The water content is 15%, the void ratio is 0.60 and the specific gravity of the solids is 2.70.The soil from this borrow pit is to be used to construct a rolled fill having a finished volume of 50,000 yd3. The soil is excavated by means of a shovel and dumped on trucks. When loaded to capacity these trucks are found to contain, on average, a net weight of wet soil equal to 13,000 lbs.In the construction process, the trucks dump their load on the fill, the material is spread and broken up, after which a sprinkler adds water until the water content is equal to 18%. The soil and water are thoroughly mixed by means of dicers (or other similar equipment) and then compacted until the dry unit weight γd=110 lbs/ft3 Helpful Conversions (3ft=1yd), (γw=62.4 lbs/ft3), (7.48gal/1ft3) a) Assuming that each load is a capacity load, how many truck loads are required to construct the fill?b) What is the volume in…A proposed embankment fill required 8000 m3 of compacted soil. The void ratio of the compacted fill is specified to be 0.6. Four available borrow pits are shown below along with the void ratios of the soil and the cost per cubic meter for moving the soil to the proposed construction site. Make the necessary calculations to select the pit from which the soil should be brought to minimize the cost.

The design water content of the fill is 15%, and the design unit weight of the compacted soil is 18.5 kN/m3. Necessary soil is brought from a borrow site, with the soil having 12% natural water content, 17.5 kN/m3 wet unit weight, and Gs = 2.65. How much (in cubic meters) of the borrow material is required to fill the construction fill section? And how heavy is it?In a fill section of a construction site, 1600 m³ of moist compacted soils are required. The design water content of the fill is 14.5%, and the design unit weight of the compacted soil is 17.8 kN/m³. Necessary soil is brought from a borrow site, with the soil having 11.5% natural water content, 17.2 kN/m³ wet unit weight, and G, = 2.64. How much (in cubic meters) of the borrow material is required to fill the construction fill section? And how heavy is it?
- A soil having a void ratio of 0.68 as it exists in a borrow pit is to be excavated and transported to a fill site where it will be compacted to a void ratio of 0.45. The volume of the fill required is 2500 m. Find the volume of the soil must be excavated from the borrow pit to furnish the required volume of fill. Calculate the total cost of the excavated material from the borrow pit, if the unit cost of material is 25 Dirhams per meter cube of fill.Q2/ For proposed Earth Dam fill, the soil will be compact to (95%) of standard proctor dry density. The test of borrow area indicate that (ydmax = 18 kN/m3) at optimum moisture content (11%). The soil of borrow area at natural condition has (e = 0.65) and (Gs = 2.68). Determine the minimum volume ofborrowrequired to make (600,000 m3 ) of acceptable compacted fill.The following are given for a natural soil deposit: Moist unit weight, γ = 17.8 kN/m3 Moisture content, w = 14%; Gs = 2.7 This soil is to be excavated and transported to a construction site for use in a compacted fill. If the specification calls for the soil to be compacted at least to a dry unit weight of 18.4 kN/m3 at the same moisture content of 14%, how many cubic meters of soil from the excavation site are needed to produce 20,000m3 of compacted fill?
- Specifications require that a fill using borrow soil to be compacted at 95% of its standard proctor maximum dry density. Tests indicate that this maxi-mum is 19.5 kilo Newtons per cubic meter with 12 % moisture. The borrow material has a void ratio of 0.60. Compute the minimum dry and wet unit weight of the compacted soil, compute also the minimum volume of borrow material required to fill 1 cubic meter when compacted. Assume a logical value of Gs with at least 4 significant figures.the following are given for natural soil deposite; moist unit weight =17.8KN/m3, moisture content=14% this soil is to be excavated to a construction site for use in compacted fill. if the specification calla for the soil to be compacted to minimum dry unit weight of 18.8kn/m3 at the same moisture content of w=14% how many cubic meters of soil from the excavation site are needed to produce 20000m3 of compacted fillThe in situ moisture content of a soil is 18% and the moist unit weight is 16.5 kN/m3.The specific gravity of soil solids is 2.75.
