Introduction
In many situations in civil engineering practice, geotechnical
engineers are confronted to handle large volumes
of soil, where the soil itself is used as a constructional
material. The importance of compaction as a practical
means of achieving the desired strength, compressibility
and permeability characteristics of soils has been appreciated
since the time early earth structures were built. Compaction
of soil has applications in almost every field of civil
engineering involving soil. So, for a civil engineer, it is very
essential to know the compaction characteristics of natural
soils, and thereby assess their suitability. Also, such kind of
projects requires large quantities of soils, and it is difficult
to obtain such large volume of soil with the desired compaction
characteristics from a single borrow source. In
