Stone Matrix Asphalt (SMA) is a breach separated bitumen combination. It is essential for the mixture that the coarse aggregates have direct stone-on-stone contact with each other. This is one of the requirements for the mixture. In the present investigation, SMA mixes with two different aggregate gradations and two different nominal maximum aggregate sizes, 16mm and 13.2mm, were created. These mixtures were given the designations SMA 1 and SMA 2, respectively. Three different types of fibers, including pelletized Cellulose Fiber (CF), Coconut Coir (CC), and Sisal Fiber (SF), and Shredded Waste Plastics (SWP) were used in mixtures with VG 30 bitumen to control drain down According to the findings of the drain down test, the amount of fiber that could be included in the mixture was capped at 0.3% by weight, while the percentage of SWP that may be included was between 4% and 16% by weight of bitumen. When case SWP combinations were tested, it was found that 8 and 12% plastic percentage generated the best results. The SMA 1 gradation exhibited superior outcomes than the SMA 2 gradation for all sorts of mixtures, with the exception of moisture susceptibility, where both gradations performed virtually identically.
