Unsaturated soils and soils with higher permeability, in rapid shear, can dilate or collapse and generate negative or positive pore pressures which may, or may not, dissipate in the shearing process. Sampling, such as with thin wall tubes D is often combined with vane testing.

ASTM D2573

Very sensitive soils can be remolded during vane insertion. Active view current version of standard. It is very beneficial to sample the soil either before or after testing, to understand the drainage conditions permeability of the soil tested. Reliable results depend on v2573 factors; Standard Practice D provides a means of evaluating some of those factors.

Combining values from the two systems may result in non-conformance with the standard. In addition they are representative of the significant digits that generally should be retained. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Subsurface geotechnical explorations are reported in accordance with Practice D In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs. The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

English Imperial units are given in parentheses. Link to Active This link will always route to the current Active version of the standard. For information on the general use of these correction factors, consult Appendix X1. Subsurface geotechnical explorations are reported in accordance with practice D With the shearing rates described in this standard, sand lenses, if present, will allow total or partial drainage.

Since vane shear strength values are most always higher than field strengths for analyses 5. 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.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. Link to Active This link will always route to the current Active version of the standard. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It is beyond the scope of this standard to recommend applicability of vane testing for geotechnical analysis. Work Item s – proposed revisions of this standard. For more information on how these tests are used for soft ground site exploration refer to Ladd and DeGroot.

Some apparatuses have the vane retracted in protective shoe for advancement and incremental testing. Some apparatuses have d2537 vane retracted in a protective shoe for advancement and incremental testing. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. Reporting d253 test results in units other than SI shall not be regarded as nonconformance with this test method.

The test is not applicable for sandy soils which may allow drainage during the test.

This method does not address specifically marine testing where special test requirements or variations in equipment may be required. The test is applicable to soils with undrained strengths of less than kPa [2 tsf].

It zstm important to check the soil type being tested. The agency requesting the testing must interpret these data to determine applicability for strength analysis.

The values in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

This method does not address specifically marine testing where special test requirements or variations in equipment may be required. The test is not applicable for sandy soils or non-plastic silts, which d22573 allow drainage during the test. Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results.
