2.2.2 Compaction tests
The method given in the ASTM D698 (2000) was applied to determine the
maximum dry density (MDD) and the optimum moisture content (OMC) of the
soil samples. The soil mixtures, with and without hydrated lime, were
thoroughly mixed for one hour before performing compaction tests.
De-ionized water was added to the soil mixture. The first series of
compaction tests were aimed at determining the compaction properties of
the untreated soil samples. The second serious of tests were carried out
to determine the compaction properties of the treated soils with various
amounts of hydrated lime.
