Test Method Title

(Rock Sliding Friction) Standard Test Method for Performing Laboratory Direct Shear Strength Tests of Rock Specimens Under Constant Normal Force

Reference Number

ASTM D5607 - Sliding Friction

Material

Rock

Test Property

Shear Strength, Friction Angle, Joint Roughness Coefficient

Description of Test

Shear force is applied along a shear plane while maintaining a constant normal force to cause shear displacement. The shear plane is along an open discontinuity, foliation, joint surface, bedding plane, etc. The shear force is recorded and used to calculate friction angle. Any specimen orientation can be tested.

Preferred Test Sample Size

Rock core specimens

Number of Test Specimens

3 or 4

Test Specimen Size

In most cases, the least cross-sectional dimension of the specimen should be at least 10 times the largest grain size in the specimen. The test plane should have a minimum area of 1900 mm2 (3 in2). Specimen should fit within 6" diameter shear rings.
