Abstract
Subgrade soil stabilization is one of the primary and major processes in the construction of any highway. This paper evaluates the use of glass fibers in combination with nano-clay to improve the soil engineering properties. We intend to study the effect of adding nano-clay and glass fiber on soil mechanical properties, especially Shear parameters, using clayey soil with low liquid limit. The both ratios of glass fiber and nano-clay added to the soil are between 0.5% and 1.5%. Results of this study showed that nano glass fibers and nano-clay can be very effective in improving mechanical properties of clay. Adding nano particles in clay negatively affects the failure strain, but the increase in the glass fibers contents is connected with the increase in failure strain. Also, binary usage of fiber and nano- particles had a remarkable improvement appearing in clay strength than using the single type of fiber. It was found that a considerable shear strength increase up to 84% could be achieved depending on both the ratios of glass fiber and nano-clay that is used to improve the soil. In addition, the experiment results show that, binary usage of fiber and nano-clay can increase the unconfined compression strength of soil.
