A field density test has been conducted in a compacted fill that is currently under construction.The test results indicate a relative compaction of 101-103%, which made the constructionmanager believe the test must be incorrect. He believes it is impossible for the dry unit weightinthe field to be greater than the maximum dry unit weight from the Proctor compaction test.Explain why the relative compaction in the field could indeedbe greater than 100%.

(a) The following results are obtained from a Standard Proctor compaction test: Mass of soil (kg) Moisture content (%) 1.791 8.4 1.937 10.6 2.038 12.9 2.050 14.4 2.022 16.6 1.985 18.6 The specific gravity of the solids is 2.70, pw= 1000kg/m' and the volume of the compaction mould is 0.945 x 10° m'. Plot the compaction curve and obtain the maximum dry density (MDD) and optimum moisture content (OMC).
. The maximum dry unit weight obtained from a standard compaction test on a silty sand forest road subgrade soil is 110 lb/ft3. The corresponding optimum water content is 26%. The compaction specifications call for compaction to 90% or greater of the maximum dry unit weight by the standard compaction test, and a water content of 2% less than the optimum water content. If the existing natural water content is 17%, how much water, in gallons, must be added per cubic yard of compacted soil to meet the specification?
