Glass Fiber Grid (abbreviated as EGA) is a shorthand for Glass Fiber Geogrid. It is made using reinforced alkali-free glass fiber yarn, woven into the base material with advanced foreign warp knitting machines. Employing warp-knitted directional structures, it maximizes the strength of the yarn within the fabric, enhancing its mechanical properties, resulting in excellent tensile strength, tear resistance, and蠕变 resistance. The material is then coated with modified asphalt for a flat, network-like structure. It follows the principle of "like dissolves like," emphasizing its composite properties with asphalt mixtures, while fully protecting the glass fiber base material. This enhances the base material's wear resistance and shear resistance, making it suitable for road reinforcement, preventing the formation of cracks and rutting, and solving the难题 of enhancing asphalt pavements.
Product Application:
1. Existing asphalt concrete pavement, reinforced asphalt surface treatment, and disease prevention.
2. Concrete road reconstruction to composite pavement, to suppress reflection cracks caused by plate shrinkage.
3. Road widening project to prevent and control cracks caused by the junction of new and old sections and uneven settlement.
4. Reinforcement treatment for soft soil foundation, conducive to water drainage and consolidation of soft soil, effectively controls settlement, ensures even stress distribution, and enhances the overall strength of the subgrade.
5. New road subgrade with semi-rigid base develops shrinkage cracks; reinforced reinforcement is used to prevent reflection of base cracks causing pavement cracks.
Important Notes:
When handling self-adhesive glass fiber grid, workers must wear gloves.
(2) When laying self-adhesive glass fiber geogrid over road sign obstructions, the geogrid at this location must be cut with a knife to remove any hindrance.
(3) When laying self-adhesive glass fiber grid, wrinkles are not permitted. Therefore, sufficient tension must be maintained during the laying process.
(4) The overlap section should be 75-150mm, ensuring the overlapping part runs along the laying direction.
(5) The overlap on both sides is 25-50 mm.
(6) After laying and compacting, only construction or emergency vehicles are permitted to travel on it, ensuring that the geogrid is not damaged due to vehicle turns or braking.
(7) Paved geotextile grids must have asphalt mixture laid the same day, with a surface asphalt thickness of over 40mm.
