A proposed earth embankment requires 60,000 cubic meters of soil. The soil will be compacted to a void ratio of 0.85. Two borrow pits designated as A and B are available near the site. The void ratio of the soil in each pit and the estimated cost per cubic meter for moving the soil to the site are as shown below. Pit Void Ratio Cost ($/m3) A 1.10 5.00 B 1.80 3.70 Which will have the lowest cost to move and be the most economical to use?
What should be the volume of the pit that remains in theborrow area after all the material required for the fill hasbeen removed?
If you’re required to excavate and remove 2200m³ of soil with a swell of 10% from site, your crewcan only remove 145m³ per day. How many days would you need to remove this material? (Round tothe nearest day)a. 22 daysb. 18 daysc. 14 daysd. 17 days
A proposed embankment fill requires 7500 m3 of compacted soil. The void ratio of thecompacted fill is specified as 0.7. Soil can be transported from one of the four borrowpits, as described in the following table. The void ratio, specific gravity of soil solids,and the cost per cubic meter for moving the soil to the proposed construction site areprovided in the table.a. Determine the volume of each borrow pit soil required to meet the specification ofthe embankment site.b. Make the necessary calculations to select the borrow pit which would be most costeffective.
A contractor excavates 10,000 m3 soil at moist unitweight of 17.5 kN/m3 and moisture content of 10%from a borrow pit and transports it to a project site.The project has an area of 20,000 m2 to be filled withthis compacted soil. If the required dry unit weightand moisture content of the compacted soil are 18.3kN/m3 and 12.5% (assume there is no soil loss duringtransportation and compaction), what is the thicknessof the compacted soil and how much water needs to beadded? If there are 2% dry soil loss and 3% moisture loss, what is the thickness of the compacted soil and how much water neeeds to be added to maintain the compaction at the required moisture content?

Q1. Answer the followinga) Convert 1700LCM of common earth to a volume in compacted measure (CCM). b) Calculate the volume of sand and gravel (in LCM) needed to fill a ditch that is 2km x 3m x 1.5m. The sand and gravel will be compacted.
The soil borrow material to be used to construct a highway embankment has a wet unit weight of 15.4 kN m3 ⁄ , a water content of 9%, and the specific gravity of the soil solids is 2.67. The specifications require that the soil be placed in the fill so that the dry unit weight is 17.9 kN m3 ⁄ and the water content be held to 20%.a. How many cubic meters of borrow are required to construct an embankment having a 612, 000-m3 net section volume?b. How many gallons of water must be added per cubic meter of borrow material assuming no loss by evaporation?c. If the compacted fill becomes saturated at constant volume, what will be the water content and unit weight?
A proposed embankment till requires 5000 m of compacted soil. The void ratio of the compactedd till is specilied as 0.7. Four borroww pits are available as described in the following table. which lists the respective void ratios of the soil and the cost per cubic mcter for moving the soil to the proposed con- struction site. Make the necessary calculations to sclect the pit from which the soil should be bought to minimize the cost. Assume G, to be the same at all pits.
A proposed embankment fill requires 5000 m3 of compacted soil. The void ratio of the compacted fill is 0.70. Three borrow pitsare available as shown in the table: )Determine the cost of acquiring soil from Pit C )Determine the Pit with least of hauling material )Determine the most economical pit.
From the given earthworks data shown, determine the total cost of earthworks if unit cost of haul is P 500 per on, unit cost of borrow is P 3,500 per cubic meter, and unit cost of excavation is P 1,000 per cubic meter. Free haul dist. mated to be 400 m. Assume shrinkage of 20 %.
In reply to figure-4.15-site-plan-for-review-question-11 I calculated the answer as cubic feet and converted to cubic yards, so 3606 cu ft cut and 1699.1 cu ft fill becomes 133.6 cubic yards cut, and 62.9 cubic yards fill. See graphic. Am i right? what is correct answer please? Regards R Goddard
