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.
Q5-A proposed earth dam requires 7500 m³ of compacted soil with relative density of 94%, maximum void ratio of 0.73, minimum void ratio of 0.4 and specific gravity (Gs)= 2.67. Two borrow pits are available as described in the following table. Choose the best borrow pit with a minimum cost. Borrow Pit A B Degree of saturation % 82 100 Moisture content % 18.43 24.34 Cost ($/m³) 10 5
Read the question carefully and give me both a&b right solutions. A proctor compaction test in the laboratory on a borrow pit soil gives maximum unit weight of 19 kN/m3 and optimum water content of 11.5%. The bulk unit weight and water content of the soil in the borrow pit are 17.2 kN/m3 and 8.2%, respectively. A highway fill is to be constructed using this soil. The specifications require the fill to be compacted to 95% Proctor compaction. (a) What is the additional weight of water per unit volume required to bring the moisture content to the optimum value to achieve 95% Proctor compaction? (b) How many truckloads of borrow pit soil will be required for a 100,000 m3 highway embankment - assuming each truck has a capacity of 10 m3 ?
4. 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.

PTOR The in-situ density of an embankment, compacted at a water content of 12% was determined with the help of a core cutter. The empty mass of the cutter was 1286 g and the cutter full of soil had a mass of 3195 g, the volume of the cutter being 1000 cm³. Determine the bulk density, dry density and the degree of saturation of the embankment. If the embankment becomes fully saturated during rains, what would be its water content and saturated T h unit weight? Assume no volume change in soil on saturation. Take the specific gravity of the soil as 2.70. ition:
