Uniaxial Geogrid Features
- Tensile Strength: Uniaxial geogrids(https://geolianyi.com/product/pp-uniaxial-geogrid/)have high tensile strength in one primary direction, known as the machine direction (MD). This strength enables them to withstand significant loads and distribute forces effectively.
- Aperture Size: Uniaxial geogrids(https://geolianyi.com/product/hdpe-uniaxial-geogrid/)feature a regular grid structure with uniform apertures or openings. The aperture size can vary depending on the specific application and desired engineering properties.
- Rib Structure: These geogrids consist of ribs that run in the machine direction and are interconnected by junctions. The ribs provide stiffness and structural integrity, while the junctions facilitate load transfer between adjacent ribs.
- Strain Characteristics: Uniaxial geogrids exhibit low strain characteristics, meaning they have a minimal tendency to deform or elongate under load. This property helps maintain their integrity and load-bearing capacity over time.
- Durability: Geogrids are designed to have excellent resistance to environmental factors such as chemical attack, UV degradation, and biological degradation. This durability ensures long-term performance in various soil conditions.
- Soil Interaction: Uniaxial geogrids form a mechanical bond with the surrounding soil, creating an interlocking effect. This interaction enhances soil reinforcement and provides stability to slopes, retaining walls, and other structures.
7.Installation Efficiency: Uniaxial geogrids are typically supplied in roll form, allowing for easy transportation, handling, and installation. They can be deployed horizontally or vertically, depending on the specific application, and are commonly used in reinforcement layers within soil structures.

Asphalt Fiberglass GeogridFeatures
High strength and low elongation: It has a very high tensile strength in both the warp and weft directions, a low elongation, and can effectively withstand external forces, reducing deformation.
Stable performance: It features excellent properties such as high-temperature resistance, low-temperature resistance, anti-aging, and corrosion resistance, and can adapt to various complex environments.
Easy construction: Light in weight, with certain flexibility, it is easy to cut and connect on site, can be overlapped and lapped, and does not require special construction machinery or professional technicians.
Fiberglass Geogrids(https://geolianyi.com/product/fiberglass-geogrids/)Advantages
Slow down reflective cracks: It can suppress stress and release strain. As a hard interlayer with high rigidity, it enhances the tensile and shear resistance of the overlay structure and reduces cracks.
Anti-fatigue cracking: A buffer zone is formed between the stressed areas, allowing the stress to gradually change, reducing the damage caused by sudden stress changes to the asphalt overlay layer. At the same time, the low elongation rate reduces the deflection of the pavement.
High-temperature rutting resistance: It plays a skeletal role in the asphalt surface layer, forming a composite mechanical interlocking system, restricting the movement of aggregates, preventing the asphalt surface layer from pushing, and resisting rutting.
Resistance to low-temperature shrinkage cracking: Enhance the tensile strength of asphalt concrete, resist tensile stress, and even if local cracks occur, the stress can be gradually eliminated through it, preventing the cracks from developing into cracks.

How To Use Warp Knitted Polyester Geogrid?
Polyester geogrid should be laid on coarse grained stone of asphalt layer of construction pavement, the original pavement should be leveled first, constructed after finishing, repairing and cleaning, fixed PET geogrid overlap with special steel nails is needed for ordinary woven polyester geogrid, joint transverse greater than 5 cm, longitudinal greater than 10 cm, PVC coated polyester geogrid treated with asphalt should be laid as little as possible with asphalt adhesive oil, and self-adhesive. The asphalt mixture can be paved and compacted after proper rolling by rubber wheel roller in the construction of knitted polyester geogrid without special steel nails.
