The dam is approximately 300 feet long and averages around 120 feet tall. To find the compacted volume of the dam, youll need to calculate the volume using the below stations and end areas that your boss has provided you. The borrow material from the specification and core drills indicate the average moisture content of the soil to be mined is 15.17% moisture content in its natural state. The fill will be constructed in lifts of 6 inches in depth, loose measure and compacted to a dry weight of 118.52 lb./cf. The truck which you will be using to construct this dam is the Cat 772G Quarry Body (page 751 or 10-6 of the CAT Hand Book). The specification states that the moisture content of the compacted cubic yards will be 18.14%. Station End Area (sf) 0+00 1+00 1+50 2+00 3+00 16,000 21,600 25,800 20,600 16,000 You are to find the volume of bank cubic yards that will be needed to be mined, gallons of water needed, the gallons per compacted yards and the number of truck loads using the maximum capacity of each truck.
