Pemanfaatan Limbah Baja (Slag Baja) Sebagai Bahan Campuran Aspal Terhadap Karakteristik Marshall

Abstract

Slag is non-metal solid waste that is produced from the metal melting process in the furnace and is a collection of oxides in a melt state and separated from the liquid metal phase during the melting process. This waste comes from the result of high kiln combustion residue produced by the steel smelting industry, which physically resembles an aggregate. Slag includes B3 waste (Toxic Hazardous Material). This steel waste is also one of the environmental problems so it is necessary to use or develop recycling technology for road pavement, one of the waste materials that will be tried to replace new aggregates in this research is steel slag which can be used as a filler from waste the steel industry is unfortunate if not utilized. Its use will also help reduce the waste in the environment. Asphalt Concrete (AC) is a type of flexible pavement that uses continuous aggregate gradation from coarse to fine grains. The strength of this mixture is in its aggregates which co-exist. The purpose of this study was to determine the effect of adding steel slag in the Laston AC-WC mixture on the physical properties of asphalt and Marshall parameters. In this research, steel slag is used as a filler in the Laston mixture, which passes through the No. filter. 200. The results of this study indicate that the addition of steel slag to the asphalt mixture can be used as a filler (filler). The stability value obtained from the addition of steel slag to the asphalt mixture for 0%, 20%, 40%, 60%, and 80% content has met the Marshall specifications with results of 1230,215 kg, 1164,295 kg, 980,234 kg, 1147, 173 kg and 1147,173 kg. For values of VIM, VFA, VMA, Flow, and MQ indicate quantities that meet specifications.
