ShearTrac III
The ShearTrac III system is capable of performing the consolidation and shearing phase of a 305mm x 305mm ( 12 in.x12in.) direct shear test under automatic control for soils and geosynthetics (geomembranes, geotextile, GCL, geogrid, etc.) as well as determining the interface frictional properties of soil and geosynthetics, and internal friction of GCLs.

Applicable Test Standards

ASTM D-5321 and D-6243
ASTM 3080/T236
BS 1377

Features

Built-in end clamps for geosynthetics testing
Optional grip plates for true internal friction determination for GCLs
Linear bearings for minimum horizontal friction
Two sets of limit switches to prevent over traveling
Built-in 4-channel data acquisition with 16-bit resolution
Two LCD display
Two displacement transducers with 100 mm (4.00 in.) range and 0.002 mm (0.00008 in.) resolution
Two universal shear web type load cells
Accurate displacement rate control from 0.00003 to 10 mm per minute (0.000001 to 0.4 in. per minute)
Built-in electronic controls for automatic display of data and control of test
Fully incremental consolidation test capability
