A 7000 meters long and 8 meters wide road is to be constructed in a remote region. Cut and fill are necessary where there is a poor subgrade soil. Four bulldozers excavated the poor subgrade soils. The dimensions of the excavated trench were 0.8 m deep by 10 meter wide and 3.5 kilometers long. The road will have 100 mm aggregate base and 50 mm of asphalt thickness.
A bulldozer displaced 115 m3\day, at a rate of 100 cedis per day. A laterite soil will be used in the fill operation. The fill operation will need a grader, a vibratory roller and a water truck for 20 days each at a cost of 130 cedis, 138 cedis and 68 cedis respectively. Daily labor rates for this excavation operation is a foreman, 30 cedis, five laborers, 15 cedis each. Truck driver, 21 Cedis and grade checker, 26 Cedis. Daily labor rates for the fill operations are the same as the excavation rates. One forman, ten laborers and a truck driver will be employed for the fill operations. Grading and asphalt laying will…

What exactly is meant by the term "compaction"?arrow_forwardPlease give a more detailed and correct solution with question C. The embankment for a highway 5097 ft long, 104 ft wide and 6 ft in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content of the sandy soil in the borrow pit is 6.748% and its porosity is 0.422. The specification requires the embankment be compacted to a dry unit weight of 122.874 lb/ft3. The specific gravity is 2.588. Determine the following: a. Total weight of the soil solids, kips. b. Total volume of the soil required from the borrow pit, ft3. c. Weight of water to be added per foot length of the embankment to reach 10% moisture content, lb.Round off answers to three decimal places.arrow_forwarda. A new road 18 m wide is under construction in flat terrain. Excavation to the sub-grade is taken to a depth of 600 mm below the ground surface. In order to stockpile the excavated material for later re-use you are required to stockpile the fill in two conical stockpiles. The excavated material is common fill and is dry with an angle of repose of 31° and a swell factor of 27%. Determine the size of each conical stockpile required for an excavation that is 40 m in length for the full width of the new road. b. If each stockpile is limited to a maximum height of 3m, what length of roadway should the excavated?arrow_forward
