Characteristic of Asphalt Mixture using Fly Ash and Bottom Ash Substitution in Reducing Environment Pollution

Abstract One of the waste materials produced by industry activities is fly ash and bottom (FABA), it brick combustion waste. Fly hazardous toxic (B3) for contains heavy metal oxides polluting environment. Related to condition, output study toxicity potential test carried out coal in Nagan Raya PLTU (Electric Steam Power Plant) proving conversely. The relatively safe be used as construction material. explained that have adequate good potency utilized. potencies developed utilization asphalt mixture material including fine aggregate substitution filler substitution. research aimed find characteristic utilizing FABA road pavement concrete layer (AC-WC) reduce environment pollution detect appropriate proportion optimal utilization. percentage must meet requirement binder 5-15% weight, while minimum 75% weight filter pass No. 200 (0.075 mm). both mixtures using ashin 15%-30% variation was different. similar. Both concluded optimum level 5% 30% : 70% specification, subtitution Portland cement resulting all parameters specification required Bina Marga 2018.
