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.

Please write the solution on a piece of paper, hoping for your kind consideration
In an experiment of determining the porosity and specific gravity of solids of a soil, a soil is dug out from the ground, weighed, then oven dried, and then saturated with water. The weight of the soil taken from the test hole is 1346 grams. It was then oven dried and weighed 1076 grams. After saturating it with water, it weighed 1462 grams. The volume of the test hole was then measured and found to be 792 cc. Determine the void ratio (in percentage) of the soil sample.
The Unit weight of a soil sample is 19. 6 Kilo-Newton per cubic meter. Calculate the following: a. Convert the unit in pcf (Pounds per cubic feet). b. Density in pcf (pounds per cubic feet). c. If the soil has a mass of 3 slugs, determine the volume of the soil in cubic feet. Show complete solution.
2.24 A sample of soil plus container weighs 397.6 g when the initial water content is 6.3%. The container weighs 258.7 g. How much water needs to be added to the original specimen if the water content is to be increased by 3.4%? (After U.S. Dept. of Interior, 1990.)
The porosity of a silty sand soil sample is found to be 0.309. Its initial weight is 274.471 grams, and after oven drying for 24 hours, it reduces to 244.321 grams. If the density of the soil solids is 2581 kg/m3, determine the following:Bulk unit weight, Volume of voids, Volume of water to be added/evaporated per cubic meter of soil to attain 50% degree of saturation
