Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.

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? (b) How many truckloads of borrow pit soil will be required for a 100,000 m3 highway embankment - assuming each truck has a capacity of 10 m3 ?

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.
