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
