Standard Test Method for Determining Connection Strength Between Geosynthetic Reinforcement and Segmental Concrete Units (Modular Concrete Blocks)

Importancia y uso:

5.1 The connection strength between geosynthetic reinforcement and segmental concrete block units is used in design of reinforced soil retaining walls.

5.2 This test is used to determine the connection strength for the design of the connection system formed by segmental concrete block units and geosynthetic reinforcement layers in reinforced soil retaining walls. Performing a series of these connection tests at varying normal loads permits development of a relationship between connection strength and normal load. This relationship may be linear, bilinear, or some other complex mathematical expression.

5.3 This connection 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.
