The effect of fish scale waste on the performance properties of asphalt concrete

Owing to the increasing population andrapidly developing urbanization processes, production is on the rise. The output generated leads to waste. These wastes contribute to pollution, and collection areas are gradually diminishing. Reducing environmental impacts and embracing sustainability principles are progressively gaining significance. Within this framework, the recycling and reuse of industrial waste are crucial for the advancement of environmentally friendly construction materials. As global sustainability and environmental awareness intensify, the reintegration and recycling of industrial waste have emerged as a significant area of research in the construction materials sector. In this context, the application of alternative additives derived from natural and renewable resources, rather than conventional ones, in asphalt concrete production holds the potential to mitigate environmental repercussions. The primary objective of this study is to evaluate the effect of fish scales, an industrial waste material from the fish processing industry, on the performance characteristics of asphalt concrete. Fish scales are showing promise as a potential alternative additive in the manufacturing of bituminous mixtures. In this study, asphalt concrete incorporating fish scale additives at various concentrations (3%, 5%, and 7%) was produced, and the mechanical properties and durability parameters of these mixtures were experimentally investigated. The findings from this experimental study underscore the potential to encourage the utilization of alternative additives to lessen environmental impact and enhance waste management within the construction sector. Furthermore, the data acquired will serve as a foundation for future investigations and contribute to the creation of novel applications that promote the use of industrial wastes like fish scales in the production of sustainable construction materials. The experiments showed that using 3% fish scale waste in asphalt concrete is suitable. This allows for resource efficiency and contributes to environmental sustainability through the reuse of waste.
