Abstract: Soil stabilization is a critical technique used to improve the engineering properties of subgrade soils in pavement construction. This method enhances the strength, durability, and overall performance of pavement structures, especially in areas with weak or unstable soil conditions. Various soil stabilization techniques, such as mechanical stabilization, chemical stabilization, and the use of geosynthetics, have been extensively studied and implemented in road infrastructure projects. The effectiveness of these methods depends on factors such as soil type, climate conditions, and traffic loads. This paper presents a comprehensive review of the impact of soil stabilization on pavement performance, focusing on the different stabilization techniques and their influence on the mechanical properties of the subgrade. Key performance indicators, including pavement strength, service life, and maintenance costs, are evaluated based on various case studies and experimental data. Furthermore, the paper explores the challenges faced in selecting appropriate stabilization methods for specific soil types and environmental conditions. The role of advanced materials such as lime, cement, and fly ash in improving the long-term performance of pavements is also examined. By understanding the effects of different stabilization methods, this paper aims to provide guidelines for selecting the most suitable soil stabilization technique for various pavement applications, ultimately contributing to more sustainable and cost-effective road infrastructure.
