Lianyi® Biaxial Geogrid is a new type of geosynthetic material used in civil engineering and road construction projects. They are typically made from polypropylene (PP),fiberglass yarns or polyester yarns and are characterized by their unique structural properties.
Tensile Strength: Biaxial geogrid has high tensile strength in two directions,known as the machine direction (MD) and cross direction(CD).This strength enables them to withstand significant loads and distribute forces effectively.
Aperture Size: Biaxial geogrid features 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: Biaxial geogrid 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: Biaxial geogrid is 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: Biaxial geogrid 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.
Installation Efficiency: Biaxial geogrid is 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.

Asphalt Fiberglass Geogrids Main Functions
Reinforcement of asphalt pavement
Fiberglass Geogrids are used to pave roads considerably reduce the reflective cracking on the course,decrease crack propagation speed,control the formation of ruts and lessen the internal stresses caused by temperature changes.Fiberglass Geogrids for asphalt reinforcement are ideal to improve the performances of roads superstructure,thus allowing them to meet the design requirements.Additionally,these fiberglass geogrids improve loads distribution on the wearing course and thus reduce the settlements.
Protection from Reflective Cracks
The use of asphalt fiberglass geogrids in asphaltic pavement system mitigates the risk of reflective crack formation.The fiberglass geocomposites reinforcement layer redistributes stresses horizontally in the overall system,thus preventing stress from concentrating and migrating upward to the surface as a crack.
Prevention of wheel track rutting
The high strength performance of the materials redistributes loads across the entire area of the reinforced road surface.This prevents the formation of wheel ruts,even in high temperature environments.

The Lianyi® Company is the manufacturer of the pp geogrids,specialized geosynthetics widely used in the civil engineering projects to stabilize and reinforce land or separate the substrate layers with varying graining.PP Geogrids are quick and easy to install and allow for the reduction of the use of materials,thus saving investment costs and time.
What’s PP Biaxial Geogrids?
Lianyi® PP Biaxial Geogrids are specifically designed for the stabilization and reinforcement of soil.These Geogrids are expertly manufactured by using different grades of Polypropylene(PP) and are produced using and extrusion and stretching method that yields Geogrids with highly increased tensile properties in both machine and transverse directions.
The manufacturing process produces a unique grid structure,consisting of high strength junctions and stiff ribs.When installed in the soil,the interlocking of the aggregate within the apertures of the Geogrids allows for the effective reinforcement of the soil.This interlock mechanism helps restrain lateral movement of aggregate particles.
How Do PP Biaxial Geogrids Work?
Immediate stabilization and reinforcement of road structure
The semi-stiff composite aggregate scheme allows for the reinforcement of aggregate,even on extremely low load-bearing surfaces.Blocking of the aggregate by the geogrid is a key factor during the pre-compaction of the road foundation,as well as for the further behaviour of the road in lifetime.A high elastic modulus(stiffness of geogrid)is considered to be the main feature which enables effective restriction of movement of the aggregate and as a result,an effective reinforcement of structure.
Blocking and horizontal fixing of aggregate
Thanks to the rigid construction based on non movable nods,which immediately responds to pressure,the PP Biaxial Geogrids prevent aggregate shifts.Used to reinforce the road structure,PP Biaxial Geogrids prevent horizontal displacement and penetration of aggregate grains into the weak substrate and the loss of stability of the foundation layer.
Separation
The PP Biaxial Geogrids placed between the road foundations and the subsoil work as a separator preventing the mixing of the materials with different grain size and load bearing capacity.Geogrids help avoid the penetration of aggregate into the weak substrate and the loss of stability of the foundation layer.
On boggy substructures or in case of materials of unfavourable grain size,where the separating function needs to be enhanced,PP Geocompsoites are used,PP Geogrids combined with non woven geotextile.
