Abstract :
Soil stabilization is a technique for improving
and refining engineering qualities. Expansive clay soils
are those whose volume fluctuates as the amount of water
in the soil changes. In civil engineering, soil is one of the
most regularly encountered materials. When
constructions are discovered atop expanding soil,
geotechnical engineers all over the world face major
challenges. Stabilization of soil is the process of enhancing
soil strength by artificial means. They have a tendency to
inflate and shrink, posing a major threat to anything
placed on top of them. The results of an attempt to fortify
and stabilize clay soil with plastic strips are presented in
this research. The plastic strips were produced and added
in three different aspect ratios and three different mixing
ratios (0.4%,0.8%,1.5%) by weight (4mm x 7mm, 8mm x
14mm,12mm x 18.5mm). The experimental findings
revealed that shear strength parameters improved
significantly. The soil's swelling and desiccation cracking
tendencies were also significantly reduced. The optimum
moisture content was reduced significantly, but the
maximum dry density increased little. Based on the
importance of the selection criterion for a specific
engineering activity, the ideal plastic size (aspect ratio)
and plastic content that produces the best outcomes can
be chosen. The difficulties are solved concurrently by
stabilizing vast soils using waste plastic bottles. The
findings of this study point to the possibility of using this
material in expanding soils to increase ground stability in
geotechnical engineering.
