Polymeric materials are now being used in soil stabilization because they are available and free of dangerous, non-toxic, environmentally friendly materials. In this study, polyacrylamides, a white powdery substance that is tasteless and odorless, non-toxic, and characterized by high water absorption properties as it works to attract soil particles with one another and thereby change the structure of the soil, was used as a soil binder to improve clayey soils properties such as their strength and compressibility. The polymer was added to it by weight of the soil in five different proportions: 0.25, 0.5, 1, 2, and 4%. It was determined that there has been a considerable improvement in the soil's properties in terms of boosting the strength and durability of the soil after the addition. By adding more polymer to the soil, the strength and durability of the soil were improved. It was determined that 0.5% of the used polymer produces the best results in increasing the shear strength and compressibility of clayey soil. In the confined compression test, the soil's strength peaked at 0.5% of the added polymer, where the shear strength (Cu) magnitude was (78.7, 83.45, and 100.15 kPa) for 0, 7, and 14 days, respectively, and the improvement percent was 75%, 70%, and 68% at times (0, 7 and 14) days, respectively. Also, there was a significant reduction in the compression index of about 71 % where Cc for natural was 0.21 where it became 0.06 at 0.5 % polymer.
