Glass Fiber Geogrid Introduction
There are several kinds of geogrids, of which glass fiber grille is commonly used. There are layers of asphalt on the surface of glass fiber grille, which is high temperature resistant, anti-aging and corrosion resistant. Asphalt concrete pavement is widely used in highway construction in China. However, the load stress will cause serious damage to the asphalt concrete pavement and shorten the service life of the highway.
Therefore, in order to improve the quality of asphalt concrete pavement, measures should be taken to improve its stability. For example, by increasing the application of geogrid, the quality of asphalt concrete pavement can be effectively improved.

Glass Fiber Geogrid Features:
Sometimes, it is combined with self-adhesive pressure sensitive adhesive and surface asphalt impregnation treatment to closely integrate the grid and asphalt pavement. As the interlocking force of earth and stone in the geogrid grid grid increases, the friction coefficient between them increases significantly (up to 08 ~ 10). The uplift resistance of geogrid embedded in soil increases significantly due to the strong friction bite force between grid and soil, so it is a good reinforcement material. At the same time, geogrid is a kind of plastic plane mesh material with light weight and certain flexibility. It is easy to cut and connect on site, and can also be overlapped and overlapped. The construction is simple and does not need special construction machinery and professional technicians.
Glass Fiber Geogrid Application:
Slow reflection crack
The reflection crack is caused by the stress concentration in the asphalt overlay above the old concrete surface caused by the large displacement near the joint or crack. It includes the horizontal displacement caused by the change of temperature and humidity and the vertical shear displacement caused by traffic load. The former causes more concentrated tensile stress in the asphalt overlay above the joint or crack; The latter makes the asphalt overlay above the joint subject to large bending tensile stress and shear stress.
Because the modulus of geogrid is very large, reaching 67gpa, it is applied in the asphalt overlay as a hard interlayer with high stiffness. Its function is to relieve stress and release strain. At the same time, it is used as the reinforcement material of asphalt concrete to improve the tensile and shear capacity of the overlay structure, so as to reduce cracks. The practice shows that the corresponding crack energy of a horizontal crack with changed direction can move 0.6m from its starting point, and the reinforced material with a width of more than 1.5m helps to ensure the complete dissipation of energy on both sides of the crack.
Construction method Glass Fiber Geogrid
1. Preparation:
Complete all joint filling, pit filling, foundation reinforcement and leveling layer laying.
2. Road surface condition
The road surface must be clean and dry with a temperature between 5 ℃ and 60 ℃.
3. Product preparation
The self-adhesive glass fiber geogrid shall not be kept in a dry environment to maintain its viscosity at the construction site.
