ResumoSoil is the fundamental element of all civil engineering structures acting as support to bear all incoming loads of all kinds safely. For the stability and durability of all structures ,the underlying soil should be sound and not undergo behavioral changes like excessive swelling and shrinkage, decomposition of organic matter , volume changes which all lead to loss of shear strength, excessive settlement. To overcome the above problems, the advanced technology has made a serious concern to control the unpredictable behavior of soil. The focus of the present study is to investigate the effect of addition of coarse sand in different percentages by weight to karewa soils taken from Awantipora AIIMS site. Which leads to the changes on engineering behavior of soil. The inputs of the study is the addition of coarse sand in the different %‘s by weight to soil and the suitable soil samples were made under standard conditions of curing and testing strictly under IS – codal provisions. From the analysis and discussion of results, the results for shear strength parameters (c and φ), CBR %, UCS (kg/m2) and compaction characteristics (OMC and MDD) were finalized and analyzed. The analysis of these results shows the improvement of ‘c’ from 32.72 kPa to 43.50 kPa ,φ value changes from 10.15 to 26.650, CBR value changes from 2.57 to 9.14 and UCS value changes from 100.062kPa to 186.3 kPa for untreated to treated sample.
