Abstract: Present study deals with the correlation between structural and mechanical characterization of sub-grade soils to increase the strength of soil for road. Clays are generally poor materials for foundations due to large lateral pressure and low resilient modulus. This investigation were carried out with waste products(Agricultural waste) like Rice Husk Ash (RHA) along with various percentages of locally available lime. X-ray fluorescence (XRF), California Bearing Ratio test (C.B.R), Standard Proctor Test, Unconfined Compression Test were done on these samples to characterize the structural and mechanical properties as significant increase in strength properties were observed in the soil samples upon mixing with RHA and lime. It was observed that soaking strength is around 16.8 for the Sample C-3 (Soil+9% RHA). Increase of strength may be due to the reduction of mica in the soil sample. Increase of the silica in the soil sample finally increase the strength and stability. The maximum soaking strength was observed 24.82 for the Sample C-7 ( Soil + 9 % RHA + 8 % Lime). It is obvious because the wt.% mica phase become minimum for this composition. XRF results also reveals that silica and calcium contents are maximum for this composition. So microstructural results revealed that the mica phase may play very important role for maintaining the strength and stability of the soil.
