There are some kinds of soils in nature which show a significant decrease in volume by increasing the humidity percentage under a fixed pressure.these solis are called collapsible soils. Collapsible soil shows a noticeable decrease in its volume with an increase in its moisture content under fixed stress. This decrease in
volume causes irreversible damages to any structures on collapsible soil and the ones which are under construction. The study of the behavioral characteristics of collapsible soil and its stabilization is crucial. The main purpose of this study is stabilizing collapsible soil and increasing shear strength by adding E.M. Super Repair with different combinations. A sample was collected from Hamidiyeh region near Ahvaz. The primary geotechnical tests were done on the sample. Then shear strength parameters were determined by adding E.M. Super Repair with different combinations. The results show this substance improve the shear strength parameters. The most shear strength has been observed in 1% combination.
