A sand cone test has been performed in a recently compacted fill. The test results obtained are as follows: Initial weight of sand cone + sand = 13.51 lb Final weight of sand cone + sand = 4.26 lb Weight of sand to fill cone = 2.12 lb Weight of soil from hole + bucket = 12.42 lb Weight of bucket = 1.21 lb Moisture content test: Mass of empty moisture content can = 23.11 g Mass of moist soil + can = = 273.93 g Mass of oven-dried soil + can = 250.10 g The sand used in the sand cone had a unit weight of 81.0 lb/ft³, and the fill had a maximum dry unit weight of 121 lb/ft³ and an optimum moisture content of 11.7%, based on the modified Proctor test. Compute the relative compaction based on the modified Proctor test.

Question
Transcribed Image Text:A sand cone test has been performed in a recently compacted fill. The test results
obtained are as follows:
Initial weight of sand cone + sand = 13.51 lb
Final weight of sand cone + sand = 4.26 lb
Weight of sand to fill cone = 2.12 lb
Weight of soil from hole + bucket = 12.42 lb
Weight of bucket = 1.21 lb
Moisture content test:
Mass of empty moisture content can = 23.11 g
Mass of moist soil + can = = 273.93 g
Mass of oven-dried soil + can = 250.10 g
The sand used in the sand cone had a unit weight of 81.0 lb/ft³, and the fill had a
maximum dry unit weight of 121 lb/ft³ and an optimum moisture content of 11.7%, based
on the modified Proctor test. Compute the relative compaction based on the modified
Proctor test.
