3 for the road surface, so that the grid and pavement materials are mixed together, can effectively disperse the load transfer, to prevent road cracks;4 can withstand a certain impact load;5 can withstand large alternating load;6 shorten the construction cycle;7 in harsh environmental conditions, can also be constructed;8 can prevent frost caused by surface subsidence and crack;9 can reduce the amount of pavement material;
Geogrid effect1 used for roadbed reinforcement, so that the granular filler and mesh together locked together to form a stable plane, to prevent the collapse of the filler, and the vertical load can be dispersed, the geographical conditions of poor areas can be used multi-layer reinforcement;2 in the embankment and embankment fill can increase its stability, reduce the area;
Geogrid is a kind of main geosynthetics, which has unique properties and effects compared with other geosynthetics. Geogrid is often used as reinforcement of reinforced soil structure or composite material. Geogrid is divided into four categories: plastic geogrid, steel plastic geogrid, fiberglass geogrid and fiberglass polyester geogrid.
