GEOTECHNICAL ENGINEERING: The Undisturbed soil at a given borrow pit is found to have the following parameters. 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.

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
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.
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 ?
A borrow pit’s soil is being used as earth fill at a construction project. The in-place dry density of the borrow pit soil is known to be 1,825 kg/m3. The job contract requires the soil at the construction site to be compacted to adry density of 1,975 kg/m3. The project requires 12,000 m3 of compacted soil fill. What volume of soil will the earthmoving contractor be required to obtain from the borrow pit to provide the necessary volume of compacted fill?
• Problem 2. You are tasked with constructing a rolled fill with a total volume of 35,000 m^3. The borrow that you will use has soil with w=15%, bulk unit weight= 19.1 kN/m^3; Gs=2.75. The trucks that will move the soil have a capacity of 4.80 m^3. The compaction specification of your construction project are w=18% and dry unit weight=17.3 kN/m^3. a) Assuming that each load is at full capacity, how many truckloads are required to construct the fill? b) What should be the volume of the pit that remains in the borrow area, after all the material required from the fill has been removed? c) How many liters of water will have to be added per truck load, assuming that the moisture lost by evaporation, hauling, and excavation is negligible?
1. Why will bulk density vary between soils but it is valid to use a constant value for particle density (2.65 g cm-3)?
QUESTION 1: PHASE RELATIONS a. 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. b. A soil to be used in the construction of an embankment is obtained by hydraulic dredging of a nearby canal. The embankment is to be: placed at a dry density of 1.72 t/m³ and will have a finished volume of 20,000 m³. The in situ saturated density of the soil at the bottom of the canal is 1.64 t/m³. The effluent from the dredging operation, having a density of 1.43 t/m³, is pumped to the embankment site at the rate of 600 L per minute. The specific gravity of the soil grains is 2.70. i. ii.

The in-situ moisture content of a soil is 18% and its moist unit weight is 105pcf. The specific gravity of the solids is 2.75. The soil is to be excavated and transported to a construction site and then compacted to a minimum dry weight of 103.5pcf at a moisture content of 20% How many cubic yards are needed to produce 10000 cubic yard? How many truckloads are needed to transport the excavated soil if each truck can carry 20tons? Assume that the excavated soil has a swelling factor of 15%.

The levee fill is a silty clay soil to be compacted to at least 95% of maximum Standard Proctor of ya = 106 pcf at an OMC of 18%. Your borrow pit has a silty clay with an in-situ moist density of 112.1 pcf at 18%, and a G, = 2.68.
