Question

A fine-grained soil has 60% clay with LL 220%, PL 545%, and a natural water content of 6%. A standard Proctor test was carried out in the laboratory and the following data were recorded

Diameter of mold = 101.40 mm
Height of mold = 116.70 mm
Mass of mold = 4196.50 gram

Specific gravity, Gs = 2.69

Determine the maximum dry unit weight and optimum water content.
If the desired compaction in the field is 95% of the standard Proctor test results, what values of dry unit weight and water content would you specify?
Explain why you select these values.
What field equipment would you specify to compact the soil in the field, and why?

How would you check that the specified dry unit weight and water content are achieved in the field?
