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:

Glass fiber geogrid
1) High tensile strength and low elongation - glass fiber geogrid is made of glass fiber, which has high deformation resistance, and the fracture elongation is less than 3%.
2) No long-term creep - as a reinforcing material, it has the ability to resist deformation under long-term load, that is, creep resistance is very important. Glass fiber will not creep, which ensures that the product can maintain its performance for a long time.
3) Thermal stability - the melting temperature of glass fiber is above 1000 ℃, which ensures the thermal stability of glass fiber geogrid during paving operation.
4) Compatibility with asphalt mixture - the materials coated by glass fiber geogrid in the post-treatment process are designed for asphalt mixture. Each fiber is fully coated and has high compatibility with asphalt, so as to ensure that glass fiber geogrid will not be isolated from asphalt mixture in the asphalt layer, but firmly bonded together.
5) Physicochemical stability - after coating with special post-treatment agent, glass fiber geogrid can resist all kinds of physical wear and chemical erosion, biological erosion and climate change, so as to ensure its performance is not affected.
6) Aggregate interlocking and limitation - because the glass fiber geogrid is a network structure, the aggregate in asphalt concrete can penetrate it, which forms a mechanical interlocking. This restriction hinders the movement of aggregate, so that asphalt mixture can achieve better compaction state, higher bearing capacity, better load transfer performance and less deformation under load.

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.
