These methods apply to all deep foundations, referred to herein as pilesthat function in a manner similar to driven piles or cast-in-place piles, regardless of their method of installation, and may be used for testing single piles or pile groups.
Compression Load Tests provide the most reliable relationship between the axial load applied to a deep foundation and the resulting axial movement. The quality of the result produced by this test method is dependent on the competence of the personnel performing it, and awtm suitability of the equipment and facilities used. Tests that achieve a failure load qstm help the designer improve the efficiency of the foundation by reducing the piling length, quantity, or size.
aztm Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. Grout Systems Incorporated Grout Systems.

This standard also includes illustrations and appendices intended only for explanatory or advisory use. Test results can be atm to determine if the pile or pile group has an ultimate static capacity and a deflection at astn load satisfactory to support a specific foundation.
Link to Active This link will always route to the current Active version of the standard. The test measures the axial deflection of a vertical or inclined deep foundation when loaded in static axial compression.
How one applies the results obtained using this standard is beyond its scope.
When performed as part of a multiple-pile test program, the designer may also use the results to assess the viability of different piling types and the variability of the test site. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Cyclic Loading Test Optional. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Constant Rate of Penetration Test Optional. A foundation designer may evaluate the test results to determine if, after applying an appropriate factor of safety, the pile or pile group has an ultimate static capacity and a deflection at service load satisfactory to support a specific foundation. See Appendix X1 for comments regarding some of the factors influencing the interpretation of test results.
Historical Version s – view previous versions of standard. Interested in compression pile load testing, contact the experienced team at Grout Systems. Test results may also provide information used to assess the distribution of side shear resistance along the pile shaft, the amount of end bearing developed at the pile toe, and the long-term load-deflection behavior.
These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
Constant Time Interval Test Optional. The test results may not represent the long-term performance of a deep foundation. The engineer in responsible charge of the foundation design, referred to herein as the Engineer, shall approve any deviations, deletions, or additions to the requirements of this standard.
Compression (ASTM D1143)
Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Grout Systems performs compression load asm based on ASTM D, the standard test method for deep foundations under static axial compressive load. In this system, the pound [lbf] represents a unit of force [weight], while the unit for mass is slugs.
When performed as part of a multiple-pile test program, the results may also be used to assess the viability of different piling types and the variability of the test site.
Imperative sentences indicate mandatory provisions. Combining values from the two systems may result in non-conformance with the standard. Constant Movement Increment Test Optional.
Compression load tests apply to all deep foundations that function in a manner similar to driven piles or cast-in-place piles, regardless of their method of installation, and may be used for testing single piles or pile groups. Loading in Excess of Maintained Test Optional. Test results may also provide information used to assess the distribution of side shear resistance along the pile shaft, the amount of end bearing developed at the pile toe, and the long-term load-deflection behavior.
