The ShearTrac III system is capable of performing the consolidation and shearing phases of a 305 mm x 305 mm
(12 x 12 in. by 200 mm (8.0 in) height direct shear test under automatic control for soils and geosynthetics
(geomembrane, geotextile, GCL, geogrid, etc.) as well as for determining the interface frictional properties
of soil and geosynthetics, and internal friction of GCLs.
