Standard Test Method for Determining the Shear Strength Between Segmental Concrete Units (Modular Concrete Blocks)

Importancia y uso:

5.1 The shear strength between segmental concrete units (with and without geosynthetic reinforcement) is used in design of reinforced soil retaining walls.

5.2 This test is used to determine the shear strength for the design of the facing stability of segmental retaining walls. Performing a series of these shear tests at varying normal loads permits development of a relationship between shear strength and normal load. This relationship may be linear, bilinear, or some other complex mathematical expression.

5.3 This shear strength test is meant to be a performance test (laboratory or field); therefore, it should be conducted using full-scale system components. The conditions for the test are selected by the user and are not for routine testing.

5.4 As a performance test on full-scale system components, it accounts for some of the variables in construction procedures and materials tolerance normally present for these types of retaining wall systems.
