In this paper, the durability of the pavement structure was evaluated using the theoretical design method when various pavement design criteria including Japan were applied, and the life cycle cost (hereinafter LCC) was compared. When AC layer thickness and baseboard thickness are changed by using theoretical design method, it can be easily examined which part is critical in design.
