PEMANFAATAN LIMBAH KERAMIK SEBAGAI SUBSTITUSI AGREGAT HALUS UNTUK CAMPURAN PERKERASAN LAPIS ANTARA (ASPHALT CONCRETE-BINDER COURSE)

UTILIZATION OF CERAMIC WASTE AS A SUBSTITUTE FOR FINE AGGREGATE FOR INTERMEDIATE LAYER MIXTURES (ASPHALT CONCRETE – BINDER COURSE)

Perkembangan industri konstruksi mengalami kemajuan pesat seiring dengan pertumbuhan penduduk dan kebutuhan infrastruktur yang semakin meningkat. Meningkatnya produksi keramik sebagai bahan bangunan utama telah menyebabkan peningkatan pada limbah keramik yang dihasilkan. Pemanfaatan limbah keramik sebagai subtitusi agregat halus untuk campuran perkerasan lapis antara Asphalt Concrete-Binder Course (AC-BC) diharapkan bisa menjadi solusi. Penelitian ini mempunyai tujuan agar kadar optimum limbah keramik pada campuran AC-BC dapat diketahui sesuai dengan parameter marshall. Penelitian ini menggunakan metode eksperimentalberdasarkan spesifikasi Bina Marga 2018. Bahan yang digunakan berupa limbah keramik, aspal 60/70 dengan KAO 5,6%, agregat kasar dan halus serta flyash. Variasi 35%, 40%, dan 45% dari agregat halus keramik dipilih untuk campuran AC-BC. Dari hasil analisis, limbah keramik cocok digunakan sebagai bahan pengganti agregat halus dengan kadar paling optimum sebesar 35%. Bertambahnya penggunaan limbah keramik nilai VIM dan VMA naik, sedangkan VFA menurun namun masih memenuhi Spesifikasi Bina Marga 2018. Substtitusi agregat halus dengan 35% keramik menghasilkan nilai VIM 3,02%, nilai VMA 15,34%, VFA 80,35%, stabilitas sebesar 836,60 Kg, nilai flow atau kelelehan sebesar 2,7 mm, nilai Marshall Quotient 309,85 Kg/mm, dan nilai durabilitas sebesar 97,62%.

The development of the construction industry is progressing rapidly in line with population growth and increasing infrastructure needs. The increase in ceramic production as the main building material has led to an increase in ceramic waste produced. It is hoped that the use of ceramic waste as a substitute for fine aggregate for the Asphalt Concrete-Binder Course (AC-BC) pavement mixture can be a solution. This research aims to determine the optimum level of utilization of ceramic waste in the AC-BC mixture according to the Marshall parameters. This research uses an experimental method basedon the 2018 community development specifications. The materials used in this research were ceramics waste, asphalt 60/70 with KAO 5.6%, coarse and fine aggregates and fly ash. Variations of 35%, 40%, and 45% of fine ceramic aggregate were selected for the AC-BC mixture. From the analysis results, ceramic waste is suitable for use as a substitute for fine aggregate with the most optimum content of 35%. The increased use of ceramic waste increases the VIM and VMA values, while the VFA decreases but still meets the 2018 Bina Marga Specifications. Substitution of fine aggregate with 35% ceramic produces a VIM value of 3.02%, VMA value of 15.34%, VFA of 80.35%, stability of 836.60 Kg, flow or melting value of 2.7 mm, Marshall Quotient value of 309.85 Kg/mm, and a durability value of 97.62%.
