Standard compaction tests were performed on a brown-grey clayey-silt (Gs = 2.76). Details and results for the tests are recorded in table 1. You are required to: a) Fill in the blanks of the table for test No. 5. b) Plot dry density Y against moisture content w on the blank engineering paper. Clearly label with numeric values the maximum dry density and optimum moisture content. c) Plot the zero air voids curve on the same paper.
