Studi Eksperimental Warm Mix Asphalt (Wma) Dengan Bahan Tambah Zeolit Terhadap Gradasi Campuran Laston Dan Lataston

---

ABSTRACT
Asphalt mixtures in Indonesia consist of three types, Asphalt Concrete (AC), Hot Rolled Sheet (HRS), and Stone Matrix Asphalt (SMA). The main difference among these mixtures lies in the aggregate gradation. Generally, asphalt roads are constructed using Hot Mix Asphalt (HMA), which produces relatively high CO₂ emissions during the heating process, contributing to ozone layer depletion and global warming. A solution to reduce the environmental impact of HMA is to lower the mixing temperature, resulting in Warm Mix Asphalt (WMA). WMA requires additives to reduce the mixing temperature, one of which is zeolite. This research focuses on Asphalt Concrete (dense graded) and Hot Rolled Sheet (gap graded) to determine which gradation type is more suitable for zeolite addition by conducting Marshall and aging tests. The results showed that WMA has a higher Optimum Asphalt Content (OAC) than its HMA counterpart, for both Laston and Lataston mixtures. The density of the WMA mixture is lower than that of the HMA mixture. The stability of the WMA mixture is also lower compared to HMA, which aligns with its volumetric characteristics where the Voids in the Mix (VIM) and Voids in Mineral Aggregate (VMA) of the WMA are higher. This indicates that WMA contains more air voids than HMA, resulting in a lower Voids Filled with Asphalt (VFA) value. Aging test results show that WMA experiences slower aging compared to HMA during its service life (long-term aging). All test results indicate that zeolite is effective in both types of gradation, as they meet the specifications set by Bina Marga Revision 2 of 2020. However, zeolite performs more effectively in the Lataston mixture (gap-graded), which has a longer aging resistance. Keywords: Aggregate Gradation, Warm Mix Asphalt, Zeolite, Marshall, Aging
