Abstract

Jalan raya memiliki peran krusial dalam mobilitas dan pertumbuhan ekonomi di Indonesia. Namun, banyak ruas jalan mengalami kerusakan parah, sebagaimana tercatat dalam Statistik Transportasi Darat 2021 oleh BPS. Untuk meningkatkan kualitas dan keberlanjutan jalan, solusi ramah lingkungan seperti pemanfaatan limbah industri menjadi fokus utama. Salah satunya adalah pemanfaatan fly ash, limbah hasil pembakaran batu bara, sebagai filler dalam campuran aspal beton (AC), khususnya perkerasan lentur. Indonesia sebagai negara dengan cadangan batu bara besar menghasilkan sekitar 4,1 juta ton limbah padat setiap tahun. Peraturan Pemerintah Nomor 22 Tahun 2021 menetapkan bahwa limbah FABA (fly ash dan bottom ash) tidak lagi dikategorikan sebagai limbah B3, sehingga membuka peluang pemanfaatan yang lebih luas, termasuk sebagai pengganti semen dan bahan campuran jalan. Penelitian ini menggunakan fly ash sebagai substitusi filler dalam campuran aspal laston AC-BC untuk mengevaluasi pengaruhnya terhadap performa campuran berdasarkan parameter Marshall. Variasi kadar fly ash yang digunakan adalah 20%, 40%, 60%, 80%, dan 100% dari total filler. Komposisi campuran dirancang menggunakan metode trial and error dan menghasilkan kadar aspal optimum sebesar 6,35% yang memenuhi standar Bina Marga 2018 Revisi 2. Hasil penelitian menunjukkan bahwa variasi 100% fly ash memberikan performa terbaik dengan nilai stabilitas 937,365 kg dan Marshall Quotient 276,494 kg/mm. Peningkatan ini diduga berasal dari distribusi filler yang lebih homogen serta potensi reaksi pozzolanik fly ash yang meningkatkan kekakuan dan daya ikat campuran.

Roads play a crucial role in mobility and economic growth in Indonesia. However, many road sections suffer severe damage, as recorded in the 2021 Land Transportation Statistics by BPS. To improve road quality and sustainability, environmentally friendly solutions such as the use of industrial waste are becoming a key focus. One such solution is the utilization of fly ash, a byproduct of coal combustion, as a filler in asphalt concrete (AC) mixtures, particularly for flexible pavement structures. Indonesia, with its large coal reserves, produces approximately 4.1 million tons of solid waste annually. Government Regulation No. 22 of 2021 reclassified FABA (fly ash and bottom ash) from hazardous waste (B3) to non-hazardous, thereby opening up broader opportunities for its use, including as a substitute for cement and as a component in road pavement mixtures. This study uses fly ash as a filler substitute in AC-BC (Asphalt Concrete – Binder Course) mixtures to evaluate its effect on asphalt performance based on Marshall parameters. The fly ash content variations tested were 20%, 40%, 60%, 80%, and 100% of the total filler weight. The mixture composition was designed using a trial-and-error method, resulting in an optimum asphalt content of 6.35%, which meets the 2018 Bina Marga Specification Revision 2. The research findings indicate that the 100% fly ash variation delivered the best performance, with a stability value of 937.365 kg and a Marshall Quotient of 276.494 kg/mm. This improvement is believed to result from better filler distribution and the pozzolanic reaction potential of fly ash, which enhances the stiffness and binding capacity of the asphalt mixture.
