The optimum approach developed has been applied to the design method recommended by the American Association of State Highway and Transportation Officials (AASHTO) for the design of flexible pavements. An optimum approach for the design of flexible pavements has been developed which utilizes the anticipated performance of pavement and its life-cycle cost.
