Whenever it comes to road pavements, asphalt and its mixture are used to improve the performance and durability of the surface. SMA Mix (also known as Stone mastic asphalt or Stone matrix asphalt) is a great alternative to bituminous concrete or thick graded mix for this application because of its durability (DGM). Countries in Europe and North America were the primary users of this term. Stone Mix is an asphalt blend that has been gap-graded. Different materials (natural or manufactured) are employed as stabilisers, and Stone or Slag is utilised as coarse aggregate to make high-bituminous material with a high degree of bituminous content. In this study, a variety of alternate methods for improvement are explored, including the use of waste materials as fillers, such as coconut shell charcoal powder, glass powder, and bagasse fibre, to lower costs while simultaneously improving roadway quality and safety. The primary goal of the study is to compare the outcomes obtained with these fillers to the results obtained with the conventional mix, which is the baseline. Crushers and pavement fillers must have certain qualities to function properly. These features include crushing, surface moisture, grading, and freezing.
