Abstract

Abstract This research aims to utilize molasses waste as a partial replacement material for asphalt in AC-BC asphalt mixtures. Molasses is the final product of making sugar, which is brown in color and in the form of a thick liquid. The research method used was to test the properties and characteristics of molasses, then compare them with the properties and characteristics of Pen 60/70 asphalt. Next, tests were carried out based on the rheological properties of asphalt and the characteristics of AC-BC asphalt concrete. Variations in the levels of molasses mixed with Pen 60/70 asphalt are 0%, 5%, 10%, and 15% of the asphalt weight. Then the mixture of molasses and asphalt is used as a binder for the AC-BC asphalt mixture. Marshall Testing and Immersion Index were carried out on this asphalt mixture. This study shows that molasses has the potential to be used as a partial replacement material for asphalt in AC-BC asphalt mixtures, which still meet the Bina Marga Specifications. Keywords: molasses waste; asphalt; asphalt mix; Marshall Testing; Immersion Index Abstrak Penelitian ini bertujuan untuk memanfaatkan limbah molase sebagai bahan pengganti sebagian aspal pada campuran beraspal AC-BC. Molase merupakan produk akhir pembuatan gula, yang berwarna cokelat dan berbentuk cairan kental. Metode penelitian yang dilakukan adalah dengan menguji sifat dan karakteristik molase, lalu membandingkannya dengan sifat dan karakteristik aspal Pen 60/70. Selanjutnya dilakukan pengujian berdasarkan sifat reologi aspal dan karakteristik beton aspal AC-BC. Variasi kadar molase yang dicampurkan pada aspal Pen 60/70 adalah 0%, 5%, 10%, dan 15% terhadap berat aspal. Kemudian campuran molase dan aspal tersebut digunakan sebagai bahan pengikat campuran beraspal AC-BC. Terhadap campuran beraspal ini dilakukan Pengujian Marshall dan Indeks Perendaman. Studi ini menunjukkan bahwa molase berpotensi untuk digunakan sebagai bahan pengganti sebagian aspal pada campuran beraspal AC-BC, yang masih memenuhi Spesifikasi Bina Marga. Kata-kata kunci: limbah molase; aspal; campuran beraspal; Pengujian Marshall; Indeks Perendaman

Abstract

Asphalt aging is one of the causes of quality deterioration in flexible pavement. Previous studies have shown that molasses can be used as a substitute for asphalt. This study uses molasses at 15% of the asphalt weight. Aging tests were conducted on AC-BC asphalt mixtures, which are intermediate layers often used in areas with high deformations. Asphalt aging occurs in both short and long terms. Short-term aging occurs during mixing, tested using Short-Term Oven Aging (STOA), while long-term aging occurs during service life, tested using Long-Term Oven Aging (LTOA). STOA testing involves heating the loose mixture in a laboratory oven for 4 hours at 135°C, while LTOA involves heating solid specimens in a laboratory oven for 2 days and 5 days at 85°C. The test results indicate that aging affects the characteristics of asphalt mixtures, as evidenced by an increase in Void in Mixture (VIM) and Void in Mineral Aggregate (VMA) values, while stability, flow, Void Filled with Bitumen (VFB), and density values tend to decrease. The test results also show that HMA AC-BC +15% Molasses is better at maintaining stability values, as evidenced by the higher stability value of HMA AC-BC + 15% Molasses compared to HMA AC-BC Control.
