This page introduces the Geotechnical Manual, which provides policies and procedures for geotechnical investigation and project development design. It includes the manuals organization and revision history. FIELD DENSITY TEST: 4. GRAIN SIZE ANALYSIS a. Sieve Analysis b. Hydrometer Analysis: 5. DETERMINATION OF CONSISTENCY LIMITS: 6. DENSITY You can see in the plot the peak shear strength and the residual. After the completion of the test the vane was rotated twice and then the residual strength was measured.
References: ASTM D, " Standard test method for The vane shear test is an insitu geotechnical testing methods used to estimate the undrained shear strength of fully saturated clays without disturbance. The test is relatively simple, quick, and provides a costeffective way of estimating the soil shear strength; therefore, it is widely used in geotechnical investigations.
InPlace Vane Shear Test. Use the inplace vane shear test to determine the inplace shearing strength of finegrained soil, which does not lend itself to undisturbed sampling and triaxial testing. The vane shear test can be used to determine the sensitivity of the soil.
After the initial test, the vane is rotated rapidly through several revolutions such that the soil becomes remoulded. The test is repeated on the remoulded soils and the shear strength in remoulded condition is determined. vane shear test (VST)an inplace shear test in which a rod with thin radial vanes at the end is forced into the soil and the resistance to rotation of the rod is determined.

H4212MH Pocket Shear Vane, Metal. The H4212MH provides a quick determination of shear strength values of cohesive soils. H4212 Pocket Shear Vane, Plastic. The Torvane Shear Tester is molded plastic and comes in a plastic Three (3) vane sizes allow for the direct determination of undrained shear strength of soft to stiff clays.
The peak vane value is determined by a calibrated scale ring built into the head assembly. The cross handle is used both to push the vane to the desired test depth and apply the shearing torque. The laboratory vane shear test for the measurement of shear strength of cohesive soils is useful for soils of low shear strength (less than 0.
3 kgcm 2) for which triaxial or unconfined tests cannot be performed. The objective of this test is to find the shear strength of soil. This test is performed to find shear strength of a given (generally very soft) soil specimen.
Vane shear test is a useful method of measuring the shear strength of soft clay. It is a cheaper and quicker method. The test can be f. Vane Shear Test (VST): The instructions for the Vane Shear Test are found in ASTM D 2573. Advantages of the Vane Shear Test are that it provides an assessment of undrained shear strength (S u), the test and equipment are simple; it can measure insitu clay sensitivity (S t), and there is a long history of use in practice.
Guideline for Hand Held Shear Vane Test 3. 0 Procedure 3. 1 Check that the soil type to be tested is cohesive and suitable for Vane Shear Strength determination by the shear vane (very sandy or brittle soils are unsuitable). 3. 2 Record the serial number of the vane head and the vane blade to be c. Triaxial Compression Test (undrained) 8. Consolidation Test Determination of compression index and coefficient of consolidation.
