This test method covers the field vane test in saturated clay
and silt soils for determination of undrained shear strength.
Knowledge of the nature of the soil in which each vane test is to
be made is necessary for assessment of the applicability and
interpretation of the test. The test is not applicable for sandy
soils which may allow drainage during the test.
This test method addresses testing on land and for testing in
drill holes or by self drilling or continuous push methods from the
ground surface. This method does not address specifically marine
testing where special test requirements or variations in equipment
may be required. The user is referred to ASTM STP 1014 for
additional information on in-place vane shear
This method is often used in conjunction with fluid rotary
drilling (D 5783) or hollow-stem augers (D 6151). Some apparatuses
have the vane retracted in protective shoe for advancement and
incremental testing. Sampling, such as with thin wall tubes (D
1587) is often combined with vane testing. Subsurface geotechnical
explorations are reported in accordance with practice (D 5434).
Undrained shear strength and sensitivity of cohesive soils can
also be measured in Unconfined Compression D 2166 and Laboratory
Vane Test (D 4648).
The values stated in SI units are to be regarded as the
standard. English (Imperial) units are given in parentheses.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
