Soil Compaction 1. A series of Modified Proctor Tests have been perfomed on a soil that has a unit weight of 26,290.8 N/m³. The volume and mass of the empty mold are 1/30 ft and 1.970 kg, respectively. The test results obtained are as follows: Moisture Content Test Results Point No. Mass of Mass of Can Mass of Can+Moist Mass of Can + Compacted () Soil (g) Dry Soil (g) Soil+Mold (kg) 1 3.673 22.11 205.74 196.33 2 3.798 23.85 194.20 180.54 3 3.927 19.74 196.24 177.92 4 3.983 20.03 187.43 165.71 3.932 21.99 199.59 171.11 c. If the required relative compaction is 98% of MDD, the dry unit weight in the field should be greater than kN/m³.
