HORIZONTAL DISPLACEMENT(inches) <br /> 19.8 18.4 <br /> STANDARD CONDITIONS: <br /> 1. The"gap"between shear boxes was set at 80 mil(2.0 mm) <br /> 2. The test specimens were flooded during testing unless otherwise noted. <br /> 3. High Normal Stress(>5psi)was applied using air pressure. <br /> 4. Low Normal Stress(<5psi)was applied using dead weights. <br /> 5. The tests were terminated after 3.0"of displacement unless otherwise noted. <br /> 6. Tests were performed in general accordance with ASTM procedure D-5321-92 Method B using a Brainard-Killman LGA 12 direct shear machine <br /> with an effective area of 12"x I Z'. <br /> TEST ORIENTATION. <br /> NORMAL STRESS <br /> TOP BOX W/CLAY LINER <br /> BOTTOM BOX W/FRICTION SAND —7''"°E°7 <HDPE <br /> SPECIAL TEST NOTES. <br /> 1. Each specimen of HPDE was cut to 14"x 20"and clamped into the lower shear box with"channel clamps." <br /> 2. The soil sample was remolded in the upper box to approximately 90%of its maximum dry density and 3 percent over optimum moisture content. <br /> 3. The test was performed in a"wet"or"flooded"condition. <br /> By accepting the data and result represented on this page,Client agrees to limit the liability of Vector Engineering,Inc,from client and all other parties for claims arising out of use of this data to <br /> the cost for the respective test(s)represented hereon,and Client agrees to indemnity and hold harmless Vector from and against all liability in excess of the aforementioned limit. <br /> Report Date: Entered By: Reviewed 13y.
