Stone Matrix Asphalt Performance with Glycerin Pitch as Asphalt Binder Extender

This research aims to utilize glycerin pitch waste as an alternative asphalt binder (extender) in Stone Mastic Asphalt (SMA) mixture. Glycerin (GP) is a by-product from crude glycerol refining process the palm oil oleochemical industry. The method was carried out by testing chemical and physical characteristics of GP comparing it pen 60/70, then based on rheology concrete characteristics. ANOVA statistical test Tukey-Kramer grouping were used know significant use SMA variations content tested 60/70 0%, 15% 25% weight, for mixture which under (Pb) conditions Marshall characteristic, immersion index drain down. results show that has potential extender, with maximum 22% weight or ratio 1 GP: 4 60/70. using Pb = 7% produce meets specification. Statistically, stability SMA, effect + In index, all type mixture, while draindown SMA+0%
