<p><p><strong>References:<br></strong><em>Rogbeck et al. (2003)</em></p><p><strong>Method Summary</strong></p><p>This test is performed in a laboratory and functions to determine the tensile strength of the soil nail. Opposing outward loads are applied to each end of the representative nail until tensile failure occurs.</p><p><strong>Accuracy and Precision</strong></p><p>This is a highly accurate and precise laboratory test.</p><p><strong>Adequacy of Coverage</strong></p><p>One test to failure per batch can be used to represent the entire batch. Tension testing gives a numerical value, which can be compared to the required design parameters and will provide an indication of how well the soil nail should perform in the field</p><p><strong>Implementation Requirements </strong></p><p>Given the correct equipment, tension testing requires minimal training and time investment.</p><p><strong>General Comments</strong></p><p>Results from tension testing nails in the laboratory can be used to represent a batch of nails to be installed in the field. Tension testing is used for both method and performance approach specifications. Typically, nails are delivered with a certificate from the mill stating that the nails have adequate strength, according to ASTM standards.</p></p>
