixture consists of constituent materials, namely coarse aggregate, fine aggregate and filler. In this study, rice husk ash was used as a substitute for stone dust in the AC-WC mixture with variations in the rice husk ash mixture, namely 5%, 10%, 15%, 50%, 75% and 100%. This study aims to determine how much influence and comparison of the use of rice husk ash as a substitute for stone dust in the mixture (AC-WC) on Marshall parameters. The test was carried out with guidelines on the 2018 bina marga specification. From the results of tests carried out in the laboratory, the values of the marshall parameters were obtained, namely: rice husk ash could not increase the flow value, the stability value and the marshall quotient (MQ) increased with the use of rice husk ash in variation of 5%, the variation of 10% and 15% can not meet the VIM value. Variations 50%, 75% and 100% can not be tested marshall.
