Abstract
Expansive footing is the causes many problems both(prenominal) during construction and after construction. Chemical stabilization, specifically with lime hydrate, is a vulgar way to stabilize the expansive priming coat. Along with stabilizing the soil lime also lowers the plasticity index, increases workability, and improves the strength, load-deformation, and durability of the soil. The reasons for these improvements are discussed in this paper. Although lime stabilization is a solution to expansive soils it does have a bun in the oven limitations, and should not always be used. One limitation of lime usage, sulfates, is discussed in this paper.

Introduction
In the United States expansive soils cause billions of dollars in damages to infrastructure each year, which is more damage than internal disasters like floods, earthquakes, hurricanes, and tornados cause combined (Jones and Holtz, 1973; Jones and Jones, 1987). Although, unlike the above inborn disasters expansive soils arent deadly, they contri onlye to a lot of economical loss. Expansive soils act so gradually that it can go unnoticed, until all of a sudden the damage is done.



Since they act belatedly the damage is not concentrated in one area, but spread over a wide range of areas (Coduto, 2001).
Expansive soil consists of clay and/or sedimentary rock make up of clay that changes in volume as a result of changes in moisture content, and is usually found in semi-arid regions (Coduto, 2001). When contractors encounter this soil they have four options: 1) Find a new construction site 2) Redesign structure/ metrical unit for poor soil 3) Remove and replace the poor soil with better soil 4) Improve the engineering properties of the soil. Finding a new construction site might seem light and inexpensive, but is not usually practical. Redesigning the structure/foundation is...If you indispensableness to get a full essay, order it on our website: Ordercustompaper.com
