Karakteristik Marshall pada Campuran Laston Asphalt Concrete-Wearing Course (AC-WC) dengan Pemanfaatan Limbah Keramik 

Marshall Characteristics of Laston Asphalt Concrete-Wearing Course (AC-WC) Mixture with Use of Ceramic Waste

Konstruksi jalan memerlukan agregat alam yang ketersediaanya semakin terbatas. Disisi lain, proses pembangunan konstruksi hunian dalam negeri menghasilkan limbah keramik yang melimpah. Namun pemanfaatan limbah keramik masih kurang sehingga dapat memicu pencemaran lingkungan. Perlu inovasi terbarukan terkait keterbatasan agregat alam dan melimpahnya sediaan limbah keramik. Penelitian mengenai pemanfaatan limbah keramik sebagai substitusi agregat halus pada campuran Laston Asphalt Concrete-Wearing Course (AC-WC) harapannya dapat menjadi langkah solutif. Tujuan penelitian ini difokuskan untuk mengetahui karakteristik Marshall beberapa variasi kadar keramik yang digunakan dan mengetahui kadar optimum penggunaan limbah keramik dalam campuran AC-WC. Penelitian ini menggunakan metode eksperiman berpedoman pada Spesifikasi Umum Bina Marga 2018. Pembuatan benda uji mewakili 5 kadar aspal rencana, sehingga didapatkan nilai Kadar Aspal Optimum (KAO) 5,7%. Selanjutnya, KAO 5,7 % divariasikan dengan kadar limbah keramik 30%, 35%, dan 40%. Diketahui dari hasil pengujian dan analisis Marshall kadar limbah keramik optimum yang dapat digunakan sebagai bahan substitusi yakni sebesar 30%. Dengan nilai stabilitas sebesar 823,06%, flow sebesar 2,5 mm, VIM 4,31%; VMA 15,06%; VFA 71,39%; Marshall Quotient (MQ) sebesar 333,67 Kg/mm; dan durabilitas sebesar 98,17%.

Road construction requires natural aggregates whose availability is increasingly limited. On the other hand, the domestic residential construction process produces an abundance of ceramic waste. However, the utilization of ceramic waste is still lacking so it can trigger environmental pollution. Renewable innovation is needed regarding the limitations of natural aggregates and the abundance of ceramic waste supplies. It is hoped that research regarding the use of ceramic waste as a substitute for fine aggregate in the Laston Asphalt Concrete-Wearing Course (AC-WC) mixture can be a solution. The aim of this research is focused on knowing the Marshall characteristics of several variations in the levels of ceramic used and finding out the optimum levels for using ceramic waste in the AC-WC mixture. This research uses an experimental method guided by the 2018 General Specifications for Bina Marga. It begins with making test objects representing the 5 planned asphalt grades so that KAO value is 5.7%. Furthermore, KAO 5.7% was varied with ceramic waste levels of 30%, 35% and 40%. It is known from the results of Marshall's testing and analysis that the optimum level of ceramic waste that can be used as a substitute material is 30%. With a stability value of 823.06%, flow of 2.5 mm, VIM of 4.31%; VMA of 15.06%; VFA of 71.39%; Marshall Quotient (MQ) of 333.67 Kg/mm; and durability of 98.17%.
