Hill Roads - Design & Construction - Articles

The degree of stability of hill slopes depends on types of rock, degree of strata inclination or dip, occurrence of clay seams, the hardness of the rocks and presence of ground water. When locating the route an engineer must study the details of geological conditions of that area and follow stable hill slopes where no ground water, landslides ...

Soil Washing | Geoengineer.org

Jan 29, 2013 · Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and ...
