The field compaction of an earthwork was checked by an inspection engineer. In the laboratory test, the soil gives a maximum dry density of 1.523 gram/cc at optimum moisture content of 23.4%. Construction specifications require that the soil compacted dry density must be at least 95% of the maximum dry density obtained from laboratory within +2%of optimum moisture content. The following data were obtained in the field using the sand cone test. Volume of soil excavated = 1425 cm3 Weight of soil excavated = 2542 grams Dry weight of soil = 2068 grams What is the in situ moisture content of the soil? O 21.41% O 22.92% O 23.56% O 24.56%

Question
Transcribed Image Text:The field compaction of an earthwork was checked by an inspection engineer. In the laboratory test, the soil
gives a maximum dry density of 1.523 gram/cc at optimum moisture content of 23.4%. Construction
specifications require that the soil compacted dry density must be at least 95% of the maximum dry density
obtained from laboratory within +2%of optimum moisture content.
The following data were obtained in the field using the sand cone test.
Volume of soil excavated = 1425 cm3
Weight of soil excavated = 2542 grams
Dry weight of soil = 2068 grams
What is the in situ moisture content of the soil?
O 21.41%
O 22.92%
O 23.56%
O 24.56%
