The interface friction angle and adhesion are measured in the laboratory mainly using the direct shear apparatus in accordance with ASTM-D5321 and ASTM-D6243 standards (Sikwanda et al. 2018). Although these laboratory tests are standardized, the quality of the results can be largely affected by several factors such as specimen gripping systems, shearing rate, applied normal stress, and the type of geosynthetic test specimens (Fox & Stark 2004). Among these factors, the former is considered to be a major source of dissimilarities in the results (Fox & Kim 2008). This is because when the geosynthetic being tested is not sufficiently secured to the shearing blocks by the gripping system, it experiences progressive failure and shear strength that deviates from the actual field performance (Fox et al. 2004). This could lead to unsafe, cost ineffective, etc. design of projects with the respective geosynthetic materials. This research, therefore, was undertaken to investigate the effects of the specimen gripping system on shear strength at the geosynthetic/geosynthetic interface using a direct shear device.
