Penggunaan Limbah Slag Nikel Untuk Material Jalan Ramah Lingkungan

The recycling and use of waste is one of the quiet important issues associated with the construction of environmentally friendly and sustainable roads today. The use of natural aggregates as materials for road infrastructure reduces availability, necessitating the need for alternative materials, one of which is nickel slag. The increase in nickel production is directly proportional to the increase in nickel slag production as a byproduct of nickel processing. The purpose of this research was to assess and control the performance of asphalt mixtures containing nickel slag in the Intermediate Laston (AC-BC) pavement layer. The physical properties of the materials used, namely asphalt, aggregate, and nickel slag, were tested, and for the chemical and mineral properties of nickel slag, X-ray fluorescence spectrometry (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope well as the results of testing the physical properties of nickel slag meet the requirements used in road construction materials. As a result, nickel slag is a viable alternative for environmentally friendly road construction materials.
