When using a disposable cone, the device is extracted by driving the hammer upward against layer and the thickness of the layer s cored through recorded. The penetration depth can be increased using drive rod extensions. Combining values from the two systems may result in nonconformance with the d66951.
The DCP described in this test method is typically used for pavement applications. The number of blows and corresponding penetrations are recorded as described in 6. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Disposable Cones for SL970 Dynamic Cone Penetrometer to ASTM D6951
The mass and inertia of the device will change and astj friction along drive rod astk will occur. Report 8 2. Enter the email address you signed up with and we’ll email you a reset link. NOTE 5—An automated data collection system may be used provided it is used after completion of drilling or coring to remove loose measures and records to the nearest 1-mm 0.
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. Link to Active This link will always route to the current Active version of the standard. The penetration depth can be increased using drive zstm extensions.

The test is thus intended to evaluate the in situ strength of a asmt under existing field conditions. Combining values from the two systems may result astm d nonconformance with the standard.

The DCP may be sstm to assess the density of a fairly uniform material by relating density to penetration rate on the same material. The deposable cone tip is first drilling d695 coring an access hole. The mass and inertia of the device ashm change and skin friction along drive rod extensions will occur.
The penetration rate of the 8-kg DCP can be used to estimate in-situ CBR California Bearing Ratioto identify strata thickness, shear strength of strata, and other material characteristics. Combining values from the two systems may result in nonconformance with the standard. The values stated d each system may not be exact equivalents; therefore, each system shall be used independently of the other.
I bought one from Durham Geo. F Footnote D 3 Footnote E. The recorder enters the header information 6.
Forest Service Road Date: Significance and Use 4. However, if drive rod extensions are used, care should be taken when using correlations to estimate other parameters, since these correlations are only appropriate for specific DCP configurations.
