Abstract

Indonesia is one of the largest coal producers in the world. In 2019, based on Indonesia’s coal production, it reached 565.81 million tons with domestic consumption of 128.38 million tons. South Sumatra Province is one of the provinces that produces the largest coal production in Indonesia through one of the state-owned companies, namely PT. Bukit Asam Tbk. PLTUs by PT. Bukit Asam Tbk in South Sumatra Province can produce a lot of fly ash and bottom ash (FABA) waste in a day, 250 tons of bottom ash and 200–1000 tons of fly ash per day. Fly ash and bottom ash waste of PLTU Banjarsari and PLTU Tanjung Enim contains high pozzolan materials of total content SiO₂, Al₂O₃, Fe₂O₃ more than 70%. Flexible pavement is made in layers and consists of surface course, a subbase course, a base course, and a subgrade. This research focuses on flexible pavement on the surface course. Fly ash as a substitution for filler and bottom ash as a substitution for fine aggregate (sand), fly ash and bottom ash (FABA) replaced 100% of filler and sand material in this research, not as an additive. On this paper, only bring up physical, sieve analysis and chemical properties of fly ash and bottom ash (FABA) compared with cement as filler and river sand as fine aggregate in a standard flexible pavement. Aggregate inspection was conducted to determine whether fly ash and bottom ash used in this study met the requirements The General Specifications of Highways (Bina Marga) 2018 Revision 2, Ministry Public Work of Indonesia.
