Soil engineering for highway design

Soil engineering is a part of geotechnical engineering that deals with the characteristics of soil. It also helps to understand the behavior of the soil in different conditions. The basic concepts of soil are studied to check the strength, compressibility, and porosity of the soil. This makes soil engineering an important topic for civil engineering.

The excavated material has a wet unit weight of 1,510 kg/ cu metre and a dry unit weight of 1,398 cu metre. The material will be used to build an embankment. According to specification, the dry unit weight of the compacted material should be 1,826 kg/ cu metre, with a water content of 12%. The net section of the embankment is 86,000 cu metre. What is the moisture content of the excavated soil? How many cu metre of excavation will be required to construct the embankment? Do we need to add water or not? If yes, what’s the volume of added water?
In a fill section of a construction site, 1500 m3 of moist compacted soils is required. The design water content of the fill is 15%, and the design unit weight of the compacted soil is 18.5 kN/m3.

A subsurface exploration report shows that the average water content of a fine-grained soil in a proposed borrow area is 24.5% and that its average natural dry density is 83.3 pcf. This soil is to be placed in a compacted fill with a dry density specified at 95.5 pcf. -How many cubic yards of borrow will be required to produce 86,000 yd3 of fill? -What is the shrinkage factor for the borrow?
The following are given for a natural soil deposit: Moist unit weight, γ = 17.8 kN/m3 Moisture content, w = 14%; Gs = 2.7 This soil is to be excavated and transported to a construction site for use in a compacted fill. If the specification calls for the soil to be compacted at least to a dry unit weight of 18.4 kN/m3 at the same moisture content of 14%, how many cubic meters of soil from the excavation site are needed to produce 20,000m3 of compacted fill?
A new construction site requires 1500 m3 of moist compacted soils. The design specification of the fill material specifies the following: Water Content 15% Unit weight of the compacted soil to be 18.5 kN/m3 Soil from borrow site has the following specification: Water Content 12% Unit weight of the borrow material: 17.5 kN/m3 Soil Specific Gravity: 2.6 How much (in cubic meters) of the borrow material is required to fill the construction fill section?
The settlement analysis for a proposed structure indicates that 6.5 cm of settlement will occur in 3.4 years and that the ultimate total settlement will be about 22 cm. The analysis is based on the assumption that the compressible clay layer is drained at both its top and bottom surfaces. The owner decides to build a duplicate of the first structure nearby. During foundation investigations, it is discovered that the clay layer under the new building would be about 25% thicker than under the first structure. Otherwise, the properties of the clay are the same. Estimate for the new structure the ultimate total settlement (in cm.). Explain your answer.
A soil having a void ratio of 0.68 as it exists in a borrow pit is to be excavated and transported to a fill site where it will be compacted to a void ratio of 0.45. The volume of the fill required is 2500 m. Find the volume of the soil must be excavated from the borrow pit to furnish the required volume of fill. Calculate the total cost of the excavated material from the borrow pit, if the unit cost of material is 25 Dirhams per meter cube of fill.
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?
An approach road for a bridge needs 60000 m3 of soil compacted to a void ratio of 0.7. There are two borrow pits A and B from where the required soil can be taken and transported to the site. The borrow pit A has void ratio 0.85 and borrow pit B has void ratio 0.95. If the cost of excavation of soiland transportation is Rs. 20/10 m3for area A and Rs. 22/10 m3for area B, which of the borrow area is more economical? G=2.67
A proposed embankment till requires 5000 m of compacted soil. The void ratio of the compactedd till is specilied as 0.7. Four borroww pits are available as described in the following table. which lists the respective void ratios of the soil and the cost per cubic mcter for moving the soil to the proposed con- struction site. Make the necessary calculations to sclect the pit from which the soil should be bought to minimize the cost. Assume G, to be the same at all pits.
