Soil is significant material found in amplitude by nature, which makes up the base of any construction that is executed. The types of construction carried out are always dependent on soil. Subgrade soil is the most important part of a road pavement. Stabilization is commonly needed if strength of soil is poor. Increase in subgrade strength may lead to economy in the structural thicknesses of a pavement. The main objective of this experimental study is to improve the properties of the clay soil by adding bitumen emulsion (RS1) and to achieve the optimum percentage of bitumen emulsion required to obtain minimum strength required for subgrade layer as set by JKR. An attempt has been made to use bitumen for improving the strength of clay soil which expressed in terms of CBR and UCS values that may prove to be economical. In this study, the whole laboratory work revolves around the basic properties of soil and its strength in terms of CBR and UCS. This is followed by deciding with 0%, 1%, 2%, 3%, 4%, and 5% of stabilizer to show the variation in CBR and UCS value to achieve the best possible strength properties of clay soil with JKR specification. Based on the UCS analysis, 5% of bitumen emulsion stabilized with clay soil gives unconfined compressive strength of 985.91kN/m2 and CBR analysis indicates that CBR value increased effectively up to 80% with increase percentage of bitumen emulsion from 0% to 5%. Hence, it has been observed that clay soil are suitable material to be use as subgrade layer by stabilized with bitumen emulsion.
