    The new design model is called for especially because the available options contain no or have insufficient indications about the number of required geogrids layers and the mechanical characteristics thereof

    The proposed design method allows to set the number and the mechanical characteristics of geosynthetics layers required for absorbing the horizontal forces generated by self-weight, wheel load and membrane effect. Obviously, more important is the road structure we are designing and lower the design geosynthetic strain shall be: hence for important structures the geosynthetic strain may be limited to 2%, while for less important structures (or when the design conditions afford slightly larger deformations) 3%, 4% or5% geosynthetic strain may be acceptable.

    The method is explained in details here including figures, if you would.
