Soils
with high plasticity can become highly compressible depending on the parameter
compression index. Same type of soils can have also heaving potential depending
on the expansion index. These type of highly plastic clays can be improved by
adding chemical stabilizers such as lime. In this study, soil samples that are
extremely highly plastic have been taken from clay deposits of Ankara in
Turkey. Hydrated lime has been used as a chemical stabilizer. Firstly,
reference tests have been carried out on natural soil samples. Then the clay is
mixed with the lime agent at different percentages of dry weight of the soil
(1%, 3%, 5%, 7% and 9%) and compressibility characteristics of the improved
soil samples have been determined. All of the results are evaluated and the
changes in compressibility and expansion characteristics have been interpreted
in this paper. Optimum values have been found for both compression and
expansion indices.
