on a compacted earth fill. Ottowa sand is used in the cone and is known to have a bulk
density of 100 pcf.
a. From the information given below, determine the in-place dry unit weight of the
tested soil, and the water content.
Soil sample dug from test hole wet weight = 4.62 lb
Dried Weight of soil sample = 4.02 lb
Weight of Ottowa Sand (Sand Cone) to fill test hole = 3.60 lb
b. Determine the percentage of compaction of the tested soil if the laboratory moisture
unit weight curve indicates a dry unit weight of 115 pcf and optimum moisture
content of 13 percent.
