16. Stabilization Of Soil

The chapter discusses the stabilization and modification of soils in road construction, emphasizing the importance of creating a stable subgrade to support construction activities and enhance pavement effectiveness. It differentiates between soil modification, aimed at creating a working platform, and soil stabilization, which increases the strength of subgrades for long-term pavement performance. Various techniques are explored, including mechanical stabilization and geosynthetic reinforcement, alongside requirements and guidelines for implementation in engineering practices.
