Pengaruh Pemanfaatan Pelepah Abu Pisang Sebagai Filter Lapisan Aspal AC-WC Terhadap Nilai Marshall

Abstract

The increasing development demands additional infrastructure, including road facilities. Banana ash fronds are natural polymers that can be used as an alternative filler in asphalt. The consideration of using banana ash stalk is because it is easy to obtain and can reduce banana frond waste and become a useful material. This study aims to analyze: 1) How is the effect of adding banana ash filler content to the AC-WC asphalt. 2) To find out the results of the stability of the asphalt using the Marshall Test and the value of KA0 (Optimum Asphalt Content) from the use of banana ash midribs. This study used an experimental method which was carried out in the laboratory with a variation of the asphalt content plan 4.5%; 5%; 5.5%; 6%; 6.5%; 7%. Three samples were used for each variation of the asphalt content of the plan. From the AC-WC asphalt mixture with filler 2% has a stability value of 1051 kg and filler 4% of 1022 kg. And in obtaining Optimum Asphalt Levels of 6.10% for filler levels 4% and 6.04% at 2% filler levels, the values of Density, Stability, Flow and MQ increased greater in 2% filler mixtures and 4% filler content mixtures there was a decrease. So it can be concluded that the greater the addition of banana ash filler, the Stability value will decrease and vice versa the Flow value will increase.
