While research generally supports the potential advantages of triaxial geogrids in certain aggregate-base reinforcement conditions, the results should not be interpreted as proof of their universal superiority.<\/p>\n

In a 2012 study, Abu-Farsakh, Souci, Voyiadjis and Chen used repeated-load triaxial tests to evaluate geogrid-reinforced granular base materials. The study found that the performance of the materials was affected by the geometry of the geogrids and their tensile modulus, and that a triangular-aperture triaxial product with the highest tensile modulus performed consistently better than the other products tested. The study also reported that geogrid reinforcement reduced permanent deformation under cyclic loading; however, improvements in resilient deformation or resilient modulus were not evident in the tested specimens. It is important to note that these results reflect the specific products and test conditions examined, rather than every biaxial and triaxial geogrid on the market.<\/p>\n

A separate paper, \u2018An Assessment of the Geometry Effect of Geosynthetics for Base Course Reinforcements\u2019, compared typical geosynthetic geometries and concluded that triangular-aperture triaxial geogrids could provide a better confinement effect than rectangular-aperture biaxial geogrids when considering the polymer material and typical product geometries. It also highlighted that conventional uniaxial tensile modulus may be an inadequate standalone indicator of reinforcement effectiveness.<\/p>\n

More recent research published in the Journal of Pipeline? No\u2014the relevant study is in the Journal of Performance of Constructed Facilities\u2014examined critical factors affecting geogrid reinforcement using a loaded wheel tester. It reported that triaxial geogrids performed better than biaxial geogrids with similar tensile strength in the tested aggregate-base conditions. However, tensile strength had a more significant effect on reinforcement than aperture geometry, reinforcing the importance of comparing complete product properties rather than relying on grid shape alone.<\/p>\n
