Soil Stabilization Using Mechanically Stabilised Layer with Geogrid
Importance of high radial stiffness ratio and not radial stiffness alone
Benefits of mechanical stabilisation
Fitness for intended use
Stabilisation
Lateral restraint
Interlock
Confinement
Radial stiffness
Reinforcement
Friction
Strength important
Anchorage
Tensioned membrane
Protection of subgrade
Thickness reduction vs increassed life
Interlock confinement & lateral restraint
Load is perpendicular to geogrid
Low deformation response
Importance to have equal stiffness in the spoke of a bicycle wheel to maintain its geometry
Importance to have strong hub to spoke connection to ensure spoke stability
