pavement thickness. The design of a flexible pavement structure is not unlike the design of a fabricated structure in that the stresses in each member must be determined and each member de­ signed to withstand those stresses. In the case of a flexible pavement, the pressures produced by loads are distributed through the structure to the subgrade.
