18. Lime Stabilization
Lime stabilization is an effective method for enhancing the properties of medium, moderately fine, and fine-grained soils by reducing plasticity and increasing strength and workability. The process involves determining the optimal lime content through mechanical tests, pH measurements, and compaction tests. Key test procedures include the Eades and Grim pH test, unconfined compression tests, and California Bearing Ratio tests to evaluate soil stabilization efficacy.

Key Concepts
- -- Lime Stabilization
- A method of soil modification that involves adding lime to improve soil properties such as strength, workability, and reduction in plasticity.
- -- Eades and Grim pH Test
- A test used to determine the optimum lime content by analyzing the pH of lime-soil mixtures.
- -- California Bearing Ratio (CBR)
- A test to evaluate the strength of soil and its ability to support loads, especially in road and pavement design.
