1. Scope
This method covers the procedure for measuring the Aperture Stability Modulus of a geogrid. This method is applicable for various geogrid types and limited to determining the in-plane stability of a geogrid by clamping a center node and measuring the stiffness over an area of the geogrid.
The aperture stability modulus was used in couple of paved and unpaved roads design model adopted by FHWA.
Keywords
aperture stability modulus, in-plane stability, torsional rigidity modulus, torsional stiffness modulus, secant aperture stability modulus.
