Traditional soil stabilization methods have been used for many years to improve the load-bearing capacity, durability, and erosion resistance of soil; however, they have some potential drawbacks including air and water pollution, and increased energy consumption. The most used stabilizer, cement considered for its performance and cost-effectiveness is responsible for approximately 5-7% of total carbon dioxide (CO2) emissions worldwide. But nowadays, the global trend incorporates sustainability goals while choosing appropriate soil stabilization. In this direction, various sustainable stabilizers, such as enzymes, and pozzolanas have gained significant attention in recent years. This study explores using a calcium-based mineral stabilizer and GGBS, a byproduct of Iron furnace, as a potential alternative to cement in soil stabilization for flexible pavement construction. The main objective of the paper is to evaluate the mechanical properties of the stabilized soils using CBR followed by the designing of pavements and a comparative life cycle assessment of cement-stabilized flexible pavement construction with mineral-stabilized pavement in SimaPro software, with a cradle-to-gate approach, using the ReCiPe 2016 Endpoint (H) method. The scope of the study is to provide insights into the feasibility and environmental impacts of using mineral stabilizers for soil stabilization in pavement construction. The study's findings indicate that the pozzolanic reaction during the stabilization process played a crucial role in enhancing the CBR values. This improvement led to a reduction in pavement thickness, highlighting that mineral-stabilized pavements demonstrate lower energy requirements and reduced greenhouse gas emissions thus serving as a viable and sustainable choice for pavement construction.
