Abstract
Transportation place a vital role over the world. Among the main of transportation, road ways particularly highways being essential important the construction should be good enough to bear the load. Due to poor load bearing capacity the construction of road become difficult on poor soil.to overcome such difficulties some techniques have been introduced to improve the properties & strength of soil to satisfy the design parameters the difficulties faced in road construction especially during the construction of over high plastic clayey soil are of much importance. Poor load bearing subgrade can be treated in several ways including: Lime, Cement, Asphalt stabilization & reinforcement materials. Among which LIME STABILISATION is widely used in the world due to its good performance in road construction easy availability, quick chemical reaction, and cost and of enough benefit. Lime quickly improves the soil condition during construction and can add long term improvements to key soil properties. Adding lime can cause three major soil improvements: / Soil Drying – Reducing the soil moisture content Soil Modification – Reducing soil plasticity, aiding compaction and increasing early strength Lime Stabilization – Increasing long term strength and reducing swell potential
