This study focusses on controlling the rate of permeability of engineered soils using double ring infiltrometer test. Infiltrometer is an equipment that measures the saturated hydraulic conductivity of the soil. The rate of infiltration is the volume of water that penetrates into the soil per unit of time and unit surface area. This method is mainly applicable to relatively uniform fine-grained soils, but is difficult to use in highly pervious or impervious soils and in dry or stiff soils which may fracture when the rings are to be embedded into the soil. The test can be done at the ground surface or at any depth in pits and even on soil with vegetation. This method cannot be conducted when the test surface is below the ground water table. The main purpose of this study is to find out the hydraulic conductivity and hydraulic conductivity of expansive soil for varying percentages of lime content. The soil considered for the study is Highly Plastic Expansive Clayey soil (CH). Initially, double ring infiltrometer test is conducted over expansive soil without engineering it with lime. Then, in the upcoming trails, lime is added to the test soil pit with different percentages as following: 0%, 2.5%, 5%, 7.5%, and 10%, respectively, and double ring infiltrometer test is carried out for each trail. From the test results, it has been observed that the hydraulic conductivity and rate of infiltration of the expansive soil tend to increase, then decrease with increase in lime percentage as the plasticity and Maximum Dry Density (MDD) of the soil tend to decrease while Optimum Moisture Content (OMC) tend to increase and found that 5% lime is the ideal percentage to control the hydraulic conductivity of the soil.
