Soil stabilization is a vital process in civil engineering used to improve the physical properties of soil, enhancing its strength, durability, and load-bearing capacity. It is a key technique in the construction of roads, airports, railways, foundations, and other infrastructure projects where weak or unstable soil conditions could compromise structural integrity.

The primary objective of soil stabilization is to transform poor-quality soil into a more stable and workable material. This is achieved through mechanical, chemical, or biological methods. Mechanical stabilization involves mixing different soil types or compacting the soil to achieve desired density. Chemical stabilization, on the other hand, uses additives such as lime, cement, fly ash, bitumen, or polymers to alter the soil’s composition and performance characteristics. These additives react with soil particles to reduce plasticity, increase cohesion, and minimize moisture sensitivity.

Modern innovations in soil stabilization also include the use of environmentally friendly materials and nanotechnology-based stabilizers that reduce…
