Abstract

Roads need to possess the proper combination of thickness and design to safeguard the subgrade from damage and to support the load pressure on the road. This study investigates the impact of incorporating fly ash and plastic granules on the performance of asphalt mixtures (AC-WC) for sustainable road construction. The experimental design involved setting the asphalt content according to standard specifications while maintaining a constant fly ash content of 6%. Performance evaluation was conducted using the Marshall test to assess key parameters such as stability, flow, and Marshall Quotient (MQ), which reflect the mixture's strength and flexibility. The results indicated that at a plastic granule content of 6%, the values for Voids in Mixture (VIM), Voids in Mineral Aggregate (VMA), and Void Fill Index (VFA) were 5%, 15%, and 66.28%, respectively, meeting the required standards. At higher plastic content levels (6.5% and 7%), these values slightly increased, indicating a denser mixture that could potentially reduce stability. Specifically, AC WC asphalt with a 6% LDPE plastic mixture achieved average stability of 1594.7 kg, with increased plastic content correlating with improved stability, though also presenting a higher risk of cracking. Among the various tested mixtures, the optimal plastic content for the AC-WC asphalt mixture was identified as 6%. This research highlights the potential for utilizing fly ash and recycled plastic to enhance the performance of asphalt mixtures, contributing to more sustainable road materials and construction practices.
