As we all know, geogrid is a new type of road construction material. It has the function of strengthening the roadbed and pavement. It has high strength and low cost. It is widely used in high end highway construction. Today I would like to talk about why the use of geogrid can improve the road Strength and reduce road reflection cracking

1. The geogrid used on the roadbed and the pavement is not the same. The use of glass fiber geogrid on the pavement can effectively prevent the occurrence of rut reflection cracks and prevent the damage of cold shrinkage cracks to the road surface. Medium is a product that must be used. For example, when urban roads and cement roads are transformed into asphalt pavements, it is also necessary to use sheds for pavement enhancement. The roadbed is reinforced with steel-plastic lattice shed and plastic grille, which can prevent the settlement of soft soil roadbed

2. Whether the roadbed construction uses a steel-plastic geogrid with a larger mesh or a plastic geogrid with a smaller mesh, it should be selected according to the construction material of the subgrade. This is related to the bite force between the grating and the subgrade material. The greater the bite force, the greater the Strong durability.

The geogrid can reduce the reflection and cracking of the road surface. It is because the surface layer of the fiberglass geogrid is a layer of asphalt coating. During construction, it can be very well bonded with the asphalt mixture to form a whole. The tensile strength of the products of the grille is transferred to the overall pavement layer, and the reflection cracks are due to the existence of joints on the old concrete surface and the vertical shear displacement caused by the traffic load, and the geogrid can well prevent The occurrence of this phenomenon.

The above is the use of geogrid sheds to improve the strength of roadbeds and reduce pavement reflection cracks. When you encounter any confusion when choosing geogrid, you can communicate with us at any time.
