High Strength Polypropylene Geotextile 300g 600g 800g 1000g Non-Woven Short Fiber Needle Punched Woven Geotextile Cushion Layer Gravel Permeable Geotextile

Product Description

Polypropylene geotextile is the core geosynthetic material for highway and railway subgrade engineering. With its technical characteristics of adapting to transportation infrastructure, it plays an irreplaceable role in key links such as subgrade reinforcement, drainage, and isolation, providing a basic guarantee for the long-term stable operation of the line.
At the material level, it is made of polypropylene fiber by needle punching or hot sticking process. It has excellent chemical stability, acid and alkali resistance, salt corrosion resistance, microbial erosion resistance, and can withstand various corrosive media in the subgrade soil. At the same time, it has outstanding UV resistance and aging resistance, and can adapt to long-term outdoor exposure, soil burial and other complex environments, matching decades of service cycle of traffic engineering.
In terms of mechanical properties, polypropylene geotextile has high fracture strength (longitudinal ≥ 15kN/m, transverse ≥ 12kN/m) and moderate elongation (≥ 40%), which can effectively disperse the vehicle load and soil self weight stress borne by the roadbed, suppress uneven settlement of the roadbed, especially suitable for high-frequency rutting impact on highways and strict requirements for railway heavy load transportation, and enhance the overall bearing capacity of the roadbed. At the same time, its porous structure endows it with good permeability, which can quickly guide the seepage and rainwater inside the roadbed, avoid the softening and strength reduction of the base caused by waterlogging, and ensure the dryness and stability of the roadbed; It has a reliable isolation function, which can prevent the mixing of roadbed fillers with foundation soil and fillers of different particle sizes, maintain the integrity of the roadbed layered structure, and prevent roadbed deformation caused by the loss of fine particles.
 

Product Description

1. Strong corrosion resistance



Polypropylene nonwoven geotextiles have good corrosion resistance and can resist the erosion of chemicals such as acids, alkalis, and salts. They will not corrode due to long-term exposure to harsh environments.
 

 

2. High tensile strength



Polypropylene nonwoven geotextiles have high tensile strength, can withstand large tensile forces, and are not easy to break. The tensile strength of this material is much higher than that of traditional geotechnical materials, which can meet the needs of various engineering projects.

3. Good permeability



Polypropylene nonwoven geotextile has good permeability, allowing water to pass through without hindering its flow. The permeability of this material can ensure the drainage of the soil and prevent soil liquefaction due to excessive moisture.

 

4. Good aging resistance



Polypropylene nonwoven geotextiles have good aging resistance and can be used for a long time without aging. The aging resistance of this material can ensure the long-term stability of the project and will not lead to project failure due to material aging.

Installation Instructions

1. Firstly, the road surface should be cleaned to ensure that there are no debris on it, and it is even better to clean it with clean water. Repair cracks larger than 0.6cm on the road surface, and the repair materials can be asphalt concrete, asphalt sand, or cement mixed soil according to different situations.
2. Hot asphalt distributor can be used to spray adhesive layer oil on the road surface, and the amount of oil can depend on the oil absorption rate of the road surface. The general dosage is between 0.9-1.2kg/m2, and asphalt with an oil grade of 60 or above is generally used.
 

 

3. When laying geotextiles, it is necessary to ensure that the roll material is at a certain height on the ground. After the non-woven geotextile is tensioned and straightened, it is then bonded with the adhesive layer oil, brushed with a brush, and rolled with a steel roller.
4. After the fabric is fully combined with the adhesive layer oil, sprinkle non crushed stones on it. Non crushed stones are usually made of melon seed flakes or medium coarse sand. The amount of crushed stones depends on the oil leakage on the surface of the fabric, usually around 2m3/km2.
5. When laying geotextiles on a large area, fixed devices can be considered at the horizontal overlap of the fabric depending on the specific situation.
