GRI ASTM D6241 CBR Puncture Strength of Geotextiles (GT12, GT13, AASHTO M288)

This video describes ASTM D6241 “Standard Test Method for the Static Puncture Strength of Geotextiles and Geotextile Related Products Using a 50-mm Probe,” as it applies to GRI GT12: Standard Specification for “Test Methods and Properties for Nonwoven Geotextiles Used as Protection (or Cushioning) Materials” or GRI GT13: Standard Specification for “Test Methods and Properties for Geotextiles Used as Separation Between Subgrade Soil and Aggregate” These specifications were developed by the Geosynthetic Research Institute (GRI) under the auspices of the Geosynthetic Institute (GSI), with the cooperation of the member organizations for general use by the public. For further information, please consult our website: www.geosynthetic-institute.org. GSI constitutes a diverse assembly of stakeholders who actively engage in the manufacturing, design and use of geosynthetics as engineering materials. GSI’s mission is to develop and transfer knowledge, assess and critique geosynthetics, and provide service to its member organizations. One of the major objectives of the institute is to develop and implement generic specifications of geosynthetics used in Civil Engineering applications all over the world.
