Introduction
The term compaction is used in the description of the densification process of a
material by mechanical means. The increase in density is obtained by decreasing
the amount of air that is in the void spaces of the material, keeping the moisture
content relatively constant. In real life, compaction is done on materials that will be
used for filling in the construction of embankments, but the material can also be used
in situ in land improvement projects. The main objective of the compaction is to
improve the engineering properties of the material in some aspects such as:
Increase the shear strength, and consequently improve the stability, embankments
and load capacity of foundations and pavements. Reduce compressibility and,
consequently, reduce settlements. Reduce the void ratio and, consequently, reduce
permeability. Reduce the potential for expansion, contraction or expansion by
freezing.
