Geogrid stands for a geosynthetic materials mostly employed as a type of reinforcement material in construction works. It is mainly utilized in the soil reinforcement or in the reinforcement of retaining walls.
It is gaining popularity due to several factors like it is strong in tension and contains a greater strength to disperse or reallocate the load across a bigger area. This characteristic is beneficial for the pavement construction to enhance its durability and strength.
Functions and Working of Geogrids
The purpose of geogrid is to retain or obtain the aggregates collectively. By using this method of interlacing the aggregates facilitate in an earthwork that is settled mechanically. The apertures in geogrid allows to interlace the aggregates or the soil arranged over them.
It offers the following functional mechanisms while being used for pavement construction:-
Tension Membrane Effect
This mechanism depends on the perception of vertical stress distribution. This vertical stress originates from the deformed shape of the membrane. This mechanism was treated as the primary mechanism in earlier stage. But in due course it is proven that the lateral restraining mechanism is the most important factor that should be considered.
Enhancement of Bearing Strength
As soon as Geogrid is set up in pavement, the lateral movement of the aggregate is decreased significantly. It leads to reduction of stresses; that if prevails would have shifted to the subgrade.
The Geogrid layer contains adequate frictional resistance that counters subgrade lateral movement. Thus, this mechanism makes the bearing strength of the layer greater. Cutback of external stresses signify that inward stresses are developed and due to this the bearing strength is raised.
Lateral Preventing Capacity
The stresses generated with the wheel loadings directing to the pavement lead to the lateral movement of the aggregates. Because of this the constancy of the entire pavement arrangement is impacted. The Geogrid functions a restraint against this lateral movement.
