The design method for secondary roads is based on AASHO Road Test Results and Virginia's design experience. It is divided into two parts. (1) the evaluation of the soil support value of the subgrade, the thickness equivalencies of the paving materials, and the traffic in terms of vehicles per day; and (2) design considerations such as the determination of the required thickness index of the pavement and the selection of the materials and layer thicknesses to meet the design thickness index.
