Lianyi® Asphalt Grid is fiber glass yarns manufactured for asphalt reinforcement of paved surfaces.Asphalt grid is designed to prevent reflective cracking and reinforce asphalt pavements,providing strength and rigidity in a high strength glass fiber grid .
Asphalt grid is typically installed under the pavement’s wearing course and is designed to reinforce the surface course.It dissipates induced tensions which can lead to the risk of cracks,and can delay their appearance on the surface.
Asphalt grid is an engineered geogrid that is suitable for flexible road pavements,asphalt pavement and overall soil reinforcement.When properly installed,it offers a long design life,excellent performance and predictable in suit behaviour.
Classification Of Asphalt Grid
*Self Adhesive Fiberglass Geogrid
*Lowers maintenance costs
*Repairs severely cracked roads and postpones complete reconstruction
*Dramatically extends the life of roads, runways and parking lots
*Open aperture design promotes aggregate interlock between paving courses, greatly decreasing shear potential that is common with paving fabrics
*High stiffness, high modulus of elasticity, low elongation
*Effective bonding of grid during installation to leveling the prepared surface or course with patented adhesive backing(standard practice of use of tack coat is recommended to enhance or promote bonding between lifts of asphalt layers)
*Ease of constructability allows for asphalt grid installation and immediate placement of overlying pavement
*Asphalt reinforcement
*Reduce reflective cracking
*Prevent traffic induced shearing
*Extend road life
