The characteristics of glass fiber geogrid

Jiangsu Hanovo New Material Co.,Ltd | Updated: May 25, 2018

Geogrid is divided into four categories: glass fiber geogrid, plastic geogrid, polyester geogrid and plastic geogrid.

The characteristics of glass fiber geogrid:

1: High tensile strength, low elongation - fiberglass geogrid is a glass fiber as raw material, has a high resistance to deformation, elongation at break is less than 3%.

2: No long-term creep - as a reinforcing material, with the ability to resist deformation in the case of long-term load, that is creep resistance is extremely important, glass fiber will not creep, this guarantees the product can maintain performance for a long time.

3: Thermal stability - glass fiber melting temperature above 1000 °C, which ensures that the fiberglass geogrid in the paving operation withstand thermal stability.

4: Compatibility with bitumen: The material coated with glass fiber geogrid in the post-treatment process is designed for asphalt mixtures. Each fiber is fully coated and has high compatibility with asphalt. Sexuality ensures that the fiberglass geogrid will not be isolated from the asphalt mixture in the asphalt layer, but firmly combined.

5: Physical and chemical stability: After being coated with a special post-treatment agent, the fiberglass geogrid can resist all kinds of physical wear and chemical attack, and it can also resist bio-erosion and climate change to ensure its performance is not affected.

6: Aggregate interlocking and restrictions - As the fiberglass geogrid is a mesh structure, aggregate in asphalt concrete can penetrate through it, so that the formation of a mechanical interlocking. This restriction hinders the movement of the aggregates and enables the asphalt mixture to achieve better compaction under load conditions, higher load-bearing capacity, better load transfer performance and less deformation.
