DIRECT SHEAR & PULLOUT TESTER FOR GEOSYNTHETICS TBT1280
TBT1280 Direct Shear & Pullout Tester for Geosynthetics is used to determine the shear resistance and the pullout resistance of a geosynthetic against soil by the direct shear test and by the pullout test separately. It is suitable to geotextiles, geomembranes, geonets and georids. Related Standards: Direct shear test: ISO 12957.1, ASTM D5321 Pullout test: ASTM D6706
