Question
A Standard Proctor Compaction test is performed on a sample of a sandy clay soil obtained from a borrow pit with the following result: Water content (%) 4.2 5.1 7.8 9.2 12.0 Dry unit weight (kN/m3) 16.9 18.1 19.6 19.5 18.5 The sandy clay from the borrow pit has a natural water content of 5.2% and a porosity of 65%. The compaction specifications call for the soil to be compacted at a minimum percent compaction of 95% with a water content equal to the optimum value. How many cubic meters of soil from the borrow pit are needed for each cubic meter of compacted fill? How much water will be required per cubic meter of compacted fill in order to meet the compaction specification?Explanation / Answer
3(5-y)=3(y+4):
