Large Direct Shear Test Systems

The fully automatic large shear box apparatus ADS-300, ADS-500 and ADS-1000 have been developed and designed according to the latest scientific findings and resulting testing demands (ASTM, EN and DIN).

To determine the friction behaviour of soils, gravels, geo-synthetics, recycling rubble or industrial slag.

Note: customized sample sizes and shear rates available on request.

  • Applications
  • Testing apparatus to determine the internal friction of construction materials and friction parameters of interfaces between different construction material layers, such as: plastic liner/soil, geo-grid/soil, geo-textile/soil, plastic liner/geo-textile, geo-textile/concrete, concrete/asphalt, soil/soil, and gravel
  • The advanced and highly accurate shear box system, developed and exclusively offered by Wille Geotechnik® prevents tilting and wall friction throughout the test
  • A stainless steel water receiver is integrated in the lower and upper shear box for sample saturation
  • Creep test (optional)
  • Semi-automatic or fully automatic PC operation
  • Small and standard shear angles can be measured with high-levels of repeatability
  • Automatic wall friction compensation possible
  • Applicable for automatic test controls and monitoring of parameters and evaluation with shear software modules
