摘要：The quality of a flexible pavement depends on the strength of its sub-grade soil. The strength of sub-grade isthe major parameters for determining the thickness of pavement. In case of the flexible pavement the sub-grade must beuniform in terms of geotechnical properties like shear strength, compressibility etc. Materials selected for use in theconstruction of sub-grade must have to be of adequate strength and at the same time it must be economical for use. Inview of the above the present investigation has been carried out with easily available materials like lime and rice huskash mixed individually and also in combination with locally available clayey soil in different proportions at optimummoisture content (OMC). Since CBR is an important criterion in flexible pavement design, the strength improvementhas been found in terms of CBR in the present study. The laboratory test results shows marked improvement of strengthof soil with the addition of admixtures in respect of California Bearing Ratio (CBR) in unsoaked and soaked condition.
