Abstract: The traffic volume counts to be carried and the strength of the subgrade soil are used to design the different levels of pavement that must be placed over it. The strength of the subgrade is commonly expressed as a ratio known as the California Bearing Ratio, abbreviated as CBR. When the subgrade is weaker, thicker layers are required, whereas when the subgrade is stronger, thinner layers are sufficient. When we can understand how the strength of these soils is affected by variations in saturation, it will be much easier to design and maintain stronger structures. CBR resistance values for soils utilized in the subgrademay vary to a greater extent due to the saturation of the subgrade. Hence, throughout this study,variation in the soaking degreehas been tried and in turn the saturation level in twosoiltypes and engineering properties of soils and CBR at different levels of saturation are studied. The engineering properties that wereevaluated after the soaking of three days were worst and consideringfine-grained soils, it is found to be same after the end of day 4.
Keywords: Compaction, CBR (California Bearing Ratio), subgrade, saturation levels.
