Fiberglass grating is an enhancement for the road, the old reinforcement, good geotextile reinforcement of soft soil subgrade and base of synthetic materials. On reflection asphalt pavement crack application processing has become an irreplaceable material. The product is made of high-strength alkali stripped fiber mesh substrate for fine through international advanced technology, the surface treatment and made a chart of office rigid products. Features: 1, high tensile strength: glass fiber strength / weight ratio than steel large, the elastic modulus of concrete and asphalt elastic modulus ratio of 20:1 up to prevent reflective cracking provides sufficient strength; 2, low Elongation: fiberglass geogrid material is a glass fiber having a high modulus of elasticity and resistance to deformation, elongation at break of less than 4%; 3, the thermal stability: the melting point of the glass fibers above 1000 ℃, This ensures that the fiberglass geogrid exposed to excessive heat in the paving job stability; 4, with the asphalt mixture Compatibility: fiberglass geogrid in the treatment process for the coating material is asphalt design, each fiber is sufficiently coated with bitumen has high compatibility, thus ensuring fiberglass geogrid is not isolated from the mixture to produce the asphalt, but firmly together in the asphalt layer; 5, no long-term creep: as a reinforcing material, the ability to load in the case of long-term resistance to deformation that creep resistance is extremely important, glass fibers do not creep occurs, and ensure that products can maintain long-term performance; 6. physical and chemical stability; through a special post-coating treatment after treatment agent, fiberglass geogrid can resist all kinds of physical abrasion and chemical attack, but also against biological erosion and climate change, to ensure that its performance is not lost; 7, set material embedded lock and limitations: Because fiberglass mesh geogrid is a combination of asphalt concrete aggregate can be running through them, thus forming a mechanical interlocking, such restrictions hinder the movement of aggregates, asphalt mix in the affected the case of a load state of compaction to achieve better and better load bearing capacity and better performance and less load transmission distortion. Applications range; an old asphalt concrete pavement, reinforced asphalt surface enhancement, disease prevention and control. 2, the cement concrete pavement composite pavement reconstruction, inhibit the contraction caused by the reflection plate cracks. 3, road extension project, combining old and new prevention department and uneven subsidence caused cracks. 4, soft soil reinforcement radical treatment, the water is conducive to the consolidation of soft soil analysis, effectively inhibit the settlement, uniform stress distribution, and enhance the overall strength of the roadbed. 5, new roads semi-rigid base shrinkage cracks, reinforced reinforced foundation cracks to prevent reflections caused pavement cracks.

Construction methods currently used fiberglass geogrid with self-adhesive and self-adhesive without the two, with a self-adhesive can be laid at the grassroots level have a direct, non-self-adhesive, usually using a nail fixation . Not self-adhesive fiberglass grid construction materials needed for nail fixation method is:. I fixed metal 40 × 40 × 0.3 mm, requiring no Qiaojiao ii 2 英寸 flat nails (quality concrete nails) 1, nails fixed. law laying fiberglass geogrid, the first end of the fixed iron and nails fixed substructure has been spilled on the cloth sticky layer of asphalt, hammering nails or nail gun incident available, then grill longitudinal tension and points Fixed segments, each length of 2-5 meters, for cement concrete pavement, according to the contraction joint spacing segments. Pinning position located at the seams, requiring grill taut, its vertical and horizontal are in a straight tension. 2, grille lap distance: a longitudinal lap joints distance of not less than 20 cm horizontal lap distance not less than 15 cm, longitudinal lap asphalt paving should be based on the direction of the front piece after piece is above. 3, you can not nail on fiberglass grating, nor can hammer direct percussion fiberglass grating, fixed after breaking a nail or metal found loose, you need to re-fixed. 4, fiberglass grating fixed laying has been completed, subject to moderate stability with plastic roller compaction roller. Sticky surface of the grille and backtrack firm, strict control mix delivery vehicle access to vehicular sharp turn on the grid layer, and pour the mixture foot braking material to prevent damage to the fiberglass grating construction. Construction method of a self-adhesive fiberglass grating, ready to work: Complete all the caulk, fill the pit, laying the foundation reinforcement and leveling layers. 2, road surface condition of the road surface must be: clean dust-free, dry, temperatures between 5 degrees -60 degrees Celsius. 3, the product is ready to self-adhesive fiberglass geogrid at the site may not be stored in a dry environment to remain sticky. 4 Notes (1) self-adhesive fiberglass grating contact, workers must wear gloves. (2) When the self-adhesive fiberglass grid paved road signs obstacles hinder this position must be cut with a knife geogrid. (3) Self-adhesive fiberglass grating when laying out the pleats are not allowed, so the laying process, there must be sufficient tension. Overlap portion (4) side lap 75-150 mm, laid down to ensure that the direction of the overlap portion. (5) overlapping both sides of the overlap portion 25-50 mm. (6) After laying and compaction, allowing only emergency vehicles or construction vehicles traveling on it, but should ensure that no cornering or braking of the vehicle due to the geogrid damage. (7) have been laid geogrid road must be completed at the date of the laying of asphalt work, the minimum thickness of the surface layer of asphalt should be greater than 40 mm. 5, paving method (1) Machinery laying the entire volume geogrid unwinding rack mounted on the front of the tractor, pay attention to its sticky face. So the tractor to move forward, to ensure geogrid straight glued to the pavement. s rolling 1-2 times with a lightweight rubber tire roller. Paving asphalt pavement. (2) paved the entire volume geogrid on the truck or trolley unwinding rack, pay attention to its sticky face. Make sure to put the reel is locked, without freedom of loose rolls. When the truck (or trolley) slowly moving forward, should slam the end of the grill. If the grid when there is slack, real-time adjustments to prevent wrinkles. With a light roller tire rolling 1-2 times, you can activate the grille gum paving asphalt pavement.
