The research carries out a short feasibility study of a new approach,           which, if proven, would provide a simplified method for the design of           highways, bridges, railways, dams, and structures.  The theory is based         on the following new concepts:  the material does not possess memory;           plastic moduli are selected to produce a set of yield surfaces;                 inelastic deformation occurs immediately when a point in stress space           moves outward from the yield surface; and instabilities are predicted           for important loading paths which are dependent on the initial state of         stress.  This approach shows a promise of providing a consistent model          for the response of sand and other granular materials and would                 realistically predict the observed behavior.
