4.1 Data from these tests may be used for structural and geomechanical design purposes. Adequate safety factors, based on engineering judgment must be determined by the user. Note 2: Sampling procedures for in-situ specimens have a major
influence on test results. Specimens carefully trimmed in the
laboratory from large block samples taken in the field have the
least chance of fracturing prior to testing. Sample preparation
methods of laboratory-fabricated specimens also have a major
influence on test results. Specimens should be fabricated in
accordance with Test Method D4320.
Note 3: 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. Agencies that
meet the criteria of Practice D3740 are generally considered capable of
competent and objective testing, sampling, and inspection. Users of
this test method are cautioned that compliance with Practice
D3740 does not in itself
assure reliable results. Reliable results depend on many factors;
Practice D3740 provides a
means of evaluating some of those factors.

1.1 This test method covers the determination of long-term strength and deformation of a cylindrical specimen of either a (undisturbed) field sample or laboratory-fabricated chemical grouted soil when it is sheared undrained in compression under a constant sustained load. Note 1: The voids of chemical grouted soils are most often
substantially filled with grout. Thus, pore pressures are unlikely
to develop. This test method is not applicable to partially grouted
soils in which substantial pore pressures may develop. If pore
pressures must be measured, reference is made to Test Method
D4767 for equipment and
procedures.
1.2 This test method provides data useful in determining strength and deformation properties of chemical grouted soils subjected to sustained loads. Mohr strength envelopes may also be determined. 1.3 The determination of strength envelopes and the development of relationships to aid in interpreting and evaluating test results are left to the engineer or office requesting the test. 1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026. 1.5 The values stated in either SI or inch-pound units shall be regarded separately as standard. The values in each system may not be exact equivalents, therefore, each system must be used independently of the other, without combining values in any way. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. 1.7 This test method offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project's many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. |
