<p><p><strong>Reference(s):</strong></p><p><em>DeJong et al. (2006)<br>Perkins et al. (2000)</em></p><p><strong>Method Summary</strong></p><p>The designer needs to prepare specimens by using bio-treated soils. The samples also need to be compacted in the laboratory, and undisturbed samples from the field are best, if available. The specimen is tested in a triaxial apparatus to obtain stress-strain data.</p><p><strong>Accuracy and Precision</strong></p><p>This method has high accuracy and precision and can test the strength variation of specimens accurately.</p><p><strong>Adequacy of Coverage</strong></p><p>One test may not be representative of the entire site. Engineers should use judgment in specifying the number of tests to be performed and the amount of coverage those results yield.</p><p><strong>Implementation Requirements </strong></p><p>Triaxial testing can be completed by most geotechnical laboratories. The bio-treated specimens should be prepared at specific dimensions appropriate for triaxial testing equipment.</p><p><strong>General Comments</strong></p><p>The triaxial test is a normal strength test in civil engineering. In order to monitor the effect of bio-treated soil, this method is necessary and effective.</p></p>
