Loading in Excess of Maintained Test Optional. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
Compression (ASTM D) | Grout Systems
Test results can be evaluated to determine if the pile or pile group has an atm static capacity and a deflection at service load satisfactory to support a specific foundation. 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. In this system, the pound [lbf] represents a unit of force [weight], while the unit for mass is slugs.
Imperative sentences indicate mandatory provisions. A foundation designer may evaluate the test ast 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.
Combining values from the two systems may result in non-conformance with the astk. Compression Load Tests provide the most reliable relationship between the axial load applied to a deep foundation and the resulting axial movement.
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. Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. How one applies the results obtained using this standard is beyond its scope.
See Appendix X1 for comments regarding some of the factors influencing the interpretation of test results. The text of this standard references notes and footnotes which provide explanatory material. Interested in compression pile load testing, contact the experienced team at Grout Systems.
Constant Time Interval Test Optional. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
Historical Version s – view previous versions of standard. The test measures the axial deflection of a vertical or inclined e1143 foundation when loaded in static axial compression. This standard also includes illustrations and appendices intended only for explanatory or advisory use.

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. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. The quality of the result produced by this test method is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.
Tests that achieve a failure load may help the designer improve the efficiency of the foundation by reducing the piling length, quantity, or size.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
