Cement-Treated Sub-bases the unconventional pavement layers known as sub-bases are utilized to enhance the mechanical properties of base and sub-base courses. The typical Constructing method, which uses GSB, WMM as a base layer, also requires a significant amount of material, which drives up the project's material and overall costs. Utilizing a different foundation layer will reduce the thickness of the pavement, saving money and materials while also improving efficiency. The entire surface is disturbed if the bottom coating is wavy, yet the structure varies under load. The road surface has a significant compressive stress due to the transfer of weight from the grain to the tip of the grain, necessitating the removal of a solid layer . . A flexible layer has four layers; Wear a layer, a base coat, a base coat and a subgrade The base that has been treated consists of a complete granular mixture that has been blended with enough water and an appropriate amount of Portland cement to achieve a high concentration. Enough moisture, proper concrete content, thorough mixing, adequate density, and adequate hardness are the fundamental variables that govern the quality of the CTSB. Because of this, this substance thins the crust, saving money on construction. In comparison to those specifications, it shows that this material performs and is stronger than conventional materials. The results show that the CTSB methods saved the greatest money on road construction expenditures. using sub-base and foundation treated with cement rather than the usual base material for Constructing roads.
