A 1 m-thick fill is compacted by a roller, and the thickness reduced by 90 mm. 94, what is the new void ratio after the compaction? Solution: Let’s consider a 1 m2 area in plan. Find the volume of soil grains Vs. 0 m3 → e = e=? 5%. The soil from this borrow will be used to construct a compacted fill with a finished volume of 42,000 m3. 50 m3. 5 kN. In the construction process, the trucks dump the soil at the site, then the soil is spread and broken up. Water is then sprinkled to bring the water content to 15%.

8% . . 625 emax − emin J. , same order of dimensions in the three orthogonal directions), clay particles (or grains) are generally two-dimensional or sometimes one-dimensional. They look like flakes or needles. Their surfaces are electrically charged due to a charge imbalance between the cations and anions in their atomic structures. Since the particles are flakey and finer than 2 mm, they have larger specific surfaces (surface area per unit mass) than do silts, sands, or gravels. Large specific surfaces and the electric charges make the clays sticky when wet, and make them cohesive, which makes them behave differently than noncohesive soils do, such as sands and gravels.

The same test was repeated, but with a larger compactive effort (Test 2). The water contents and wet masses of the samples from the two tests are given. Water content (%) Wet mass (g) Test 1 Test 2 11 1867 1937 13 1956 2034 15 2044 2108 17 2106 2118 19 2090 2097 21 2036 2055 Compute the dry densities and plot them against the water content for both tests. Solution: ​The volume of the compacted sample is 1000 cm3. The dry density can be determined using the equation rm 5 rd(1 1 w) from Chapter 2 under Worked Example 1.
