    Geogrid evaluation - Break Elongation

    Tensile strength as per ASTM D 6637, method b (wide width). The units are kN/m and both grids are polypropylene. The strengths indicated are for only the Transverse direction. The Machine direction strengths are similar in that the strength at 2% strain is very high.

    Geogrid evaluation - Break Elongation

    Thanks Ron. I think I'm missing something. About failure, isn't failure caused if the force exerted on the gird exceeds the ultimate strength? If that's the case, wouldn't both grids break at the same time once that strength was reached?...also, isn't the difference only that the grid will the...

    Geogrid evaluation - Break Elongation

    Two biaxial polypropylene geogrids each have about the same ultimate strength but one has a lower break elongation. I'm told that the grid with the lower break elongation is superior because it confines the aggregate quicker and thus stabilizes the reinforced layer quicker. Is this a correct...
