Step 5, interpretation results for drawing conclusion: The morphology of mixed soil from the internal angle of friction, the mineralogy of mixed soil from soil cohesive, the moisture content and the density of the mixed soil have been interpreted to identify the best occurrence of safe bearing capacity. The method performed in the present work can be a guideline to be applied to soil mixed design in geotechnical engineering to improve subsoil strength and stiffness at acceptable quality.
