3.0 SUMMARY AND CONCLUSIONS <br /> The test program described herein was successful, in achieving the goal of <br /> developing in-place density information for the selected ADC materials. The <br /> authors feel that this program could be duplicated at other sites, and that the results <br /> yielded could be repeated within a reasonably small range. <br /> Thickness measurements require some judgment to determine just where cover <br /> stops and MSW starts, due to the heterogeneous nature of MSW and the somewhat <br /> rough surface to which the ADC is applied. It should also be noted that California <br /> standards for the application of greenwaste ADC call for an average thickness of <br /> between 6" and 12". Both test plots constructed with greenwaste resulted in > 12" <br /> average thickness. <br /> A summary of the test results are presented below: <br /> Shredded greenwaste density had a range of 110.3 Ib/cy, an average of <br /> 776.3 Ib/cy, a standard deviation of 78.0 Ib/cy and a coefficient of variation <br /> of 10.05%. A possible explanation for this variation is that since the lower <br /> result was produced on the sloped test plot, the shredded greenwaste <br /> compacts less readily on a slope than it does on a flat deck. <br /> TASW density had a range of 88.6 Ib/cy, an average of 1,124.8 Ib/cy, a <br /> standard deviation of 62.65 Ib/cy, and a coefficient of variation of 5.57%. <br /> These measures indicate that placement and compaction of TASW was very <br /> consistent during this test program. While TASW showed higher density on <br /> the sloped test plot, no conclusion should be drawn without further testing <br /> and a larger statistical population. <br /> The results from the ADC Test Program conducted on October 11 and 12, 2006, <br /> provide the necessary data to finalize the JTD Amendment. Allied and BAS are <br /> ready to meet with the LEA to integrate the results of this ADC field testing into a <br /> Joint Technical Document (JTD) Amendment. Allied will then prepare and submit <br /> the JTD Amendment to comply with 27 CCR and reconcile LEA concerns with ADC <br /> usage at the FL. <br /> 3-1 <br /> J:\A11ied\Forward\2006.0154 ADC Test\ADC Test Report\Final ADC Test Report Sec 3.doc <br />
