Product Name: Fiberglass Geogrid Model NO.: 30kn-80kn Material: Plastic Classification: Plastic Geogrid Function: Anti-slip, Reinforcement Viscose: With Viscose Application: Retaining Wall, Steep Slop, Dam, Road base Color: Black Transport Package: Woven Bag Specification: 6*50 Origin: Laiwu District, Jinan City, Shandong Province, Chi HS Code: 5603939000 Product Description Glass fiber grid (EGA) is the abbreviation of glass fiber geogrid. High quality reinforced non alkali glass fiber yarn is selected, which is woven into base material by foreign advanced warp knitting machine. The warp knitting directional structure is adopted to make full use of the yarn strength in the fabric, improve its mechanical properties, and make it have good tensile strength, tear strength and creep resistance. The plane network material is coated with high quality modified asphalt. According to the principle of similar compatibility, the composite performance of the asphalt mixture is highlighted, and the glass fiber base material is fully protected, which greatly improves the wear resistance and shear resistance of the base material, so that it can be used for road reinforcement, resist the occurrence of road diseases such as cracks and ruts, and end the difficult problem of strengthening the asphalt pavement.Glass fiber geogrid is a kind of excellent geosynthetic material used for Pavement Reinforcement, old road reinforcement, subgrade reinforcement and soft soil foundation. It has become an irreplaceable material in dealing with reflective cracks of asphalt pavement. The product is a semi-rigid product which is made of high-strength alkali free glass fiber through international advanced warp knitting technology and coated on the surface. It has high tensile strength, low elongation and high temperature resistance, low cold resistance, anti-aging and corrosion resistance. It is widely used in asphalt pavement, cement pavement and roadbed reinforcement, railway subgrade, embankment revetment, airport runway, sand prevention and other engineering projects.Product characteristics The products have the characteristics of high strength, low elongation, high temperature resistance, high modulus, light weight, good toughness, corrosion resistance, long service life, etc., which can be widely used in the old cement pavement, airport runway maintenance, embankment, river bank, slope protection, road and Bridge Pavement Reinforcement and other engineering fields, can strengthen and strengthen the pavement, prevent the pavement rut fatigue crack, hot and cold expansion crack and the following Reflection crack can disperse the bearing stress of the road surface, prolong the service life of the road surface, have high tensile strength and low elongation, no long-term creep, good physical and chemical stability, good thermal stability, anti fatigue crack, high temperature rutting resistance, low temperature shrinkage crack resistance, delay and reduce reflection crack.Product use 1. The old asphalt concrete pavement shall be reinforced to strengthen the asphalt surface and prevent diseases. 2. Cement concrete pavement shall be reconstructed into composite pavement to prevent reflection cracks caused by plate shrinkage. 3. Road expansion and reconstruction project to prevent cracks caused by new and old junction and uneven settlement. 4. The reinforcement treatment of soft soil foundation is conducive to the consolidation of soft soil by water separation, effective settlement control, uniform stress distribution and overall strength of subgrade. 5. The semi-rigid base of the new road will produce shrinkage cracks, and the reinforcement will be strengthened to prevent the pavement cracks caused by the reflection of the foundation cracksConstruction methodThere are two kinds of common fiberglass geogrid: with self-adhesive and without self-adhesive. Those with self-adhesive can be directly laid on the leveled base. Those without self-adhesive are usually fixed with nails. Construction method of non self adhesive glass fiber grid The materials required for nail fixation are:40 × 40 × 0.3 mm fixed iron sheet, which is required to be flat without warping angleinch steel nails (high quality cement nails) 1. When laying fiberglass geogrid with nail fixing method, one end shall be fixed on the substructure sprayed with tack coat asphalt with fixed iron sheet and nail. The nail can be shot in with hammer or nail gun, and then the grid shall be tensioned longitudinally and fixed in sections with length of 2-5M. For cement concrete pavement, it can be divided into sections according to the spacing of contraction joints. The position of the steel nail is set at the joint. When the grid is required to be tensioned, its vertical and horizontal directions are in a straight and tensioned state. 2. The overlapping distance of Grid: the overlapping distance of longitudinal joint shall not be less than 20cm, and that of transverse joint shall not be less than 15cm. The former one shall be placed above the latter one according to the asphalt paving direction. 3. It is not allowed to nail the nail on the glass fiber grid, or directly knock the glass fiber grid with a hammer. If the nail is broken or the iron sheet is loose after fixing, it needs to be fixed again. 4. After the glass fiber grid is laid and fixed, it shall be rolled and stabilized by rubber roller. Make the grid and the original road surface stick firmly, strictly control the access of vehicles transporting the mixture, and forbid the vehicles to swerve, brake and pour the mixture feet on the grid layer, so as to prevent the construction damage to the fiberglass grid. Construction method of self adhesive glass fiber grating 1. Preparation: Complete all joint filling, pit filling, foundation reinforcement and leveling layer laying. 2. Road surface conditionThe road surface must be clean, dry and at a temperature between 5 ° C and 60 ° C. 3. Product preparation The self-adhesive fiberglass geogrid shall not be kept in dry environment at the construction site to maintain its viscosity. 4. Precautions (1) Workers must wear gloves when contacting the self-adhesive fiberglass grille. (2) When the self-adhesive glass fiber grid is used to pave the road sign obstacles, the geogrid that hinders this position must be cut off with a knife. (3) Pleats are not allowed when laying the self-adhesive glass fiber grid, so there must be enough tension during the laying process. (4) Lap the end laps 75-150 mm, making sure the laps follow the direction of laying. (5) Overlap 25-50mm on both sides. (6) After laying and rolling, only construction vehicles or emergency vehicles are allowed to walk on it, but the geogrid shall not be damaged due to vehicle turning or braking. (7) For the paved geogrid pavement, the asphalt mixture must be laid on the same day, and the minimum thickness of the surface asphalt shall be more than 40mm. 5. Laying method (1) Mechanical laying Install the whole roll of Geogrid on the unwinder in front of the tractor, and pay attention to its viscosity facing down. Move the tractor forward to make sure that the geogrid is flat on the road.Use the light roller of rubber wheel to roll for 1-2 times.Pave asphalt mixture pavement. (2) Manual laying Place the whole roll of Geogrid on the back of the truck or on the unwinding frame of the trolley, and pay attention to its sticky side downward. Make sure that the unwinder is locked and the cloth is not loose. When the truck (or trolley) moves slowly forward, step on one end of the grille. If the grid is loose, adjust it immediately to prevent wrinkles. Use the light roller of rubber wheel to roll for 1-2 times, activate the back glue of grid to pave the asphalt pavement.
