Soil/Geosynthetic interface characterization - The influence of some aspects of the test procedure
It was observed that vertical stress applying time before horizontal displacement starting influences soil/geosynthetic interface behaviour. It was also found the need to define the gap between the upper part of the shear box and the geosynthetic with test vertical stress already applied. Changes were introduced in the test procedure consisting in: - establishing a fixed period of time of the vertical pressure application before starting the shear; - gap definition with vertical pressure applied over the geotextile. Several shear tests were then performed with the modified test procedure and excellent results were found. The number of tests carried out for each vertical stress (four) enabled the determination of interface shear strength parameters characteristic values according to Dixon et al. (2002).
