The device determines the internal friction of construction materials e.g. soils, aggregates, gravels, geomembranes, geotextiles, GCL (Geosynthetic clay liner), recycling rubble Brick rubble, Colliery spoils, an industrial slag. The interface friction parameters between different construction material could be also determined by the device e.g. geotextile /soil, geotextile / concrete, asphalt/concrete, geogrid/soil, etc.
