Product characteristics

1. The products have the advantages of high strength, low elongation, high-temperature resistance, high modulus, lightweight, good toughness, corrosion resistance, long life, and so on. They can be widely used in old cement pavement, airport runway maintenance, dike, riparian, slope protection, road and bridge pavement reinforcement, and other engineering fields, which can strengthen and reinforce the pavement, and prevent rut fatigue cracks, hot and cold expansion cracks and reflection cracks below. It can disperse the bearing stress of the pavement and prolong the service life of the pavement.

2. High tensile strength and low elongation: glass fiber geogrid is made of glass fiber, and the tensile strength of glass fiber is very high, which is higher than that of other fibers and ordinary metals. At the same time, its modulus is very high, it has high deformation resistance, and the fracture elongation is less than 3%.

3. No long-term creep: as a reinforcing material, it is very important to have the ability to resist deformation under long-term load, that is, the creep resistance of glass fiber will not occur, which ensures that the product can maintain its performance for a long time.

4. Good physical and chemical stability: after coating with a special post-treatment agent, glass fiber geogrid can resist all kinds of physical wear and chemical erosion, and can also resist biological erosion and climate change, to ensure that its performance is not lost.

5. Good thermal stability: the melting point of glass fiber is above 1000 ℃, which ensures the stability of glass fiber geogrid under high temperatures in paving operations.

6. Lock and limit the aggregate: because the glass fiber geogrid is a reticulated structure, the aggregate in asphalt concrete can run through it, which forms a mechanical lock. This restriction hinders the movement of aggregate so that asphalt mixture can achieve a better compaction state, higher load-bearing capacity, better load transfer performance, and smaller deformation under load.

7. Compatibility with asphalt mixture: the material coated with glass fiber geogrid in the post-treatment process is designed for asphalt mixture, each fiber is fully coated and has high compatibility with asphalt, thus ensuring that glass fiber geogrid will not be isolated from asphalt mixture in asphalt layer, but will be firmly combined.

8. Fatigue cracking resistance: the glass fiber geogrid can disperse the compressive stress and tensile stress produced by pressing the wheel over the pavement, and forming a buffer zone between the two stress regions, the stress changes step by step rather than the sudden change, which reduces the damage of the asphalt surface caused by the sudden change of stress. At the same time, the low elongation of glass fiber geogrid reduces the deflection of the pavement and ensures that the pavement will not be over-deformed.

9. High-temperature resistant rut: glass fiber geogrid is used in the asphalt surface layer, which plays a skeleton role in the asphalt surface layer. The aggregate in asphalt concrete runs through the grille, forms the compound mechanics inlay lock system, restricts the aggregate movement, increases the transverse binding force in the asphalt surface layer, and each part of the asphalt surface layer restrains each other, thus preventing the passage of the asphalt surface layer and thus playing the role of resisting rut.

10. Resistance to low-temperature shrinkage: at low temperatures, asphalt concrete does not shrink as expected, resulting in tensile stress, when the tensile stress exceeds the tensile strength of asphalt concrete, cracks occur. The application of glass fiber geogrid in asphalt surfaces improves the transverse tensile strength of asphalt concrete and greatly improves the tensile strength of asphalt concrete, which can resist large tensile stress without damage. In addition, even if the crack occurs in the local region, the stress concentration of the crack will disappear through the transmission of the glass fiber geogrid, and the crack will not develop into a crack.

11. Delay and reduce reflection crack: add glass fiber geogrid flat layer in asphalt, restrain shear or tensile stress caused by traffic load, and release strain, as tensile reinforcement material of asphalt concrete, achieving the purpose of delaying and reducing crack.

3. The road reconstruction project can prevent the cracks caused by the new and old joints and uneven settlement.

4. The reinforcement treatment of soft soil foundation is beneficial to the consolidation of soft soil water evolution, the effective suppression of settlement, the uniform stress distribution and the enhancement of the overall strength of subgrade.

5. The semi-rigid base of the new road produces shrinkage crack, which is strengthened to prevent the pavement crack caused by the reflection of foundation crack.
