Custom Asphalt Reinforcement Glass Fiber Geogrid

Custom Glass Fiber Grid Reinforced Soil Engineering Fiberglass Geogrid For Asphalt Reinforcement
 
 
Glass Fiber Geogrid Introduction
 
  Fiberglass Grid (EGA for short) is the abbreviation for Fiberglass Geogrid. Select high-quality reinforced alkali-free glass fiber yarn, use foreign advanced warp knitting machine to woven into the base material, adopt warp-knitting orientation structure, make full use of the yarn strength in the fabric, improve its mechanical properties, and make it have good tensile strength and resistance. A flat network material with tear strength and creep resistance and coated with high-quality modified asphalt. Based on the principle of similar compatibility, it focuses on its composite performance with asphalt mixtures, and fully protects the glass fiber substrate, which greatly improves the wear resistance and shear resistance of the substrate, so that it can be used for pavement reinforcement and resistance. The occurrence of road diseases such as cracks and ruts has ended the difficult problem of asphalt pavement reinforcement.
 
Glass Fiber Geogrid Specification:
 

 
Glass Fiber Geogrid Features:
 
  It can be widely used in engineering fields such as old cement pavement, airport runway maintenance, embankment, river bank, slope protection and road bridge pavement reinforcement treatment. It can strengthen and reinforce the pavement and prevent pavement rutting fatigue cracks, It can disperse the bearing stress of the pavement, prolong the service life of the pavement, have high tensile strength, low elongation, no long-term creep, good physical and chemical stability, good thermal stability, anti fatigue cracking, high-temperature rutting, anti low-temperature shrinkage cracking, delay and reduce reflection cracks.
 
Glass Fiber Geogrid Application:
 
Product use
1. The old asphalt concrete pavement shall be reinforced to strengthen the asphalt surface course and prevent diseases.
2. Cement concrete pavement is reconstructed into composite pavement to restrain reflection cracks caused by plate shrinkage.
3. Road expansion and reconstruction project to prevent cracks caused by new and old joint and uneven settlement.
4. The reinforcement treatment of soft soil foundation is conducive to the water precipitation and consolidation of soft soil, effectively inhibit settlement, uniform stress distribution and enhance the overall strength of subgrade.
5. The semi-rigid base course of the new road will produce shrinkage cracks, and the reinforcement will be strengthened to prevent the pavement cracks caused by the reflection of foundation cracks
 
Construction method  Glass Fiber Geogrid
(1) Firstly, the subgrade slope line shall be set out accurately. In order to ensure the subgrade width, each side shall be widened by 0.5m. After leveling the dried base soil, static pressure shall be carried out twice with 25t vibratory roller, and then 50t vibratory compaction shall be carried out four times. The uneven places shall be leveled manually.
(2) Pave 0.3m thick medium (coarse) sand. After manual and mechanical leveling, static pressure shall be applied twice with 25t vibratory roller.
(3) When laying the geogrid, the bottom surface of the geogrid shall be flat and dense. Generally, it shall be laid flat, straightened, without overlap, curl and kink. The two adjacent geogrids shall be overlapped for 0.2m, and the overlapped part of the geogrid shall be connected with No. 8 iron wire every 1m along the transverse direction of the subgrade, and the geogrid shall be fixed on the ground with U-nails every 1.5-2m.
(4) After the first layer of geogrid is paved, the second layer of 0.2m thick medium (coarse) sand shall be filled. The method: the sand shall be transported by truck to the construction site and unloaded on one side of the subgrade, and then pushed forward by bulldozer. After filling 0.1M within 2m on both sides of the subgrade, the first layer of geogrid shall be folded up and then filled with 0.1M thick medium (coarse) sand. Filling and pushing from both sides to the middle is prohibited, It is forbidden for all kinds of machinery to pass and operate on the geogrid without filling medium (coarse) sand, so as to ensure that the geogrid is flat, free from bulge and wrinkle. After the second layer of medium (coarse) sand is leveled, horizontal measurement shall be carried out to prevent uneven filling thickness. After leveling, static pressure shall be carried out twice with 25t vibratory roller.
(5) The construction method of the second layer of geogrid is the same as that of the first layer. Finally, 0.3m medium (coarse) sand is filled. The filling method is the same as that of the first layer. After static pressing twice with 25t roller, the subgrade base reinforcement is completed.
(6) After the third layer of medium (coarse) sand is rolled, two geogrids are laid on both sides of the slope longitudinally along the line, overlapping 0.16m, and connected in the same way, and then the earthwork construction operation is started. The geogrid is laid for slope protection. The laid sideline must be measured on each layer, and the geogrid shall be buried 0.10m in the slope after slope renovation on each side.
(7) When the slope geogrid is filled with two layers of soil, that is, when the thickness is 0.8m, a layer of geogrid shall be laid on both sides at the same time, and so on until it is laid under the soil on the surface of the shoulder.
(8) After the subgrade is filled, the slope shall be repaired in time, and the dry rubble protection at the slope toe shall be carried out. In addition to widening 0.3m on each side of the subgrade, 1.5% settlement shall be reserved.
