Pavement Plastic Compound 100x3.95m Fiberglass Geogrid For Road Construction

Pavment Plastic Compound Grid For Road Construction Fiber Glass Subgrade Geogrid


Glass Fiber Geogrid Introduction

Glass fiber geogrid is a network structure material made of glass fiber alkali free twistless roving as the main raw material and a certain weaving process. In order to protect glass fiber and improve the overall use of polyester geogrid, high-strength Hai Lun industrial filament is used to warp knit directional weaving grid blank cloth and coated to form geogrid.
Geotextile is used for highway, railway, tunnel, dam and tailings treatment, isolation, filtration, drainage, reinforcement, protection and enhancement
The causes of cracks in asphalt overlay are analyzed, and a new and excellent geotechnical base material is formed through special coating process.

Glass Fiber Geogrid Specification:

Glass Fiber Geogrid Features:

Improve the high temperature rutting resistance of asphalt concrete pavement. Under the influence of many factors, it is easy to reduce the high-temperature stability of asphalt mixture, resulting in rutting - which will affect the driving comfort, and even have hidden dangers of traffic safety. The application of Geogrid in asphalt concrete pavement can improve the support capacity of asphalt concrete pavement, so as to add a layer of guarantee for traffic safety. In addition, adding geogrid in asphalt mixture can strengthen the bearing capacity of asphalt concrete pavement, and geogrid, as an independent anchor point, limits the displacement of aggregate, so that the interaction between asphalt mixture and grid is of great significance to improve the stability of mineral aggregate framework.

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.
