Abstract
Sandy soils are widespread worldwide and are often discovered in many different regions. The
nationwide development of any country takes place rapidly when it has high-rise structures and
better transportation facilities, and soil stabilization plays a significant role in supporting these
infrastructures. This thesis investigates the application of a chemical stabilizer (TX-95) in
combination with a soil binder (SB-95) to optimize the stabilization of sandy soil. The stabilization
technique aims to enhance sandy soils, which are frequently characterized by high permeability
and poor cohesion, in terms of strength and load-bearing capacity. The impact of the SB-95 content
of various compositions was investigated at a constant dosage of the TX-95 throughout different
curing periods using a series of laboratory experiments, including the Unconfined Compressive
Strength (UCS) test & California Bearing Ratio (CBR) test. The major components of the
experiment outcomes demonstrate a substantial improvement in the soil's mechanical properties,
increasing the SB-95 content while maintaining a consistent TX-95 dosage. The enhanced soil
exhibits phenomenal capabilities in terms of compressive strength and load-bearing capacity, as
well as shear strength of up to 825 kPA and CBR value of up to 278%. These findings indicate that
the stabilized soil is appropriate for a variety of engineering applications, including bridges,
embankments, roads, and the foundation of high-rise structures. The combination of the TX-95
and SB-95 offers an effective stabilization approach for the stabilization of sandy soils, leading
significantly to a long-term and sustainable construction practice
