Study on Physical and Chemical Change Behavior of Stabilized Black Cotton Soil for Pavement Subgrade
The soil in the highway material as subgrade plays an important role in the pavement component, which is an integral part of pavement. It is desirable to have the pavement with the good subgrade soil. But this is challenging in the case when the subgrade soil is expansive in nature. In order to obtain the better performance, various soil stabilizers are used to improve the subgrade soil properties. In the present study black cotton soil is used which is expansive in nature and is treated with conventional additive Lime with the dosage of (2, 4, 6, 8, 10% by weight of soil) and non conventional additive. Terrazyme with (50–250 ml/m3 of soil) with the increment of 50 ml and chemical based additive Terrasil with (0.2–1.0 kg/m3) with the increment of 0.2 kg/m3. The study aimed to identify the physical & chemical change behavior of soil when it is stabilized with different additives. Chemical modification in the soil due to additives plays an important role in physical modification of soil. Laboratory test program was aimed at evaluating the potential chemical parameters such as: pH, Silica, Aluminium oxide, Ferrous oxide, Chlorides, Sulphates, Calcium oxide and Magnesium oxide that are responsible to increase the strength and volumetric change behavior of modified soil treated with various additives.
