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 ?
