The following data were obtained from a field density test on a compacted fill of sandy clay. Laboratory moisture density tests on the fill material indicated a maximum dry density of 1.92 Mg/m3 at an optimum water content of 11%. What was the percent compaction of the fill? Was the fill water content above or below optimum? Mass of the moist soil removed from the  test hole = 1038 g Mass of the soil after oven drying = 914 g Volume of the test hole = 478.55  cm
