= Construction of an embankment needs 400,000 yd3 of fill. The fill should be compacted to at least 88% of the standard Proctor maximum dry density obtained in the lab, which is gammad_d,max : 128 pcf, but the contractor plans to exceed that by 2% to ensure passing quality control. The fill may be obtained from two companies (A and B) with the following profiles. Company A Distance from borrow pit to embankment: 25 miles Cost of haul ($/yd3-mile): 0.50 Cost of fill material ($/yd3): 1.50 Borrow soil moisture content: 16% Specific gravity of solids: 2.70 Degree of saturation: 70% Company B Distance from borrow pit to embankment: 30 miles Cost of haul ($/yd3-mile): 0.40 Cost of fill material ($/yd3): 1.40 Borrow soil moisture content: 18% Specific gravity of solids: 2.65 Degree of saturation: 58% The total cost of haulage by company A (million $) The total cost of haulage by company B (million $) The relative compaction, CR, should account for the contractor's plan to exceed the minimum…

A soil deposit to be used for construction of an earth embankment has an average dry density of 1620 kg/m³. If the compacted embankment is to have an average dry density of 1720 kg/m³ determine the volume of soil to be excavated for 1000 cu.m. of embankment. The water content of the soil in the borrow pit is 10%.
Problem 2: The above borrow pit soil has a natural bulk unit weight of 17.5 kN/m² and water content of 8.5%. An embankment is to be constructed using this soil and the specification require the fill to be compacted to 96% of the above proctor compaction. Determine the cost for 50,000 m³ of the embankment considering the following: a) The distance between the borrow pit and the embankment is 55 km b) The cost of transporting 1 m³ of the borrow pit soil to the site is 16 OMR/km. c) The cost of compaction is 8 OMR/m³.
• Problem 2. You are tasked with constructing a rolled fill with a total volume of 35,000 m^3. The borrow that you will use has soil with w=15%, bulk unit weight= 19.1 kN/m^3; Gs=2.75. The trucks that will move the soil have a capacity of 4.80 m^3. The compaction specification of your construction project are w=18% and dry unit weight=17.3 kN/m^3. a) Assuming that each load is at full capacity, how many truckloads are required to construct the fill? b) What should be the volume of the pit that remains in the borrow area, after all the material required from the fill has been removed? c) How many liters of water will have to be added per truck load, assuming that the moisture lost by evaporation, hauling, and excavation is negligible?
