The Effect of Bitumen Stabilized Subgrade on Cost of the Flexible Pavement

In countries where freight transportation is mostly done by highway, the increasing load carrying capacity of heavy vehicles creates the need for strengthening the road pavements. In this study, the effects of stabilized subgrade with asphalt emulsion on flexible pavement thickness and pavement cost were determined. Consequently, the optimum emulsion content and the CBR value has been determined. As a result, it was seen that the thickness of the asphalt pavement and thus the cost of pavement decreased.
