ASTM D6951/D6951M-18-Reapproved2023

Active Standard: Standard Test Method for Use of the Dynamic Cone Penetrometer in Shallow Pavement Applications

ASTM D6951/D6951M

Scope

1.1 This test method covers the measurement of the penetration rate of the dynamic cone penetrometer with an 8 kg [17.6 lb] hammer (8 kg [17.6 lb] DCP) through undisturbed soil or compacted materials, or both. The penetration rate may be related to in situ strength such as an estimated in situ CBR (California Bearing Ratio). A soil density may be estimated (Note 1) if the soil type and moisture content are known. The DCP described in this test method is typically used for pavement applications.

1.2 The test method provides for an optional 4.6 kg [10.1 lb] sliding hammer when the use of the 8 kg [17.6 lb] sliding mass produces excessive penetration in soft ground conditions.

1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
