  • Abstract:
  • Weak subgrade soils are most likely to cause damage to structures such as road pavements. Different types of remedial measures are developed to improve the strength parameters of the subgrade soil. It helps in improving dry density of subgrade soil besides reduction in the permeability and compressibility along with increase its shear strength and the bearing capacity of the subgrade soil. This study aims to improve the subgrade soil strength by chemical stabilization. The identified soil sample with a CBR of 1.76% is mixed with Nano Calcium Chloride and Sugarcane Bagasse Ash to undergo Standard Proctor Test and California Bearing Ratio tests. The percentage addition of Nano Calcium Chloride to the soil is varied as 0.2%, 0.4%, 0.6%, 0.8% and 1% respectively along with the 0.2%, 0.4% and 0.6% and 0.8% addition of Sugarcane Bagasse Ash respectively. The mixed composition is subjected to Standard Proctored and Soaked CBR tests. It is inferred from the results that the Soaked CBR value of soil was attained with the 0.8% of Nano Calcium Chloride and 0.6% of Sugarcane Bagasse Ash additions. The experimental results shows that the results to be applied in the weaker soil abundant areas to minimize the pavement thickness.
