<p><p><strong>References:<br></strong><em>Fox and Cowell (1998)</em></p><p><strong>Method Summary</strong></p><p>Proper installation of rammed aggregate piers requires the aggregate moisture content to be within acceptable limits. Moisture content tests can be run on aggregate samples obtained before placement. Moisture content testing is inappropriate for clean stone.</p><p><strong>Accuracy and Precision</strong></p><p>Reasonably accurate moisture contents can be obtained using oven-dried, fry pan, or Speedy Moisture Meter methods.</p><p><strong>Adequacy of Coverage</strong></p><p>Care should be taken to ensure samples used for testing are representative.</p><p><strong>Implementation Requirements </strong></p><p>This method can easily be implemented in the field (fry pan and Speedy Moisture Meter methods) or the lab (oven-dried method).</p><p><strong>General Comments</strong></p><p>Aggregate moisture content is relatively important for all rammed aggregate pier applications.</p></p>
