The grid should be placed on the coarse-grained stone of the asphalt layer of the construction pavement. The original road surface should be leveled first, and then the construction should be carried out after trimming, trimming and cleaning. Ordinary grids need to be fixed with special steel nails. The seam is greater than 5 cm in the transverse direction and greater than 10 cm in the longitudinal direction. Asphalt-treated geogrids should be sprayed as little as possible with asphalt bonding layer oil. Self-adhesive gratings should be used during construction. After the asphalt mixture is properly rolled with a tire roller, it can be paved and compacted without special steel nails.
High-strength polyester geogrid is a new type of high-quality geotechnical foundation reinforcement material. It is made of high-strength polyester fiber or polypropylene fiber, which is made by warp knitting and special dip coating.
What are the characteristics of geogrids?
1. Has extremely high tensile strength.
2. Light weight, with drainage function.
3. Anti-corrosion and anti-aging.
4. Strong bite force with substrate.
