The proposed grading at a project site will consist of 25,100 m³ of cut and 23,300 m³ of fill and will be a balanced earthwork job. The cut area has an average moisture content of 8.3%. The fill will be compacted to an average relative compaction of 93% based on a maximum dry unit weight of 18.3 kN/m³ and an optimum moisture content of 12.9% obtained from the modified Proctor test. Compute the volume of water in kiloliters that will be required to bring these soils to the optimum moisture content.

Your company has won a contract to provide and compact the fill material for an earth levee, with the dimensions shown below. 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. When the soil is excavated and loaded on to your trucks, the voids ratio of the material is e = 1.47. Your trucks can haul 15 cubic yards of material per trip. (26) Determine the volume of fill required for the levee; (27) Determine the volume required from the borrow pit; (28) Determine the required number of truckloads. 40* 20 -20 20 450 60' 3:1

A compacted fill, currently under construction, will support a proposed supermarket. One of the field density tests in this fill gave a unit weight of 121 lb/ft³ and a moisture content of 12.5%. A series of modified Proctor tests have also been performed on the fill soils per ASTM D1557, and they gave a maximum dry unit weight of 117 lb/ft³ and an optimum moisture content of 13.0%. Compute the relative compaction based on the modified Proctor test and determine whether or not it satisfies the normal compaction specification for such a project.

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.

A 2m high sandy fill material was placed loosely at a relative density of 47%. Laboratory studies indicated that the maximum and minimum void ratios of the fill material are 0.92 and 0.53, respectively. Construction specifications required that the fill be compacted to a relative density of 80%. If Gs = 2.65 determinea) the dry unit weight of the fill before and after compactionb) the final height of the fill after compaction

A 3-m high sandy fill material was placed loosely at a relative density of 55%. Laboratory studies indicated that the maximum and minimunm void ratios of the fill material are 0.94 and 0.66, respectively. Construction specifications re- quired that the fill be compacted to a relative density of 85%. If G, = 2.65, determine: Dry unit weight of the fill before and after compaction Final height of the fill after compaction a. b. 202

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. How many operational hours would be required to dredge sufficient soil for the embankment? what would be the volume of the excavation at the bottom of the canal? c. A…

Standard proctor compaction test results on a sandy clay (35% sand, 55% clay, and 10% silt), taken from a borrow pit, are given in the following table. The sandy clay in the borrow pit has a porosity of 65% and a water content of 5.2%. A highway embankment is to be constructed using this soil.   (a) Specify the compaction (dry unit weight and water content) to be achieved in the field. Justify your specification. (b) How many cubic meters of borrow pit soil are needed for 1 cubic meter of highway fill?   (c) How much water per unit volume is required to meet the specification?   (d) How many truckloads of soil will be required for a 100,000 m3 highway embankment? Each truck has a load capacity of 22.5 m3 and regulations required a maximum load capacity of 90%.   (e) Determine the cost for 100,000 m3 of compacted soil based on the following: Purchase and load borrow pit material at site, haul 2 km round-trip, and spread with 200 HP dozer = $15/m3; extra mileage charge for each km =…

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 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…
