4.2 For a field test the technician is using a sand with a density of 96.7 pcf in his sand cone test. Calculate the dry density, degree of saturation and moisture content of a compacted fill using the following data that the technician collected: Weight of sand cone bottle before test (full of sand): Final weight of sand cone (some sand remains): Weight of sand needed to fill cone: Weight of fill soil excavated from hole + bucket: Weight of bucket used to collect fill soil: 15.14 Ibs 3.97 Ibs 2.67 Ibs 12.37 Ibs 0.76 Ibs Moisture content of fill soil: Empty can: 48.1 g Can + moist soil: 253.7 g Can + dry soil: 237.1 g
