Lianyi®Asphalt Grid is a kind of mesh structure material made of glass fiber through certain weaving techniques. To protect the glass fiber yarns and improve the overall performance, it undergoes a special coating treatment process to form a geocomposite material.
Asphalt Grid is a new type of excellent geosynthetic base material for reinforcing road surfaces and roadbeds. This product is made by weaving and coating glass fiber filaments yarns.Asphalt Grid feature extremely high tensile strength in both longitudinal and transverse directions, low elongation, high elastic modulus, and excellent resistance to high and low temperatures. After surface coating treatment, they possess superior alkali resistance and aging resistance, and are widely used in the reinforcement of asphalt pavements, cement concrete pavements, and roadbeds. It is applicable to both hard and flexible road surfaces.Compared with traditional road surfaces, it can reduce costs, extend service life and prevent reflective cracks on the road. Asphalt Grid can also be used for reinforcing soft soil in railways, airports, water conservancy projects, DAMS, etc., as well as for reinforcing road bases.
*High tensile strength and low elongation – Asphalt Grid are made of glass fiber yarns and have a very high resistance to deformation, with a fracture elongation of less than 3%.
*No long-term creep – As a reinforcing material, the ability to resist deformation under long-term loads, that is, creep resistance, is extremely important. Asphalt Grid do not creep, which ensures that the product can maintain its performance for a long time.
*Thermal stability – The melting point of glass fiber yarns is above 1000℃, which ensures the thermal stability of the Asphalt Grid during the paving operation.
*Compatibility with asphalt mixture – The material coated on the Asphalt Grid in the post-treatment process is designed for asphalt mixture. Each fiber is fully coated, which has a high compatibility with asphalt. This ensures that the Asphalt Grid will not be isolated from the asphalt mixture in the asphalt layer but will be firmly combined together.
*Physical and chemical stability – After being coated with special post-treatment agents, Asphalt Grid can resist various physical wear and chemical erosion, as well as biological erosion and climate change, ensuring that their performance remains unaffected.
*Aggregate interlocking and confinement – As the Asphalt Grid is a mesh structure, the aggregates in the asphalt concrete can pass through it, thus forming mechanical interlocking.This restriction hinders the movement of aggregates, enabling the asphalt mixture to achieve a better compaction state, higher load-bearing capacity, better load transfer performance and less deformation under load.
