 This study explored the potential of geopolymer concrete as a sustainable material for roadway pavements. Fly ash, manufactured sand, and high molarity alkaline activator were combined to create a geopolymer concrete with excellent mechanical properties. The resulting material exhibited good workability, strength and fatigue properties, making it suitable for use in roadway pavement applications.
