The application of lime can significantly improve the engineering properties of soil. There are essentially two forms of improvement: soil modification and soil stabilization. The use of lime can modify almost all fine-grained soils to some extent, but the most dramatic improvement occurs in clay . For over five decades, lime has been utilized to improve and stabilize roadway soils throughout the state of Texas. From residential streets to the most demanding highways and airfields, lime has proven to be the best solution for solving the problems of the high plasticity clay soils and inadequate base materials.

Lime stabilization is a widely used means of chemically transforming unstable The subgrade in embankment is compacted in two layers, increase pH and hence increase the exchange capacity. Like cement, lime when reacts with wet clay minerals result into increased pH which favors solubility of siliceous and aluminous. Lime can stabilize fine-grained subgrade or subbase. Subgrade stabilization usually involves in situ mixing of soil and stabilizer, and generally requires 3 to 6 per cent of lime by weight of the dry soil. If quicklime is used as a form of lime in soil stabilization, it chemically reacts with water and releases heat.

STABILISATION OF EMBANKMENT CLAY FILLS USING LIME PILES. This paper discusses the long term performance of engineered clay fills by summarising the geotechnical factors that cause embankment failures, and by describing the potential application of clay stabilisation using lime. O’Brien & Chenevert illustrated the utility of their classification by quantitatively analysing the clay mineral composition of specific North American shales which had recognizable problem characteristics ().Thus, the clay mineralogy of the Anhuac Shale (Class 1) is dominated by smectite (40%), forms a so-called “gumbo” clay when drilled and gives rise to a wide variety of problems.

Lime and water were simultaneously poured into the holes, the mixture being topped up four times daily for 2 months. In stiff or strong clay soils holes are formed using a powered auger and the lime is fed in and compacted once the auger has been with­ drawn.

It is believed that lime piles are potentially a simple so­ lution, being both cheap and easy to install using small plant, even in the most remote places.

3) Stabilization: When adequate quantities of lime and water are added, the pH of the soil quickly increases to abovewhich enables the clay particles to break down. Silica and alumina are released and react with calcium from the lime to form calcium-silicate-hydrates (CSH).

A recent study on the performance of a lime treated German embankment placed in is. Stabilization of compacted clay with cement and/or lime containing peat ash. This paper investigates the possibility of the use of cement and/or lime for improvement ground of shallow clay to support highway embankment.

A novel approach to stabilize the clay is to use peat ash as a supplementary material in the compacted and stabilized soil. Lime has been used for many years to stabilize road beds and air fields, but now lime is also being used to stabilize buildings sites.

Lime stabilization is used primarily to upgrade poor quality clay soils in order to provide adequate subgrade support- a prime requisite for good concrete slab performance. embankments, embankment counterweights, a bridge, and/or the excavation of the foundation material resulted in the initiation of this project to determine whether deep in-situ lime stabilization could be used to increase the shearing strength of the founda­ tion soils and, therefore, provide adequate support of the highway embankment.
