Abstract

This study investigates the effect of using glass powder as a filler in Asphalt Concrete – Wearing Course (AC-WC) mixtures on the mechanical properties of the pavement. The research aims to evaluate the impact of varying glass powder contents (0%, 25%, 50%, 75%, and 100%) as a substitute for mineral filler on parameters such as stability, flow, Marshall Quotient (MQ), voids in mineral aggregate (VMA), voids in the mixture (VIM), and voids filled with asphalt (VFA). The experimental method involves material testing, mixture design, and Marshall testing in accordance with Indonesian National Standards (SNI). The results show that the addition of glass powder filler significantly influences the mixture’s performance. Increasing the glass powder content tends to raise the flow value, affect the MQ value, and modify the volumetric characteristics of the asphalt mixture. The optimal filler substitution level was achieved at a certain percentage that met the specification requirements for AC-WC mixtures. This finding suggests that glass powder, as a recycled material, has the potential to improve the sustainability of road construction while maintaining structural performance.
