Analisis Parameter Marshall dan Indeks Kekuatan Sisa Pada Campuran Asphalt Concrete-Wearing Course Ditinjau Dari Penggunaan Filler PC, Abu Sekam Padi dan Abu Limbah Serbuk Kayu Kerajinan Kendang Jimbe Kota Blitar

Abstract

Road infrastructure is one of the important facilities in supporting community mobility. Therefore, alternative fillers with PC filler, rice husk ash, and wood powder waste ash from kendang jimbe crafts in Blitar City need to be sought. This research aims to describe the characteristics and IKS values in the AC-WC mixture as viewed from the Marshall parameter results. This research was conducted by testing using Marshall test equipment. Test results show that with increasing asphalt content, stability value tends to rise until the asphalt content reaches 6%, then decreases until the asphalt content reaches 7%. The flow value tends to rise with increasing asphalt content, the VIM value tends to decrease as the asphalt content increases, the VMA value of PC filler and wood powder waste ash tends to decrease with increasing asphalt content, whereas the VMA value of rice husk ash filler tends to increase. The VFA value tends to rise with increasing asphalt content. IKS value of PC filler and rice husk ash meets specifications. However, IKS value of wood powder waste ash filler does not meet specifications.
