2. Soil sealing - Wikipedia

   en.wikipedia.org/wiki/Soil_sealing

   Soil sealing or soil surface sealing is the loss of soil resources due to the covering of land for housing, roads or other construction work. [1] Covering or replacing the topsoil with impervious materials like asphalt and cement as a result of urban development and infrastructure construction paired with compaction of the underlying soil layers results in the mostly irreversible loss of ...

3. Infiltration (hydrology) - Wikipedia

   en.wikipedia.org/wiki/Infiltration_(hydrology)

   On sandy loam soils, the infiltration rate under a litter cover can be nine times higher than on bare surfaces. The low rate of infiltration in bare areas is due mostly to the presence of a soil crust or surface seal. Infiltration through the base of a tuft is rapid and the tufts funnel water toward their own roots. [6]

4. Soil consolidation - Wikipedia

   en.wikipedia.org/wiki/Soil_consolidation

   The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...

5. Physical properties of soil - Wikipedia

   en.wikipedia.org/wiki/Physical_properties_of_soil

   Higher moisture content or increased electrolyte concentration can lower resistivity and increase conductivity, thereby increasing the rate of corrosion. [ 123 ] [ 124 ] Soil resistivity values typically range from about 1 to 100000 Ω ·m, extreme values being for saline soils and dry soils overlaying crystalline rocks, respectively.

6. Compressed earth block - Wikipedia

   en.wikipedia.org/wiki/Compressed_earth_block

   Transport cost: Suitable soils are often available at or near the construction site. Strengths might exceed the ASTM standard for concrete blocks (1900 psi) in some instances. In India, the observed compressive strength and flexural strength of CSEB at 28 days of aging with 9% cement stabilization has been observed to be 3.2 MPa (464 psi) and 1 ...

7. Earthworks (engineering) - Wikipedia

   en.wikipedia.org/wiki/Earthworks_(engineering)

   In that case, earthwork software is principally used to calculate cut and fill volumes which are then used for producing material and time estimates. Most products offer additional functionality such as the ability to takeoff terrain elevation from plans (using contour lines and spot heights ); produce shaded cut and fill maps; produce cross ...

9. Soil compaction - Wikipedia

   en.wikipedia.org/wiki/Soil_compaction

   In order to determine if the natural soil will support the first fill layers, an area can be proofrolled. Proofrolling consists of utilizing a piece of heavy construction equipment to roll across the fill site and watching for deflections to be revealed. These areas will be indicated by the development of rutting, pumping, or ground weaving. [5]
