A road filling with 100% relative compaction will be made. The final volume of this filling in 100% compressed state will be 15.000 m3, maximum dry unit weight of 2 t / m3 and optimum water content of 0.15. For this road fill, the water content of the land is 0.14. a- How many tons of ground should be transported from the land for road filling? b- How much water is needed for 100% compression?

5. Estimate the cost of compacting 3700 CCM using a roller compactor based on the following information: The number of passes required = 10 Width compacted per pass = 2m Compactor speed = 7km/h Compacted lift thickness = 0.3m Job efficiency = 55min/h Cost per hour = $150
Suppose that you are a Project Engineer on a Dam project. The volume of soil required at the dame site is Vd=100,000m3. The final void ratio (ed) is 0.80. Your boss, the Project Manager delegates to you the important decision of buying the earth fill from one of three suppliers. • Supplier X sells fill at OMR. 0.200/m3 with e = 0.90• Supplier Y sells fill at OMR. 0.120/m3 with e = 2.00• Supplier Z sells fill at OMR. 0.150/m3 with e = 1.60Evaluate and select the best supplier based on your knowledge about soil compaction.
Question 1: Earth whose in situ weight is 112 pcf, whose loose weight is 95 pcf and whose compacted weight is 120 pcf is placed in a fill at the rate of 250 cy/hr, measured as compacted earth. The thickness of the compacted layers is 6 inch. A compactor with a roller drum width of 84 inch is used to compact the material at a speed of 3.5 mph. Assume a 55 min hour operating efficiency. Determine the number of rollers required to provide the necessary compaction rate if eight drum passes are specified for each layer of earth. O 1 Roller O 3 Rollers O O Roller O 2 Rollers
You have been hired as a project Engineer for a development company in Namugongo to build 610 housing units. Since the original ground is low, you need fill material to raise the ground level. Your estimated fill requirements are 700,000m3 with a void ratio of 0.46. the insitu material at the borrow pit has a void ratio of 0.39 where as the material dumped in trucks has a void ration of 0.71. How many trucks will you need, if each truck carries 10m3? i will need all the work outs in full and well explained
9- The bulk unit weight and water content of a soil at a borrow pit are 17.2 kN/ml and 8.2% respectively. A highway fill is being constructed using the soil from this borrow at a dry unit weight of 18.05 kN/m³ • Find the volume of the borrow pit that would make one cubic meter of the finished highway fill. Answer: 1.136 m3
Backhoe excavator worked for 45 hours to excavate and stock the required earth volume to be loaded by apayloader to a fleet of 5-dump trucks, which haul the earth to site where it is compacted on a shrinkage factorof 20%. Each truck has a total cycle time of 15 minutes, assuming it does not have to wait in line to be loaded.The earth has a percent swell of 25%. The job requires a compacted volume of 30,000 m 3 done by a road grader,roller compactor and water tanker in 70 hours. Calculate the direct equipment total cost spent considering thefollowing? a. Payloader capacity – 220 m 3 (bank volume) of common earth per hour.b. Dump trucks capacity – 20 m 3 (loose volume) each unitc. Payloader rental rate – ₱650/hourd. Dump truck rental rate – ₱180/houre. Backhoe rental rate – ₱800/hourf. Road grader rental rate = ₱ 550/hrg. Roller compactor rental rate – ₱750/hourh. Water tanker rental rate – ₱ 120/hr

Your company has won a contract to provide and compact the fill material for an earth levee (an embankment built to prevent overflow of a river), with the dimensions shown below. The levee fill is a silty clay soil to be compacted to atleast 95.1% of maximum standard Proctor of dry unit weight= 109lb/cu.ft at an OMC of 18.6%. Your borrow pit has a silty clay with an in-situ moist density of 112.6lb/cu.ft at 18.1% water content and a Gs = 2.679. When the soil is excavated and loaded on to your trucks, the void ratio of the material is e = 1.46. Your trucks can haul 401 cu.ft of material per trip. DETERMINE THE FF AND SHOW COMPELETE SOLUTION. ALL FINAL ANSWER WILL BE IN 3 DECIMAL PLACES. 1. Determine the volume of fill required for the levee in cu.ft 2. Determine the volume required from the borrow pit in cu.ft 3. Determine the required number of truck loads.
Problem 15: A proposed earth dam project will contain 7,000,000 m of compacted earth fill having a porosity of 0.4. There are three quarry pit sites nearby A, B and C. It is required to determine the most economical solution to this construction project based on the overall transport cost.

A recently completed fill was 6m thick and it's initial average void ratio was 1.0. The fill was loaded on the surface by constructing an embankment covering a large area of the fill.Measurement of the fill after 5 months indicated an average void ratio of 0.8 Estimate the compression of the fill after 5 months Estimate the total compression of the fill after one year assuming the average void ratio after one year
You have been hired as the Project Engineer for a development company in South Florida to build 610 housing units surrounding four lakes. Since the original ground is low, you will use the limestone excavated from the lake to fill the land in order to build roads and housing pads. Your estimated fill requirements are 700,000 m3, with a dry density equivalent to a voids ratio e= 0.46. The "in-situ" limestone extracted from the lakes has an e = 0.39, whereas the limestone dumped into the trucks has an e = 0.71. How many truckloads will you need, if each truck carries 10 m³?
An earthen embankment under construction has a total unit weight o f 99.9 lb/ft3 and a moisture content of 10 percent. Compute the quantity of water required to be added per 100 ft3 of earth to raise its moisture content to 14 percent at the same void ratio.
