| Abstract: | With the wide application of geosynthetics in highway engineering, test of geosynthetics plays an important role in design and construction.Problems in the test of geosynthetics were summarized.Effect of tensile rate, sampling method and clamping position on the results of tensile test, and the effect of shear rate and the test method on the results of interface friction test were analyzed.Contradiction between thickness measurement and normal pressure in transverse permeability test was indicated.Based on the discussion, some suggestions were presented.. |
