This report summarizes the results of our tests and observations of the compacled wall backfill conducted on May 5, 2004. Actual dates are shown on the enclosed compaction test result sheet. A laboratory compaction test for each soil type was performed to determine the maximum dry density and optimum moisture in accordance with ASTM D-1557-91. Field density tests were performed in accordance with ASTM D-1556-90 sand-cone method as the backfill was placed. Moisture content was determined for each density sample. The results of these tests are shown on the enclosed compaction test result sheet The locations ofthe tests were so placed to provide the best possible coverage. The test locations and final test results are summarized on the compaction test result table. The results of our field density tests and laboratory testing indicate that the retaining wall backfill at the areas tested were compacted to at least 90% ofthe maximum dry density at the tested locations.
