Fiberglass Geogrid Specially used in Pavement
Resistance to Fatigue Cracking
The fiberglass geogrid in asphalt surface can disperse the compressive strength and tensile strength produced when wheels rolled over the pavement. Buffer zone will be formed between two strength areas, and the strength is gradually changed rather than suddenly changed, thus the damage of strength to the asphalt surface is reduced. In the mean time, low elongation rate of the fiberglass geogrid reduced the deflection of the pavement, and protect the pavement from excessive deformations.
High Temperature Rutting Resistant
When using fiberglass geogrid in asphalt surface, it acts as skeleton in the surface. Aggregate in the asphalt concrete exists throughout the grid. A composite constraint force in the asphalt surface. The mutual containment of each other in asphalt surface prevents the bed-load of the asphalt surface and resists the effects of rutting.
Low temperature shrinkage cracking resistant
In low temperature, asphalt concrete will shrink in cold and tensile strength will be produced. If the tensile strength exceeds the tensile strength of asphalt concrete, it will crack. The application of fiberglass geogrid in asphalt surface, improves the horizontal tensile strength of the surface, and greatly improves the tensile strength of asphalt concrete, thus great tensile strength can be resisted without any damage. In addition, even if some area cracks, the strength in the crack will disappear in their transmission in fiberglass geogrid. Cracks will not develop into fissures.
Delay and reduce reflective fissures
Through paving fiberglass geogrid interlayer in the asphalt, the shearing or tensile strength caused by traffic load will be resisted, strain will be released. It will act as tensile improvement material of asphalt concrete, and the purpose to delay and reduce fissures will be achieved.
