In a standard proctor test 1.8 kg of moist soil was filled in the mould of 944 cc after compaction. A soil sample of 100 gm is taken and over-dried for 24 hours at a temperature of 110° C. The weight of the dry sample is 80 gms and the specific gravity of soil particles is 2.7. The theoretical maximum dry density that can be achieved at the given moisture condition is
1
15.81 kN/m3
2
17.2 kN/m3
3
19.1 kN/m3
4
20.2 kN/m3
