One of the problems in the construction of the road network is the presence of
expansive clay and loose soil. In Java, expansive clays are generally the result of weathering
rock formations including shale and clay, while soft soils are derived from unconsolidated
sedimentation. In situ stabilization of clay with chemical solutions will be difficult due to the very
low permeability of the soil. Some researchers exploit the phenomenon of electrodynamics, the
nature of the electric and hydraulic coupling to reform clay. This paper examines the
experimental results of clay reclamation in the laboratory. The study was carried out on clay
from Karawang, West Java province, Indonesia, which was injected with saline solution and used
different voltages of 12V, 15V, 18V, and 24V. The success of this experiment will be seen by
comparing the mechanical properties of the soil before and after electrochemical spraying. The
test results show that electrochemical injection with calcium chloride salt solution and a voltage
of 15V can reduce swelling characteristics and increase optimal shear strength.
