Durabilitas Lapisan Asphalt Concretewearing Course (Ac-Wc) Dengan Menggunakan Filler Fly Ash Di Lingkungan Air Gambut
In the road pavement mixture, filler has a significant effect because it functions as a cavity filler. One filler that is commonly used is fly ash. Fly ash is a coal combustion waste that can be utilized and has a high silica content so as to improve the quality of the road pavement mixture. The purpose of this study was to determine the durability of the AC-WC layer using fly ash fillers in peat water environments. The proportion of fly ash used is 0%, 2%, 4%, 6% and 8%, each variation of fly ash is immersed for 0.5 hours, 24 hours, 48 hours, 72 hours, and 96 hours in peat water. The specifications used follow the 2018 Bina Marga standard using the Marshall method. The results of this study indicate the AC-WC mixture the longer the asphalt mixture is submerged in peat water, the lower the value of stability and durability of the mixture, the highest yield at 0.5 hours immersion is 1308.80 kg and the lowest at 96 hours immersion is 927, 42 kg. However, as the fly ash filler will increase the stability and durability value of the mixture, namely at 0% fly ash variation by 1160.18 kg and at 6% fly ash variation by 1308.80 kg. This is caused by fly ash being able to maintain stability and durability when submerged in peat water. The optimum variation of fly ash filler that can be added to the AC-WC mixture is 6% of the total weight of the aggregate. This value is based on a high stability value compared to other variations of 1308.80 kg. Then for the value of IKS able to withstand damage soaked for up to 48 hours, amounting to 90.07%.
