16.65 kN/m³ at an Optimum Moisture Content (OMC) of 18%. Your
borrow pit has a silty clay with an in-situ moist density of
17.60 kN/m³ 18% moisture content, and Gs = 2.68. When the
soil is excavated and loaded on to your trucks, the void ratio of
material is e= 1.47. Your trucks can haul 11.5 m³ of materials per
trip.
a. Determine the volume of fill required for the levee.
b. Determine the volume required from the borrow pit.
c. Determine the required number of trucks.

Embankment is to be built with 15 km length of proposed road with 2 m height of road embankment. The cross sectional area of embankment and distance of borrow pit from embankment are 30 m² and 10 km respectively. Soil is to be compacted to 97 % of the max dry density. Information given as follows: (a) Results from laboratory compaction test: Max dry density-1.80 Mg/m³ Optimum water content=12% (b) Borrow material: Dry density-1.70 Mg/m² Water content-8% Calculate volume of additional water required for the entire volume of the embankment Final answer should be = 27, 486 m³

Number of Blows 6 5 12 6 18 7 Which of the following is incorrect regarding the Soil Classification Systems?a. The AASHTO Soil Classification System is commonly used in highway design and construction b. In the USCS, SP stands for Poorly Graded Sandc. Both AASHTO and USCS, percent passing #200 sieve is a crucial piece of informationd. Percent passing #4 sieve is required in order to use the AASHTO system
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.
