Problem 4: A balloon-type apparatus is used to determine an in-place unit weight for a soil (field density test). The volume of the test hole is 0.000708 cu.m. The weight of the soil obtained from the test hole is 1410 g. The soil sample was dried on a field stone and weighs 1235 g. 1. Compute the water content of the tested soil. 2. Compute the in-place dry unit weight of the tested soil. 3. Determine the $ of compaction for the test result if the soil is part of a compacted earth fill whose maximum unit weight (from laboratory compaction tests) is 18.67 KN/m³.
