With the shearing rates described in this standard, d253 lenses, if present, will allow total or partial drainage. It is beyond the scope of this standard to recommend applicability of vane testing for geotechnical analysis. Reliable results depend on many factors; Standard Practice D provides a means of evaluating some of those factors.

ASTM D 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. This method does not address specifically marine testing where special test requirements or variations in equipment may be required. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

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. English Imperial units are given in parentheses. 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.

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. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing.

Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Very sensitive soils can be remolded during vane insertion. Active view current version of standard. Some apparatuses have the vane retracted in protective shoe for advancement and incremental testing.

In addition they are representative of the significant digits that generally should be retained. Referenced Documents d25773 separately The documents listed below are referenced within the subject standard but are not provided atm part of the standard.

Since vane shear strength values are most always higher than field strengths for analyses 5. The test is not aztm for sandy soils which may allow drainage during the test. The values in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Work Item s – proposed revisions of this standard. 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 Subsurface geotechnical explorations are reported in accordance with Practice D This s2573 does not address specifically marine testing where d5273 test requirements or variations in equipment may be required.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. In this system, the pound lbf represents a unit of force weightwhile the unit for mass is slugs.

For more information on how these tests are used for soft ground site exploration refer to Ladd and DeGroot. It is very beneficial to sample the soil either before or after testing, to understand the drainage conditions permeability of the soil tested. The test is applicable to soils with undrained strengths of less than kPa [2 tsf]. Some apparatuses have the vane retracted in a protective shoe for advancement and incremental testing. The test is not applicable for sandy soils or non-plastic silts, which may allow drainage during the test.

Sampling, such as with thin wall tubes D is often combined with vane testing. The agency requesting the testing must interpret these data to determine applicability for strength analysis.

For information on the general use of these correction factors, consult Appendix X1.

aetm Work Item s – proposed revisions of this standard. It is important to check the soil type being tested. 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.
