The raw materials of the stone column of crushed stone, stone or gravel are available in almost a place.
Many researchers have tried to use additional materials (additives) with the crush stone such as lime, cement, bitumen geotextile or steel in very few percentages and others.
The following equation was obtained by carrying out statistical analysis using the SPSS (Statistical Package for the Social Sciences) program form the present experimental work and previous studies data.
