LBTC-310 Geotextile CBR Puncture Strength Fixture

This fixture is suitable for the CBR puncture strength test of geosynthetic materials. It uses a flat‑ended plunger to determine the CBR puncture strength of geosynthetics—specifically, the force measured when the plunger penetrates the specimen at a constant displacement rate. It is intended for use with geotextiles, geomembranes, and their composite products, but is not applicable to materials with apertures greater than 10 mm.
