Laboratory testing was performed on 2-inch cubes of TerraFlex in an unconfined
condition, consistent with testing procedures found in published literature (Horvath
1995). All TerraFlex samples were loaded in a direction perpendicular to the TerraFlex
sheets, which is consistent with the direction of field loading. The room temperature
during testing was approximately 77 degrees Fahrenheit. Descriptions of the test
procedures and materials, tests performed, and results from these tests are provided in the
following sections.
