<br />CONCLUSIONS <br />Based on the test hole samples and laboratory analysis of the samples, <br />and subsequent computer computations, it is concluded that the side slopes on <br />the reject pile must be flattened. It is nearly impossible to obtain truly <br />undistributed samples from within any pile of material. Those obtained and <br />tested indicate that the design densities assumed by Armstrong have not been <br />completely obtained in actual practice. This is likely due to the comparatively <br />high moisture content of the reject material as it is placed. <br />To compensate for this condition, flattening of the side slopes to 2-1/2:1 <br />is required. This wi]1 insure that the pile will be stable and that it will meet <br />the required 1.5 factor of safety for such a waste pile. <br />The effect of this action will be to effectively reduce the volume of reject <br />• <br />material which can be placed on the site by approximately 20 to 25%. This means <br />that this site is fully utilized subject to final slope measurements. Anew <br />reject material disposal site must be found, designed and begun at once to avoid <br />the possibility of multiple handling of this material. <br /> <br />
