Geotechnical characteristics and spectral properties of expansive soils biology essay

18. 18 The most important characteristic of the elastic behavior of soil is that the soil does not become permanently deformed. A. Plastic Limit (PL): The plastic limit (PL) is the moisture content at which a soil transitions from being in a semisolid state to a plastic state.

Soil plasticity& Elasticity : Soil plasticity is a property that enables the moist soil to change shape when some force is applied over it and to retain this shape even after the removal of the force from it. The plasticity of soil depends on the cohesion and adhesion of soil materials.

Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged. 12. 12 Cohesive soils include clayey silt, sandy clay, silty clay, clay and organic clay. It reflects the internal molecular attraction (binding capacity) which resists the rupture or shear (looseness) of a material.
