-32- <br />in Test Pit 1 below a portion of the development rock pile. The <br />samples were saturated, loaded with a confining pressure and allowed <br />to drain prior to being sheared horizontally at a controlled strain <br />rate of .00063 inches per minute. The horizontal displacement and <br />shear stress are recorded on Fig. 16 along with a plot of normal <br />stress vs. shear stress. <br />TWo sets of permeability tests were conducted on samples of <br />material obtained from the site. The first set of tests was conducted <br />on relatively undisturbed samples within the brass liner originally <br />utilized to obtain the samples in the field. The second set of <br />permeability tests was conducted on samples of on -site soil which had <br />been remolded and compacted to 95% of the modified Proctor density <br />(AS"1M D- 1557) near the optimum moisture content. Falling head <br />permeability tests were conducted on both the remolded samples and the <br />in -situ material. Permeability testing on the remolded samples was <br />conducted in general accordance with USER designation E -13. The <br />--' efficients of permeability for the remolded and in -situ samples are <br />mrnarized in Table V. <br />Swell consolidation tests in general accordance with AS <br />dure D -2435 were conducted on samples of the soils at the site in <br />to determine their compressibility or swell Characteristics <br />low to moderate loadings and saturation. The results of the <br />. 11- consolidation tests are presented on Figs. 11 and 12. <br />",eached Rock Drainabilit : The amount of moisture which will drain by <br />,ravity from the leached rock is important to both the operation of <br />the surface facilities and the potential impact on the ground -water <br />
