Soil compaction field test
Webdetecting soil problems such as compaction and crusting. Typical infiltration rate for a clay soil is 0.04 to 0.2 inches/hr. Figure 5. An aluminum ring is driven into the soil. Saran wrap is placed over the soil surface and 1” of water ponded on top. The saran wrap is pulled away to allow the water to start infiltrating (A), which WebDownload as PDF. Soil Compaction is the process of increasing the unit wt of soil by forcing the soil solids into a. dense state and reducing the air voids. Compaction leads to increase in shear strength and helps improve the stability and bearing capacity of soil. It also reduces the compressibility and permeability of soil.
