A sand cone test is performed in a recently compacted lift. The test results are as follows: Sand Cone Test (field data): Weight of soil from hole + bucket = 12.12 lb Weight of bucket = 1.21 lb Initial weight of sand cone + sand = 13.51 lb Final weight of sand cone + sand = 4.26 lb Sand Cone Test (lab calibrations): Weight of sand to fill cone = 2.12 lb Average unit weight of sand in hole = 81 pcf Sand type and specific gravity = SP, 2.66 Water Content Test (microwave drying): Mass of empty moisture content can = 23.11 g Mass of moist soil + can = 273.93 Mass of oven-dried soil + can = 250.10 g Modified Proctor compaction test results for the fill soil are summarized below. Use the data above and this figure to estimate the percent relative compaction of the recently placed lift. 120 118 e 116 Dry Unit Weight - pcf 114 112 O o 110 108 6 7 8 9 10 11 12 13 14 Water Content - %
