The possible use of geopolymer technology in rigid pavement construction is thoroughly examined in this topic. To meet both engineering needs and environmental concerns, geopolymers provide a unique and ecologically friendly alternative to traditional cement-based materials. The chapter goes into great detail about the ingredients used in geopolymer formulations, such as fly ash, slag, and combinations of the two, highlighting their potential for usage for concrete pavement in addition to lowering waste generation and carbon emissions. To understand how each geopolymer precursor’s preparation methods, which include mixing practices, curing methods, and temperature variations, affect the mechanical and durability characteristics of geopolymer-based pavements, a thorough investigation of these methods is conducted. For performance to be optimized and structural stability to be guaranteed in the long run, this deep understanding is essential. In conclusion, this subject highlights the enormous potential of geopolymer technology to revolutionize pavement engineering. Geopolymer-based rigid pavements have the potential to change the construction landscape by providing environmentally benign options without sacrificing mechanical qualities, encouraging a peaceful coexistence between infrastructural development and environmental preservation. It is projected that ongoing research and development will further improve materials, design approaches, and practical application, ushering in a new era of environment-friendly and high-performing infrastructure. © 2025 Elsevier Ltd.
