Geogrids play a very important role in road construction, mainly used to reinforce roadbeds and extend life time of the roads. Following is a detailed introduction.
1. Geogrids are mainly used to reinforce soft grounds, roadbeds and abutments, to protect side slopes, in reinforced soil projects and other civil engineering applications including wing walls, retaining walls, etc.
2. Geogrids can protect the railway on soft grounds from settlement and damage.
3. Geogrids can be used in the water?conservancy engineerings including risk-removal and reinforcement of reservoirs, dams, canals and reclaiming?lands.
4. Geogrids in the bases of airports can improve the bearing capacity of the runways and ensure the safety.
5. Geogrids can also be used in other fields such as mining industry, metallurgy industry and civil engineering including landfills, power stations, ash dams, landscapes and fences.
6. Geogrids can be used to reinforce soft grounds and improve the bearing capacity of the bases.
Geogrids are used to reinforce all kinds of dams, roadbeds, side slopes, tunnel walls, and permanent base of large airport, parking lot, wharf, freight yard, etc. They can effectively block the seismic force transmission and improve the earthquake severity, strength and stability of embankment. The applications of geogrids are expected to reduce all kinds of common embankment diseases in high-intensity earthquake region and improve the earth resistance and hazard reduction ability of roads. But the existing earthquake-resistant design codes for highway and railway have not made any specification for reinforcement of embankment to increase seismic resistance using geogrid.
Geogrids are 2D latticed grids or three-dimensional screen grids made from high-molecular polymers like polypropylene and PVC (polyvinyl chloride) by thermoforming or mould pressing. They are applied in the field of civil engineering. Geogrid are important geosynthetics. They are special in performance and function compared with other geosynthetics. Geogrids are often used as tendon materials of reinforced soil structures or of other composite materials. Geogrids can be divided into four categories, namely plastic geogrid, steel geogrid, glass fiber geogrid and polyester warp knitting dacron geogrid.
