  • Abstract:
  • Waste Foundry Sand (WFS) is increasingly utilized in the seafood processing sector due to rising waste disposal costs and environmental concerns, despite large quantities still ending up in landfills globally, including in India and the UK. Crushed palm kernel shell (CPKS) is an effective partial replacement for coarse or fine aggregates in asphalt concrete, with varying substitution levels based on traffic intensity: up to 80% for light traffic, 60% for moderate traffic, and 20% for heavy traffic. Additionally, palm kernel shells can replace up to 80% of fine aggregate across traffic conditions, offering a cost-effective, eco-friendly alternative that reduces reliance on natural aggregates. This research evaluates 13 combination ratios using bitumen VG-30 as a binder. WFS was substituted for fine aggregates at 0%, 8%, 16%, 24%, 32%, and 40%, while palm kernel hulls were similarly substituted at the same percentages. For analysis of these aggregate tests like as impact value, crushing strength and abrasion test, Marshall stability test and Indirect dry and wet tensile strength test is performed. After analysis of test results recommended mix will be known which are beneficial for the further studies.
