Geogrid evaluation - Break Elongation
Geogrid evaluation - Break Elongation
(OP)
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 explanation and is it better to have the grid with the lower break elongation?
Looking at the two grids we are comparing the data is:
Type A
Strength at 2% strain 21.0kN
Strength at 5% strain 32.6kN
Ultimate Strength (at break elongation) 33.2kN (5.3% strain)
Type A
Strength at 2% strain 12.0kN
Strength at 5% strain 23.0kN
Ultimate Strength (at break elongation) 31.5kN (10% strain)

Also, are both geogrids polypropylene (PP)?
