Pavements are a assortment of materials. These materials, their associated properties, and their interactions determine the properties of the resultant pavement. Thus, a good understanding of these materials, how they are characterized, and how they perform is fundamental to understanding pavement. The materials which are used in the construction of highway are requires not only a meticulous understanding of the soil and aggregate properties but also the binding materials. soil and aggregate properties affect pavement stability and durability and binding materials may be added to improve these pavement features. Soil is considered as a complex material or deposition of earth material, which includes widely different materials like boulders, sands, gravels, clays and silts. These earth material derived naturally by the mechanical and chemical disintegration of rocks or decay of vegetation, that can be excavated by manual or mechanical means depending on the availability. The supporting soil underneath pavement and constructed road is called sub grade. Undisturbed soil underneath the pavement is called natural subgrade. Compacted sub grade is the soil compacted by controlled movement of heavy compactors. The performance of pavements depends to a large extent on the strength and stiffness of the sub grade. CBR test is important method of evaluating the sub grade strength, among the various methods but quick estimation of CBR is most important for highway engineer so this study is focus on comparison of soaked and unsoaked CBR value. This Study is an attempt to understand the influence of soaking on CBR value subjected to different days of soaking and the corresponding variation in moisture content
