Correct Answer - Option 4 : Stiffness
Concept:
Geosynthetics:
Geosynthetics are man-made materials used to improve soil conditions.
They include the functions of separation, filtration, reinforcement, stiffening, drainage, barrier, and protection of roadways.
The important physical properties of Geosynthetic are,
- Thickness
- Unit Weight
- Stiffness or flexural stiffness or flexural rigidity
- Specific gravity
The most useful geosynthetic physical property which is closely related to engineering performance is
Stiffness.
