The composite geomembrane is employed for day and night traffic of high-grade highway pavement and bridge pavement. Addition amount: kg / m3, abrasion layer: 3.5kg / m3.

When 2.5 kilograms of asphalt pavement 5000 1.5 special reinforcing fibers are added per kiloliter of asphalt concrete, the composite wholesale HDPE geomembrane has approximately 5000-6000 2.5 per kiloliter of asphalt concrete. There are quite 850 million separated fibers during a three-dimensional structure. it's evenly distributed in> 6000 3.5 asphalt concrete, which provides an honest reinforcement effect for asphalt concrete, thereby ensuring that asphalt concrete has excellent strength, stability, durability and crack resistance.

Benefit analysis: The lastingness of the composite geomembrane is greatly improved. a rise of about 15% can improve the oil permeability. If the quantity of asphalt is that the same, the void ratio will increase, which can help improve the steadiness of the asphalt concrete. It can increase by 0.3%. When laying the film, it must be laid from top to bottom.

The film should be pressed tightly between the film and therefore the base surface, but it shouldn't be pulled too tight. Generally, it should be slightly loose, but there should be no air bubbles at the rock bottom of the film. Because the geomembrane is comparatively thin and lightweight, it's easy to be blown by the wind before the protective layer is laid, therefore the area of one film shouldn't be large, and it's best to hide the protective earth with the film.

According to the knowledge provided by the manufacturer, the width of the composite geomembrane is 1.0 ~ 1.9m. This project uses a width of 1.9m to scale back the joint material. The joints have methods like hot sticking, gluing, lap jointing, etc. This project is meant with gluing, and therefore the joint width is 50mm. Now there's a replacement sort of composite geomembrane-warp knitted composite textured geomembrane factory price.

The warp-knitted composite geomembrane may be a new sort of geotechnical material made from man-made fiber (or glass fiber) as a reinforcing material and compounded with a composite geomembrane.

Warp-knitted composite geomembrane is different from the general composite geomembrane. the most important feature is that the intersections of the warp and weft aren't curved and that they are during a flat state.

Tie the 2 together firmly with a binding line, which may be synchronized more comprehensively and uniformly, withstand external forces and distribute stress, and when the external force is applied to tear the fabric, the yarn will gather along the initial crack, increasing the tear resistance.

When the warp knitting is combined, the warp knitting yarn is employed to repeatedly pass between the warp, weft yarn and therefore the fiber layer of the needle-punched non-woven waterproof geotextile, in order that the three are knitted into one. Therefore, the warp-knitted composite geomembrane not only has the characteristics of high lastingness and low elongation but also has the waterproof performance of the composite geomembrane.
