1、 Asphalt impregnation treatment on the surface of pressure sensitive adhesive of geogrid
The geogrid surface is impregnated with self-adhesive pressure-sensitive adhesive to control the geogrid. Asphalt impregnated self-adhesive pressure-sensitive adhesive on the surface of geogrid is the main geosynthetic material of geogrid. Compared with other geosynthetics, HDPE geomembrane fully shows its authenticity and efficacy. Geogrid is often used as reinforcement material of reinforced earth structure or reinforcement material of aluminum alloy geotextile manufacturer.

Geogrid is divided into four categories: plastic geogrid, steel-plastic geogrid, glass fiber geogrid and glass fiber polyester geogrid. Plastic geogrid is a completely rectangular or rectangular polymer network material formed by progressive shearing. According to the consistency of the extrusion direction during the copy process, it can be divided into two types: one-way shear and two-way extrusion.
It is to punch holes on some polymer plates impacted by extrusion, and then push forward the directional stretching under the premise of cooling. When the crack of geotextile is up to 10% of the roll size, we need to operate the damaged part, and then connect the two earth waves closely. In addition, if the gap on the slope surface is up to 10% of the roll size, the geotextile roll should be removed and replaced with a new roll. The coating material used by the geogrid geomembrane manufacturer in the post-treatment process is targeted at the asphalt composite material manufacturer.
Each fiber is completely covered and fully compatible with asphalt, so as to ensure that the glass fiber geogrid in the asphalt layer will not be cut off from the asphalt composite material, but firmly combined. The geogrid shall be laid on the gentle lower bearing layer according to the prepared spoil size. The filler of the upper base course shall not pierce the debris of the geogrid. When the geogrid is laid, the wind speed is very high to cross the central axis of the embankment. Geogrid is laid longitudinally. The laying shall be tightened to prevent wrinkling, twisting or pitting.
The geogrid is connected horizontally by overlapping method, and the riding size is not more than 20cm. After the geogrid is laid, the manual laying of the upper layer filler shall be completed immediately to prevent exposure to the sun all year round. Then carry out mechanical material transportation, leveling and rolling. The mechanical paving and rolling are carried out from both sides to both sides, and the rolling is carried out from both sides to both sides, and the compactness is maintained to achieve standard elimination.
2、 Geogrid has tensile strength of mild steel
The geogrid rearranges the long chain hydrocarbon molecules of the polymer in a straight line along the stretching direction through a unique technological process. The binding force between the molecular chains is greatly strengthened, so it has higher tensile strength and lower elongation. For example, the tensile strength is 5-10 times higher than that before stretching, and the elongation is only 10% – 15% higher than that before stretching. The interlocking force of particles in the grid increases, and the friction coefficient increases significantly. It can be said that among many geosynthetics, the tensile strength of geogrid is the highest under the same strain, and its tensile strength is close to that of mild steel. In addition to its strong tensile strength, the geogrid also has good durability, because the geogrid material is made of high-density polyethylene or polypropylene plastic as the main raw material, and contains anti-aging additives such as UV and carbon black, which can prevent the erosion of organic solvents such as acid, alkali, salt, alcohol, gasoline and UV. According to relevant data, the service life of geogrid produced by geogrid manufacturers can reach 120 years under normal temperature conditions and design allowable load. Of course, the reason why geogrids are widely used is that the geogrids described below have excellent characteristics. In the slope beautification project, the plastic geocell of the geogrid manufacturer, after the geocell is extended and opened, presents a honeycomb three-dimensional geocell, and fills the geocell with earth and stone or concrete materials to form a structure with strong lateral restraint and large stiffness to form the stability effect on the slope. It can also cultivate some vegetation, or small shrubs and other plants in the geogrid, forming the opposite glass fiber grid is a main geosynthetic material, which has the same performance and effect compared with other geosynthetic materials. The glass fiber grid is often used as reinforcement for reinforced soil structures or composite materials
