ASTM D2573/D2573M is the ASTM standard for the Standard Test Method for Field Vane Shear Test in Saturated Fine-Grained Soils. It provides a recognized approach for measuring soil shear behavior in the field, which is important when evaluating strength conditions in soft, saturated materials. Used properly, this standard helps support consistent geotechnical testing, more dependable engineering decisions, and clearer comparison of results across projects and specifications.

ASTM D2573/D2573M standard overview

This ASTM standard focuses on the field vane shear test as applied to saturated fine-grained soils. The designation D2573/D2573M identifies the test method in both inch-pound and SI units, making it useful for project documentation and technical coordination. By defining a common method for field measurement, ASTM D2573/D2573M supports repeatable testing practices and helps users evaluate soil strength conditions with greater confidence in geotechnical work.

Where is ASTM D2573/D2573M used?

This standard is commonly used in field geotechnical investigations where saturated fine-grained soils must be assessed in place. It is relevant when engineers, consultants, or testing teams need a direct shear strength measurement from soil deposits that may be difficult to sample or disturb during handling. ASTM D2573/D2573M is often referenced in site characterization, foundation planning, and other workflows where field test data help guide design and construction decisions.

Practical importance of ASTM D2573/D2573M

ASTM D2573/D2573M matters because a standardized field test method helps improve consistency in soil strength evaluation. That consistency can support compliance with project requirements, reduce uncertainty during procurement or review of testing services, and improve the reliability of geotechnical reporting. For organizations comparing field data across locations or projects, ASTM D2573/D2573M offers a clear technical basis for quality control, documentation, and risk reduction.
