When poor quality soil is encountered at construction site, the structure can be designed accordingly or the unsatisfactory soil can be replaced with a suitable soil borrowed from nearby area. Another option is to modify the properties of the existing soil so that it meets the design requirements. This last alternative has led to the development of soil stabilization techniques. Cementing method of soil stabilization is an established procedure of improvement of ground used as sub-grade for pavements. In view of this, apart from the conventional cement, several commercial stabilizers have emerged in the last few years. In line with this, an attempt has been made in the present study to evaluate the effectiveness of one of the new commercial stabilizers viz., Zycobond, Terrasil manufactured by Zydex industries. In this paper, the economic analysis has been done on both flexible and rigid pavements. These cost analyses play a great role on the decision-making stages in selection of pavement types. The pavements were designed under different traffic conditions and soils treated with zycobond and Terrasil. Thickness design of flexible pavement has been conducted as per the IRC:SP:72 2015. Costs are calculated and construction costs have been determined for both flexible and rigid pavements according to BoQ based on MORTH and compared
