ASTM D8167/D8167M

ASTM D8167/D8167M is the ASTM standard for measuring the in-place bulk density of soil and soil-aggregate by a low-activity nuclear method at shallow depth. It is used when a controlled field test is needed to assess compacted materials or existing layers without removing a large sample. By defining a repeatable testing approach, the standard supports more consistent field evaluation, better quality control, and clearer comparisons during construction and inspection.

ASTM D8167/D8167M standard overview

The official title of ASTM D8167/D8167M indicates a test method focused on in-place bulk density measurement using a low-activity nuclear method. Its purpose is to provide a standardized way to evaluate soil and soil-aggregate conditions at shallow depth under field conditions. For product users, this makes the standard relevant to testing workflows that depend on reliable density results, consistent measurement technique, and documentation aligned with ASTM requirements for engineering and quality assurance needs.

Where is ASTM D8167/D8167M used?

This standard is commonly used in field testing situations where soil or soil-aggregate density must be checked in place at shallow depth. It is relevant to compaction verification, construction inspection, and other workflow steps where a nuclear gauge or similar low-activity nuclear equipment may be used. ASTM D8167/D8167M is especially useful when users need a practical method for evaluating installed layers without disrupting the material or delaying ongoing work.

Practical importance of ASTM D8167/D8167M

ASTM D8167/D8167M helps support repeatable field measurements that can be used for compliance checks, acceptance decisions, and quality control records. In procurement and specification settings, it provides a clear technical reference for selecting a test method that fits shallow-depth density evaluation. The standard can also help reduce uncertainty in testing programs by promoting consistent procedures and better alignment between field results and project requirements.
