Shear Test Equipment

ASTM D 5084, D 2850, D 4767

AASHTO T 296, T 297

S-500 Master panel for one test cell. Shown with membranes, permeability cell and

deairing tank (sold separately).

The S-502 Extension Panel offers two additional test po-

sitions (cells) when connected to an S-500 master panel.

The DGSI permeability and triaxial test panels

provide excellent quality for all applicable ASTM

tests. They are built with a light-weight, durable

aluminum frame. Standard features include

acrylic burette housings, plated quick-connect

ttings, standard brass compression ttings and

pressure-rated poly tubing for all plumbing.

Close-up of the differential regulator (E-656) which is unique to the DGSI permeability /

triaxial panel.

For permeability / triaxial testing

you will need the following sources:

• Clean, dry, air

• Water supply

• Drain

• Vacuum

Answer the following before making your selection.

• What type of test(s) will you be performing?

• Triaxial?

> Unconsolidated Undrained, (UU)?

> Consolidated Undrained, (CU)?

> Consolidated Undrained, (CU) with pore pressure?

• Permeability?

• Triaxial and permeability?

• What size samples will you be testing?

• How many simultaneous tests will you be performing?

Section 1 DURHAM GEO SLOPE INDICATOR SOILS Permeability and Triaxial Shear How To Order Step 1. Select Permeability and/or Triaxial Cells ASTM* D 2850, D 4767, D 5084 AASHTO* T 296, T 297 * See Standards Buyer's Guide at www.DGSI.info/3000. The DGSI Triaxial and Permeability Cells are designed to accommodate samples with diameters from 1.4 to 12 in (35 mm to 305 mm).

SOILS Permeability and Triaxial Shear Section 1 DURHAM GEO SLOPE INDICATOR Step 2. Choose your panel(s) Note: Select the type and quantity of each panel based on the number of cells needed for simultaneous testing. One S-500 panel can support up to two S-502 extension panels. The S-502 extension panels cannot operate independently from the S-500. All DGSI panels are built with quality gauges, valves, and fittings. Contact DGSI to request a quote to meet your needs.

DURHAM GEO SLOPE INDICATOR Section 1 SOILS Permeability and Triaxial Shear Step 3. Select Utilities for Panel Selection of proper permeability/triaxial support equipment is essential for ensuring proper panel operation and accurate results. DGSI panel setups require a suitable deairing tank, vacuum pump, compressed air and accessories for proper operation. Clean, dry air and vacuum sources are strongly recommended to maintain consistent performance.

Select Triaxial Load Frame S-600 Triaxial Load Frame ASTM* D 2850, D 4767 AASHTO T 296, T 297 * See Standards Buyer's Guide at www.DGSI.info/3000. The electronically-controlled Triaxial Load Frame has a compression capacity of 10,000 lbf (45 kN). The user friendly Interface/ Controller allows the user to set speed and distance of travel and observe actual platen position during the test.

SOILS Permeability and Triaxial Shear Section 1 DURHAM GEO SLOPE INDICATOR Step 5. For Triaxial, Choose Transducers and Readout Options Skempton’s Value or “B” Value is an important value used in permeability and triaxial testing. DGSI's sensors and readouts are used to monitor pore water pressure within the sample being tested. The end result is used to calculate and determine sample saturation values (“B” Value). Each DGSI transducer requires a subordinate readout device to display the output signal.
