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.

As part of a quality controlprogram, the field inspection engineer conducted a sand cone test to determine the field density. The following data were recorded using the sand cone method. • Calibrated dry density of Ottawa sand = 1667 ??/?3• Mass of Ottawa sand to fill the cone = 0.117 kg• Mass of jar + cone + sand (before use) = 6.1 kg• Mass of jar + cone + sand (after use) = 2.83 kg• Mass of moist soil from hole = 3.35 kg• Moisture content of moist soil = 16.1%a. Determine the dry unit weight of compaction in the field. (ANS: 14.97kn/m3) PLS ANSWER NUMBER 2 WITH COMPLETE SOLUTION 2.

If after completing a Sieve Analysis lab, I notice that the stack of sieves was not arranged in the order of progressively smaller openings from top to bottom. I noticed that two sieves in the middle of the stack had their order reversed; the sieve with a tinier opening was on top of a sieve with a larger opening. How will this mistake affect my results and can my results still be used for obtaining the soil’s grain-size distribution curve? Please help me in figuring this out, I believe that it will affect the soil’s grain-size distribution curve's accuracy, but I am not sure why or in what capacity.
