Reference no: EM131137855

A fi ne-grained soil has 60% clay with LL =220%, PL = 45%, and a natural water content of 6%. A standard Proctor test was carried out in the laboratory and the following data were recorded.

(a) Determine the maximum dry unit weight and optimum water content.

(b) 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.

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