Soil compaction is one of the very most critical components in the engineering of highway embankments, globe dams, foundations and many other engineering structure. Earth must be compacted with their unit weights, increase the strength attribute which improve the bearing capacity of foundations designed over them. Earth is compacted by detatching air and normal water from its pore space.
Compaction is an alteration in soil structure, not just an increase in earth density. Healthy soils have a variety of pore sizes, while compacted soils have mostly small pores. In general, Land compaction is defined as the technique of mechanically increasing the density of ground. In development, this is a significant part of the building process. Almost all types of building sites and development projects utilize mechanical compaction techniques.
