India's expanding road network is vital for its development, but conventional construction methods using natural aggregates raise environmental concerns due to high energy consumption and CO2 emissions. This study explores the potential of geopolymer stabilised material, a sustainable alternative that utilizes fly ash (FA) and reclaimed asphalt pavement (RAP) to mitigate these issues. FA-based geopolymers harness the pozzolanic activity of fly ash to achieve comparable or improved mechanical and morphological properties compared to traditional concrete. By analysing existing literature, this review examines the impact of FA-based geopolymer stabilized with RAP on various performance aspects such as morphological characteristics, compressive strength, resilient modulus, and durability. This approach promotes a circular economy by utilizing waste materials (RAP) and reduces reliance on virgin resources. The findings highlight the potential for cost-effective and environmentally friendly construction solutions using readily available materials.
