Abstract
Roads are one of the important infrastructures in community daily activities. With the increasing need for road construction, the need for natural materials also increases. So, there is a need for innovative replacement materials that are efficient, economical, easily accessible, and environmentally friendly. Indonesia is one of the countries producing the most nickel slag waste in the world, reaching 72 million tons or 52% of the world's total reserves. Nickel slag has a high silica content and physical properties that are almost the same as natural aggregates. The Toxicity Characteristic Leaching Procedure (TCPL) carried out on nickel slag also shows that nickel slag is included in the non-hazardous waste category, indicating that nickel slag has the potential to be an alternative to meet the needs for construction materials and road pavement. This research aims to determine the optimum content of nickel slag as a substitute for natural aggregate in Asphalt Concrete Binder Coarse (AC-BC) as well as the effect of variations in nickel slag aggregate content of 0%, 20% and 60% on the resilience modulus characteristics. The resilience modulus test in this study aims to consider the tensile characteristics of asphalt concrete mixtures. The results of this research show that the optimum nickel slag content is based on the resilience modulus value, namely 60% slag content with an optimum asphalt content of 5.5% giving a resilience modulus result of 3453.67 Mpa. The use of nickel slag in intermediate layer asphalt concrete (AC-BC) mixtures as a substitute for natural aggregate is highly recommended, because it can increase the resilience modulus value. This happens because the addition of voids in the mixture makes the asphalt effectively fill more voids, so that indirectly the durability of the mixture increases. Keywords: Nickel Slag, Resilient Modulus, Asphalt Concrete.

| Additional Information: | Jalan merupakan salah satu prasarana penting dalam kegiatan dan aktivitas sehari-hari masyarakat. Dengan meningkatnya kebutuhan pembangunan jalan, semakin meningkat juga kebutuhan material alamnya. Sehingga dibutuhkannya inovasi bahan pengganti yang efisien, ekonomis, mudah dijangkau, dan ramah lingkungan. Indonesia menjadi salah satu negara penghasil limbah slag nikel terbanyak di dunia yang mencapai 72 juta ton atau 52% dari total cadangan dunia. Slag nikel memiliki kandungan Silika yang cukup tinggi dan sifat fisik yang hampir sama seperti agregat alam. Toxicity Characteristic Leaching Procedure (TCPL) yang dilakukan pada slag nikel juga menunjukan bahwa slag nikel masuk ke dalam kategori limbah yang tidak berbahaya. Sehingga slag nikel berpotensi menjadi alternatif untuk memenuhi kebutuhan bahan konstruksi dan perkerasan jalan. Penelitian ini bertujuan untuk mengetahui kadar optimum slag nikel sebagai pengganti agregat alam dalam campuran beraspal lapis antara (AC-BC) serta pengaruh variasi kadar agregat slag nikel 0%, 20% dan 60% terhadap karakteristik modulus resillien. Pengujian modulus resilien pada penelitian ini bertujuan untuk memperhitungkan karakteristik tarik campuran aspal beton. Hasil dari penelitian ini menunjukkan kadar slag nikel optimum berdasarkan nilai modulus resilien yaitu pada kadar slag 60% dengan kadar aspal optimum 5,5 % memberikan hasil modulus resilien 3453,67 Mpa. Penggunaan slag nikel pada campuran aspal beton lapis antara (AC-BC) sebagai pengganti agregat alam sangat disarankan, karena dapat menambah nilai modulus resiliennya. Hal itu terjadi karena penambahan rongga dalam campuran yang membuat aspal efektif mengisi rongga lebih banyak, sehingga secara tidak langsung keawetan campuran meningkat. | |||||||||
