A road embankment needs 130,000 cu.m. to be completed. DPWH requires 96% compaction and the contractor is to provide soil from a borrow site. The optimum moisture content is 17% and the maximum dry density is 19.20 kN/m3.
How much borrowed soil (in m3) is required if the moisture content of the borrowed material is 14% and the moist unit weight of the borrow is 17 kN/m3.
Step by step
Solved in 2 steps
- An embankment for a highway 30 m wide and 1.3 m in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content, w, of the sandy soil in the borrow pit is 17% and its void ratio, e, is 0.75. The specification requires the embankment be compacted to a dry unit weight of 19 kN/m^3. Determine, for 3 km length of embankment. Assume Gs = 2.7 a) Compute the volume (m³) of borrow material required b) solve the cost of fill if the earth fill from borrow site costs Pho 150/m³ c) calculate the volume (m³) of borrow material required is the specification required a void ratio of 0.20In a fill section of a construction site, 1500 m3 of moist compacted soils is required. 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?A new construction site requires 1500 m3 of moist compacted soils. The design specification of the fill material specifies the following: Water Content 15% Unit weight of the compacted soil to be 18.5 kN/m3 Soil from borrow site has the following specification: Water Content 12% Unit weight of the borrow material: 17.5 kN/m3 Soil Specific Gravity: 2.6 How much (in cubic meters) of the borrow material is required to fill the construction fill section?
- 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?Soil has been compacted in an embankment at a bulk density of 2.15 Mg/m³ and a water content of 12%. The value of Gs is 2.65. Calculate the dry density, void ratio, degree of saturation, and volume of air.An embankment is to be constructed for a certain project, as such filling materials are required to be excavated from borrow pits. The moist unit weight of the undisturbed soil is 20 kN/m3 and its water content is 10%. In order to build a 5 m high embankment with top width 2 m and side slopes 1:1, estimate the quantity of earth required to be excavated per meter length of embankment. The dry unit weight required in the embankment is 17 kN/m3 with a moisture content of 12%. Assume the specific gravity of solids as 2.65.
- A 200,000 cu. m clay embankment is to be constructed at an optimum water content of 15%. It is expected that 95% saturation will be attained. Calculate the volume of the soil that will be needed if the void ratio of the fill material is 1.0.Assume that an area is underlain by a stratum of compressible soil 5.3 m thick. The weight of the proposed structure, say an earth embankment for a new highway, will result in an increase of 28.2 kPa pressure to the compressible soil. The settlement under this loading would be 0.30 m. The 385 compressible layer is doubly drained, and the soil has a cv value of 0.4 m2/month. Calculations indicate that it would take approximately 22 months for the settlement to occur under the weight of the proposed embankment. How long would be required for a surcharge imposing a pressure of 56.4 kPa to cause the 0.30 m of settlement?An embankment for a highway 30 m wide and 1.5 m in compacted thickness is to be constructed from sandy soil trucked from a borrow pit. The water content of the sandy soil in a borrow pit is 15% and its void ratio is 0.69. The swell index is 1.2. The specification requires the embankment to be compacted to a dry unit weight of 18kN/m^3. Determine, for a 1-km length of embankment, the ff; (a) Dry unit weight of borrow pit material.(b) Volume of the finished embankment.(c) Volume of borrow pit soil required.
- The embankment for a highway 5097 ft long, 104 ft wide and 6 ft in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit. The water content of the sandy soil in the borrow pit is 6.748% and its porosity is 0.422. The specification requires the embankment be compacted to a dry unit weight of 122.874 lb/ft3. The specific gravity is 2.588. Determine the following: a. Total weight of the soil solids, kips. b. Total volume of the soil required from the borrow pit, ft3. c. Weight of water to be added per foot length of the embankment to reach 10% moisture content, lb.Round off answers to three decimal places.The embankment for a highway 5097 ft long, 104 ft wide and 6 ft in compacted thickness is to be constructed from a sandy soil trucked from a borrow pit.

Weight of water to be added per foot length of the embankment to reach 10% moisture content, lb.The excavated material has a wet unit weight of 1,510 kg/ cu metre and a dry unit weight of 1,398 cu metre. The material will be used to build an embankment. According to specification, the dry unit weight of the compacted material should be 1,826 kg/ cu metre, with a water content of 12%. The net section of the embankment is 86,000 cu metre. What is the moisture content of the excavated soil? How many cu metre of excavation will be required to construct the embankment? Do we need to add water or not? If yes, what’s the volume of added water?
