A fine-grained soil has 60% clay with LL 220%, PL 545%, and a natural water content of 6%. Astandard Proctor test was carried out in the laboratory and the following data were recordedDiameter of mold = 101.40 mm Height of mold = 116.70 mm Mass of mold = 4196.50 gram Specific gravity, Gs = 2.69 a) What field equipment would you specify to compact the soil in the field, and why?b) How would you check that the specified dry unit weight and water content are achievedin the field?
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 ?
