Results Produced Report of direct shear zstm five to nine pages depending on sample type including the following: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment astj facilities used.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. However, a clean, open discontinuity may be free draining, and, d5067, a test on a clean, open discontinuity could be considered a drained test. Sliding on and shearing of the asperities can occur simultaneously. Link to Active This link will always route to the current Active version of the standard.

Two versions can be used to complete the testing configuration: Active view current version of standard.

When the normal force is not sufficient to restrain dilation, the shear mechanism consists of the overriding of the asperities. Samples should be sealed in a plastic wrap inside their shipping container, protected against air, moisture, and direct sunlight. Note 1—The term “normal force” is used in the title instead of normal stress because of the indefinable area of contact and the minimal relative displacement between upper and lower halves of the specimen during testing.

Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour. The shear box consists of two halves, the upper being connected to two rams for reversible shearing action and the lower connected to a ram for normal load application.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the aztm of regulatory limitations prior to use. Displacement and load readings shall be acquired by suitable datalogger asmt has to be add as accessory.

The actual contact areas during testing change, but the actual total contact surface is unmeasurable. It includes procedures for both intact rock strength and sliding friction tests, which can be performed on specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities. During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements. This apparatus was originally developed at Imperial college, London, by Professor E.

Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness.

In situ direct shear testing limits the inherent scale effects found in rock mechanics problems where the laboratory scale may not be representative of the field scale. The test is usually conducted in the undrained state with an applied constant normal load. Therefore, it may be necessary to handle specimens in accordance with Practice D and to document moisture conditions in some manner in the data collection.

Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. Shear box made astk aluminium alloy Maximun axial and shear load capacity: It includes procedures for both intact rock strength and sliding friction tests which can be performed wstm specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities.

In addition, they are representative of the significant digits that generally should be retained. The values given in parentheses are mathematical conversions to inch-pound units, which are provided for information only and are zstm considered standard.

Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour. This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens.

Only one discontinuity per specimen can be tested.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Samples should be concrete or rock cores with a diameter no greater than Therefore nominal area is used for loading purposes and calculations. It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous or have planes of weakness, including natural or artificial discontinuities.

It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. Instructions Samples should be concrete or rock cores with a diameter no greater than However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test.

The apparatus consists of a shear box designed to accept samples not larger than x mm, or alternatively cores up to mm dia. Pervasive discontinuities joints, bedding planes, shear zones, fault zones, schistosity in a rock mass, and genesis, crystallography, texture, fabric, and other factors can cause the rock mass to behave as an anisotropic and heterogeneous discontinuum. The test is usually conducted in the undrained state with an applied constant normal load.

Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. Since this test method makes no provision adtm the measurement of pore pressures, the strength values determined are expressed in terms of total stress, uncorrected for pore pressure. Link to Active This link will always route to the current Active version of the standard. The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during the shearing action and to ensure a constant vertical stress.

Reliable results depend on many factors, Practice D provides a means of evaluating some of those factors.
