Project No. M83O07MT • <br />West Elk Coal Company <br />Julv 25. 1983 <br />• <br />APPENDIX / <br />OBSERVATION AND TESTING <br />Observati. <br />Continuous observation and testing was maintained during the <br />period of July 8, 1983 through July 20, 1983, when compacting <br />operati~us within the project site were underway. Observation and <br />testing by our representative was performed under the supervision <br />of a registered engineer specializing in soil mechanics. <br />Testing <br />Moisture/density relation tests were performed in the <br />laboratory on representative samples of soil material used in <br />the fill in accordance with ASTM Test Method D-698. These results <br />are summarized on Figure 2, Laboratory Moisture Density Test Results. <br />Field Density Tests <br />In-place density tests were performed during our observation <br /> <br />of the fill placement and compaction operations. These tests <br />were performed in accordance with ASTM Test Mehtod D-1556, Sand <br />Cone Method. The test results within the subject area are <br />summarized on Figure 3, Density-Compaction Test Results. The <br />estimated locations of these tests are shown on Figue 1, which <br />is a sketch of the fill area. <br />~Lam~bert ana ~,s,~ociatc.~ <br />CON6ULTING GEOTEGNHICAL ENGINEERS AMO <br />PATE RIAL TESTING <br />
