Many types of geotextile related products (GRP) have a structure composed of single elements connected by “junctions” : geogrids and geocells are the most obvious examples. Other types of GRP, namely the geocomposites, are made of singleGRP connected in different ways (thennal bonding, glue, hot melt, etc.) but generally the contact between two elements occurs along lines orin specific points, and not uniformly on the whole surface: therefore these lines or points may be regarded as “junctures”. In many applications the connections assume a structural importance, hence their mechanical strength needs to be tested throughly. The paper presents an organic proposal about the connection tests for geogrids, geocells and geocomposites. Preliminary results are also presented.
