In the construction of a road, the compaction specification required was 95% of Proctormaximum dry density at field moisture content within 2% of the optimum moisturecontent. The maximum dry density and optimum moisture content obtained in thelaboratory from the Standard Proctor test were 1.94 gm/cc and 13.5% respectively.

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%.
