Geogrids are a major geosynthetic material with unique properties and efficacy compared to other geosynthetics. Geogrids are commonly used as reinforcement for soil structures or composite materials. Geogrids are divided into several categories and the materials are classified into glass fibre grids, steel plastic grids etc., which are used in different places on roads and roadbeds respectively. The applications of geogrids. 

1. Used for roadbed reinforcement, so that granular fill and grating are locked together to form a stable plane, preventing the fill from sinking and dispersing the vertical load. In geographically disadvantaged areas, multiple layers of reinforcement can be used.

2. Lining embankments and road base fills increases their stability and reduces the footprint; for pavement reinforcement, mixing the grid with the pavement material effectively disperses and transmits the load and prevents cracking of the pavement.

3. geogrids can withstand certain impact loads; they can withstand greater AC loads

4. it shortens the construction period of a project. it can also be constructed under harsh environmental conditions.

5. it prevents crumbling and cracking of the pavement due to frost; it reduces the amount of surfacing material; it speeds up construction
