Abstract

Asphalt Concrete Wearing Coarse (AC-WC) consists of asphalt and aggregate mixed, that largest composition is aggregate (90% from the total weight of mixture). The availability of mixed-forming materials is very important in ensuring smooth implementation in the field, apart from the quality of the material. In some areas, the availability of filler is considered quite difficult because the filler usually comes from rock ash, so it takes a replacement material that has the same specifications as the filler from rock ash. The possible material is fly ash which is waste in coal mines and has not been utilized to the fullest. This research will analyze the performance of AC-WC coarse that make use of filler substitution material using fly ash with variation FA-0%, FA-5%, and FA-10%. The samples made by Marshall Method will give the Optimum Asphalt Content (OAC) value on each mix variation. While the performance of these AC-WC mixtures on secondary compaction by traffic was carried out using the Percentage Refusal Density (PRD) Method. The analysis result shows that the OAC value at 0% fly ash variation is 5.95%, at 5% fly ash variation is 6.25%, and at 10% fly ash variation is 6.32%. While the performance of AC-WC mixture indicated by the PRD value meets the specifications, namely the PRD test gives a minimum VIM value of 2%. Based on the results of the study, it can be seen that with the addition of fly ash there is an increase in the asphalt content used but the increasing is not too big. So the fly ash can recomended to use as substitution filler on AC-WC mixture.
