Glass may be utilized in a wide variety of contexts; nevertheless, as its use expands, so does the amount of trash that is generated annually from broken glass. Reusing or recycling these products is the most productive course of action that may be taken. This study's objective is to determine how well a flexible bituminous pavement functions after having broken glass shards added to it as aggregate material. Crushed glass was added to the mixture at percentages of 5%, 10%, and 15% by weight. An equivalent amount of glass particles replaced fine aggregate in order to meet the target. As the proportion of glass in the mixture increased, the optimal binder composition of the mixture dropped. Both the flow values and the stability values rose rapidly as the fraction of shattered glass increased; however, the stability values decreased as the glass content reached 15%. According to the findings of the research that was conducted, substituting crushed glass for fine aggregates might potentially increase the stability and flow value of the design mix by up to 10%. The structural qualities of the mix would improve, and the amount of crushed waste glass produced would decrease. This partial replacement for fine total would without a doubt improve the longevity of the adaptable bituminous asphalt, and as an added perk, the amount of time spent unloading crushed waste glass would be decreased by half.
