PENGARUH PENGGUNAAN ABU SEKAM PADI SEBAGAI BAHAN PENGGANTI ABU BATU DALAM CAMPURAN ASPHALT CONCRETE – WEARING COURSE (AC-WC) TERHADAP PARAMETER MARSHALL

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