ABSTRACT

The continuous development of artificial aggregates aims to address the limitations of natural aggregates. The increase in ceramic waste can have a negative impact on the environment. It is hoped that research using ceramic waste as an alternative aggregate can overcome the limitations of natural aggregates while reducing environmental pollution. This research focuses on assessing the volumetric and mechanical characteristics of Laston AC-BC mixtures, replacing natural fine aggregate with ceramic waste. Additionally, to determine the percentage of ceramic fine aggregates that meets the performance of the laston AC-BC mixture. Utilizing ceramic waste, 60/70 pen asphalt with 6% KAO, coarse aggregate, fine aggregate, and fly ash, the ceramic pieces are processed to meet standard particle sizes. The laston AC-BC mixture was designed with varying ceramic fine aggregate proportions of 0%, 25%, 50%, 75%, and 100%. Results indicate that ceramic fine aggregate effectively replaces natural fine aggregate up to a maximum of 55.45%, impacting VMA and VIM positively. Conversely, the voids filled with asphalt decrease as the percentage of ceramic fine aggregates used increases. The VIM value still meets Bina Marga requirements up to 55.45% use and the VFB value up to 60.6% ceramic fine aggregate. The Laston AC-BC mixture using fine ceramic aggregate can reduce the stability and flow value, although it still meets Bina Marga requirements but potentially reducing load-bearing capacity.
