Evaluating the Effect of Coarse Sand in Mechanical Stabilization of Clay Soil.
Subgrade was a very important part of supporting all construction loads on it. If the clay subgrade had unfavorable properties, such as low CBR, the high swelling when applied to the construction of the road subgrade soil would produce soil that is easily damaged. For that, if used in the constructi...

| description | Subgrade was a very important part of supporting all construction loads on it. If the clay subgrade had unfavorable properties, such as low CBR, the high swelling when applied to the construction of the road subgrade soil would produce soil that is easily damaged. For that, if used in the construction of CBR value should be towering so that it can withstand a load on it. The swelling would reduce the volume of soil that is stable when it rains the soil is not swollen, otherwise when the dry season does not shrink too high. Ground improvement methods used in this study were stabilization of coarse sand-clay, using a mixture of percentages of 5%, 10%, 15%, and 20% of the sand. Tests performed on the Zetterberg limits, compaction (standard proctor test), CBR, PSD, and swelling plus tests on sand i.e. sand equivalent and water absorption. The results of the study about a large percentage of the value of sand plasticity index decreased with the increasing sand amount. The CBR value increased for the natural soil to a percentage of 5%, 10%, and 15% of sand, while the percentage of 20% decreased. So in general the best for clay soil stabilization in the Nyanga area where the addition of 15% sand CBR value obtained optimum and could reduce swelling value. |
