A soil sample was taken from a proposed embankment that is to be used as compacted fill for a building foundation. The sample was sent to a soil laboratory for a compaction test. Standard Proctor Method B was performed and the results showed maximum dry unit weight of 19.45 kN/m³ and optimum moisture content is 12.6%. During placement, the contractor had a field compaction test performed and the field test results were in-place dry unit weight of 18.65 kN/m³ and moisture content 11.6%. Required Determine the percent compaction achieved by the contractor, the the nearest 10th of a percent.

A compacted fill, currently under construction, will support a proposed supermarket. One of the field density tests in this fill gave a unit weight of 121 lb/ft³ and a moisture content of 12.5%. A series of modified Proctor tests have also been performed on the fill soils per ASTM D1557, and they gave a maximum dry unit weight of 117 lb/ft³ and an optimum moisture content of 13.0%. Compute the relative compaction based on the modified Proctor test and determine whether or not it satisfies the normal compaction specification for such a project.

Read the question carefully and give me both a&b right solutions. A proctor compaction test in the laboratory on a borrow pit soil gives maximum unit weight of 19 kN/m3 and optimum water content of 11.5%. The bulk unit weight and water content of the soil in the borrow pit are 17.2 kN/m3 and 8.2%, respectively. A highway fill is to be constructed using this soil. The specifications require the fill to be compacted to 95% Proctor compaction. (a) What is the additional weight of water per unit volume required to bring the moisture content to the optimum value to achieve 95% Proctor compaction?
