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 ifstrength of soil is poor. Increase in subgrade strength may lead to economy in the structuralthicknesses of a pavement. The main objective of this experimental study is to improve theproperties of the clay soil by adding bitumen emulsion (RS1) and to achieve the optimumpercentage of bitumen emulsion required to obtain minimum strength required for subgrade layeras set by JKR. An attempt has been made to use bitumen for improving the strength of clay soilwhich 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 ofCBR and UCS. This is followed by deciding with 0%, 1%, 2%, 3%, 4%, and 5% of stabilizer toshow the variation in CBR and UCS value to achieve the best possible strength properties of claysoil with JKR specification. Based on the UCS analysis, 5% of bitumen emulsion stabilized withclay soil gives unconfined compressive strength of 985.91kN/m2 and CBR analysis indicates thatCBR value increased effectively up to 80% with increase percentage of bitumen emulsion from0% to 5%. Hence, it has been observed that clay soil are suitable material to be use as subgradelayer by stabilized with bitumen emulsion Being a project report submitted to INTI International University as a requirements for Bachelor Of Engineering (Hons) in Civil Engineering January 2018 under the managment and supervision of Faculty of Engineering & Quantity Surveying, INTI International University Dissertations, academic -- Engineering Civil Engineering BCEGI http://intilib.intimal.edu.my/equip-intin/custom/home.jsp
