The core of an earth dam is to be compacted on the wet side of optimum so as to ensure low permeability and flexibility (a nonbrittle stress-strain relationship). You have the choice of using a sheepsfoot roller or a smooth-wheel roller to compact the soil. To reduce potential shrinkage of the dam core, which is the best piece of equipment to use? If the soil were to be compacted dry of optimum, would it matter?

In natural state, a soil weighs 3500 lb/cy. The same soil has a load factor of 0.83. a. What is the unit weight of the soil in its loose state? b. A contractor has seven (7) Caterpillar 725 articulating trucks available to haul this same soil to a project that requires 55,000 ccy of the soil. In the compacted state, the soil weighs 4300 lb/cy. Each Caterpillar 725 has a maximum haul capacity of 17 lcy. Currently the project schedule only accounts for each truck hauling no more than 550 loads to the site. Based on the maximum capacity of the Caterpillar 725, can this schedule requirement be met?
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.

Backhoe excavator worked for 45 hours to excavate and stock the required earth volume to be loaded by apayloader to a fleet of 5-dump trucks, which haul the earth to site where it is compacted on a shrinkage factorof 20%. Each truck has a total cycle time of 15 minutes, assuming it does not have to wait in line to be loaded.The earth has a percent swell of 25%. The job requires a compacted volume of 30,000 m 3 done by a road grader,roller compactor and water tanker in 70 hours. Calculate the direct equipment total cost spent considering thefollowing? a. Payloader capacity – 220 m 3 (bank volume) of common earth per hour.b. Dump trucks capacity – 20 m 3 (loose volume) each unitc. Payloader rental rate – ₱650/hourd.

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?

A manufacturing plant was constructed on a silty soil 3 m. thick which is underlain by sand and gravel. After many years, after all, water wells and the rate of pumping being made in the area, the water table was lowered from 3 m. below the ground surface to 6 m. below the ground surface. The unit weight of the soil above the water table is 15.74 kN/m3 and below the water table is 18.88 kN/m3. The dry unit weight of the soil below the silty layer when the water table dropped down is 16.21 kN/m3. The compression index is 0.32 and the void ratio of the soil before the water table was lowered was 0.60. The building floor load is 24 kPa.a) Compute the final stress at A.
