<p><p><strong>References:<br></strong><em>Braithwaite and du Preez (1997)<br>Serridge and Synac (2006)</em></p><p><strong>Method Summary</strong></p><p>The plate load test uses a steel bearing plate and a hydraulic jack to apply a known load and measures the resulting surface deflection. The tests results can be used to determine the modulus of subgrade reaction. Large-scale plate load tests provide a direct measure of whether the specified settlement/strength criteria have been met (Braithwaite and du Preez 1997). Plate bearing tests carried out at different levels during the trials and after treatment may enable more accurate appraisal of the bearing characteristics of treated fills (Serridge and Synac 2006).</p><p><strong>Accuracy and Precision</strong></p><p>Level of accuracy and precision of this procedure has not been documented (ASTM D1195).</p><p><strong>Adequacy of Coverage</strong></p><p>Frequency of testing should be related to the uniformity of ground conditions but should typically not be less than one test per 22,000 SF (2000 m²) of treated area.</p><p><strong>Implementation Requirements </strong></p><p>Some experience and special equipment is necessary.</p><p><strong>General Comments </strong></p><p>Plate load tests with RIC are used to determine improved bearing characteristics.</p></p>
