Question: A Proctor test was performed on a soil which has a specific gravity of solids of 2.71. For the water content and total unit weight

A Proctor test was performed on a soil which has a specific gravity of solids of 2.71. For the water content and total unit weight data below:

(a) Plot the moisture-dry density curve.

(b) Find the maximum dry density and optimum moisture content.

(c) Determine the moisture range permitted if a contractor must achieve 90% relative compaction.

(d) What volume of water, in ft3, must be added to obtain 1 yd3 of soil at the maximum dry density if the soil is originally at 10% water content?
