Fiberglass Geogrid

Fiberglass geogrid is an excellent geosynthetic material used for road surface reinforcement, old road reinforcement, roadbed reinforcement and soft soil foundation. Glass fiber geogrid is a semi-rigid product made of high-strength alkali-free glass fiber through the international advanced warp knitting process as a mesh base material and surface coating treatment. It has high tensile strength and low elongation in the two directions of warp and weft, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance, and corrosion resistance. It is widely used in asphalt pavement, cement pavement and roadbed reinforcement and railway Roadbed, dam slope protection, airport runway, sand prevention and sand control and other engineering projects.

    Fiberglass geogrid is an excellent geosynthetic material used for road surface reinforcement, old road reinforcement, roadbed reinforcement and soft soil foundation. Glass fiber geogrid is a semi-rigid product made of high-strength alkali-free glass fiber through the international advanced warp knitting process as a mesh base material and surface coating treatment. It has high tensile strength and low elongation in the two directions of warp and weft, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance, and corrosion resistance. It is widely used in asphalt pavement, cement pavement and roadbed reinforcement and railway Roadbed, dam slope protection, airport runway, sand prevention and sand control and other engineering projects.

    main ingredient
    The main components of glass fiber are: silica, which is an inorganic material. Its physical and chemical properties are extremely stable, and it has high strength, high modulus, high wear resistance and excellent cold resistance, no long-term creep; thermal stability Good performance; the network structure makes the aggregate interlock and limit; improves the load-bearing capacity of the asphalt mixture. Because the surface is coated with special modified asphalt, it has double composite properties, which greatly improves the wear resistance and shearing capacity of the geogrid.

    features
    1) High tensile strength, low elongation - glass fiber geogrid is made of glass fiber, which has a high resistance to deformation, and the elongation at break is less than 3%.
    2) No long-term creep—as a reinforcing material, it is extremely important to have the ability to resist deformation under long-term loads, that is, creep resistance. Glass fibers will not creep, which ensures that the product can maintain its performance for a long time.
    3) Thermal stability - the melting temperature of glass fiber is above 1000°C, which ensures the thermal stability of glass fiber geogrid during paving operations.
    4) Compatibility with asphalt mixture - the material coated in the post-treatment process of glass fiber geogrid is designed for asphalt mixture, and each fiber is fully coated, which is highly compatible with asphalt This ensures that the fiberglass geogrid will not be isolated from the asphalt mixture in the asphalt layer, but firmly combined.
    5) Physical and chemical stability - After being coated with a special post-treatment agent, the fiberglass geogrid can resist various physical wear and chemical erosion, and can also resist biological erosion and climate change, ensuring that its performance will not be affected.
    6) Aggregate interlocking and restriction - Since the fiberglass geogrid is a network structure, aggregates in asphalt concrete can run through it, thus forming a mechanical interlocking. This restriction hinders the movement of the aggregate, allowing the asphalt mixture to achieve better compaction under load, higher load-bearing capacity, better load transfer performance and less deformation.

    The main purpose
    1. For the old asphalt concrete pavement, reinforce the asphalt surface layer to prevent and control diseases.
    2. The cement concrete pavement is rebuilt into a composite pavement to suppress reflection cracks caused by plate shrinkage.
    3. For road expansion and improvement projects, prevent cracks at the junction of old and new joints and uneven settlement.
    4. Reinforcement treatment of soft soil foundation is conducive to the consolidation of soft soil by water precipitation, effectively inhibiting settlement, uniform stress distribution, and enhancing the overall strength of the roadbed.
    5. The semi-rigid base of the newly built road produces shrinkage cracks, and the reinforcement is reinforced to prevent the road surface cracks caused by the reflection of the foundation cracks.

    construction technology
    (1) First, release the side slope line of the subgrade accurately. In order to ensure the width of the subgrade, each side is widened by 0.5m. After leveling the air-dried base soil, statically press it twice with a 25T vibratory roller, and then four times with a 50T vibratory roller. , The uneven place is artificially leveled.
    (2) Pave the medium (coarse) sand with a thickness of 0.3m. After manual leveling with mechanical leveling, the 25T vibratory roller will statically press it twice.
    (3) Lay geogrids. When laying geogrids, the bottom surface should be flat and dense. Generally, they should be laid flat, straightened, not overlapped, curled or kinked. Two adjacent geogrids need to overlap 0.2m, and The overlapping part of the geogrid along the lateral direction of the subgrade is connected with No. 8 iron wire every 1 meter, and on the laid grid, it is fixed on the ground with U-shaped nails every 1.5-2m.
    (4) After the first layer of geogrid is laid, start to fill the second layer of 0.2m thick medium (coarse) sand. The method: transport the sand to the construction site by car and unload it on the side of the roadbed, and then push it forward with a bulldozer First, fill 0.1m within 2m on both sides of the subgrade, then turn over the first layer of geogrid and fill it with 0.1m of medium (coarse) sand. This kind of machine works on the geogrid that has not been filled with medium (coarse) sand, so as to ensure that the geogrid is flat and does not bulge or wrinkle. After the second layer of medium (coarse) sand is flat, it must be leveled. Measure to prevent uneven filling thickness. After the leveling is correct, use a 25T vibratory roller to statically press it twice.
    (5) The construction method of the second layer of geogrid is the same as that of the first layer. Finally, 0.3m of medium (coarse) sand is filled. The filling method is the same as that of the first layer. After static pressure twice with a 25T road roller, this The reinforcement of the subgrade base is completed.
    (6) After rolling the medium (coarse) sand in the third layer, lay two geogrids on both sides of the slope along the longitudinal direction of the line, with an overlap of 0.16m, and connect them in the same way, and then start the earthwork construction work, When laying geogrid for slope protection, it is necessary to measure the paved sideline for each layer, and ensure that the geogrid is buried 0.10m inside the slope after slope repair.
    (7) Every time two layers of soil are filled with slope geogrids, that is, when the thickness is 0.8m, a layer of geogrids needs to be laid on both sides at the same time, and so on, until it is laid under the surface soil of the road shoulder.
    (8) After the subgrade is filled, the side slope shall be repaired in time, and the dry rubble protection shall be carried out at the foot of the slope. In addition to widening the subgrade by 0.3m on each side, 1.5% of the settlement shall be reserved.
