The max and min dry unit weights of the sand were determined in the laboratory to be 16.5 kN/m3 and 14.6 kN/m3 respectively. The relative density of compaction in the field of the same sand is 70%. What is the relative compaction? (Ans: 96%) What is the dry unit weight? (Ans: 15.84 kN/m3 ) What is the moist unit weight at a moisture content of 10%. (Ans: 17.42 kN/m3 )
