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 Specification:

Glass Fiber Geogrid Features:

  It can be widely used in engineering fields such as old cement pavement, airport runway maintenance, embankment, river bank, slope protection and road bridge pavement reinforcement treatment. It can strengthen and reinforce the pavement and prevent pavement rutting fatigue cracks, It can disperse the bearing stress of the pavement, prolong the service life of the pavement, have high tensile strength, low elongation, no long-term creep, good physical and chemical stability, good thermal stability, anti fatigue cracking, high-temperature rutting, anti low-temperature shrinkage cracking, delay and reduce reflection cracks.

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.
