Description: glass fiber geogrid is a new type of geogrid with excellent properties, such as high tensile strength, good elastic modulus, low elongation, high and low temperature resistance and aging resistance, especially after surface modification and coating treatment of glass fiber grid.
 Glass fiber geogrid

? Glass fiber geogrid It has high tensile strength, good elastic modulus, low elongation, high and low temperature resistance and aging resistance Especially after the surface modification and coating treatment of glass fiber grid, the composite performance with asphalt or concrete is improved, and the wear resistance and shear resistance of the substrate are enhanced. In highway construction, it is difficult to replace other high-grade soil foundation materials, especially in other fields. ?

? ? Glass fiber grid has the following characteristics :?
A: high tensile strength: the strength / weight ratio of glass fiber is larger than that of steel, and its elastic modulus and asphalt elastic ratio can reach 20:1 at 20 ℃, which provides sufficient rigidity for delaying the development of reflection cracks. ?
The long-term creep resistance of the glass fiber is not guaranteed as long-term creep resistance. ?
C: compatibility with asphalt mixture: the coating material of glass fiber grid in post-treatment process is designed for asphalt mixture, each fiber is fully coated, and has high compatibility with asphalt, which ensures that glass fiber grid is not isolated from asphalt mixture in asphalt, but firmly combined. ?
D: interlocking and limiting effect of aggregate - because the glass fiber grid is a grid structure, the aggregate in concrete can run through it, which limits and hinders the movement of aggregate. Asphalt mixture can get better compaction, greater bearing capacity, and can improve load transfer performance and reduce deformation.
