• is decanted away from the compacted fill to the sedimentation <br />pond. This method is represented by placement of coarse material <br />at or near the location of the final placement and the saturated <br />fine refuse material placed in a small temporary pond within the <br />limits of the final pile configuration. The finer refuse is <br />allowed to dewater and then is thoroughly mixed in a 3:1 or <br />greater coarse to fine mixture, placed in lifts not exceeding <br />theee (3) feet and compacted to 908 of maximum standard proctor <br />density with a moisture content of between 12 and 22 percent by <br />weight. <br />A unifocm mixture of the coarse and fine refuse material can be <br />obtained by mixing it as it is being dozed, and then compacting <br />it to the required specifications. Density tests performed during <br />• previous studies along with those conducted by Rocky Mountain <br />Geotechnical have shown that densities in excess of 908 may be <br />achieved by these methods. <br />Once the belt press is installed and operational, it is expected <br />that the moisture content of the fine cefuse will be reduced such <br />that the on site dewatering of the material will not longer be <br />required. Once this condition is achieved, the low strength <br />material within the specified limits from the toe can be removed <br />and direct mixture of coarse and fine material can be performed. <br />A typical detail of the construction section (Section B-B) is <br />shown on Figure 5. <br />Final construction procedures assumes that a satisfactory method <br />9 <br />
