Problematic soils have always been of interest to geotechnical engineers. There are many traditional means used to stabilize problematic soil, but they cause environmental problems. Researchers have explored alternative methods for soil stabilization, such as biological approaches. In this study, gelatin and sodium alginate have been investigated as eco-friendly stabilizers for collapsible soil. In order to investigate the effectiveness of mixing collapsible soil with biopolymers, compaction characteristics, shear strength, collapse index, and California bearing ratio (CBR) were estimated before and after treatment. The additives’ effect on the microstructure of the soil was investigated through scanning electron microscopy (SEM) and X-ray diffraction (XRD) tests. The biopolymers were added to the soil in proportions of 0, 0.5, 1, 1.5, 2, 3, and 4%. The findings showed that the collapse index was reduced by about 82% and 95% when the soil was combined with 4% gelatin and 4% sodium alginate, respectively. The soil was stabilized as a result of this modification. The results also showed that with increasing gelatin and sodium alginate content, the optimum moisture content, cohesion intercept, and CBR value increased, but the maximum dry density, Young’s modulus, and friction angle decreased. XRD and SEM analyses revealed that gelatin and sodium alginate changed the soil’s microstructure. According to the results, sodium alginate and gelatin can be used as sustainable stabilizers to take place of the traditional additives. |
