PET Filament Singeing Geotextile

Filament singeing Geotextile

 

Filament singed Geotextile is a new type of excellent geotextile for strengthening pavement and subgrade. This product is made of polyester viscose filament Geotextile singeing on one side. It has high tensile strength in both horizontal and vertical directions, high elastic modulus, and excellent resistance to high and low temperatures. After surface coating treatment, it has excellent alkali resistance and aging resistance, and is widely used for the reinforcement of asphalt pavement, cement concrete pavement, and roadbed. Both hard and flexible road surfaces are suitable, which can reduce cost, extend service life, and prevent road reflection cracks compared to traditional road surfaces.

 

1、 Singeing Geotextile product specification

2-6 meters wide

50-100 meters long

Weight: 100-800 grams/square meter

2、 Singeing Geotextile product performance

1. This product is made of 100% polyester, with a melting point of over 260 ℃ and no significant shrinkage below 230 ℃. Choosing this product can avoid the potential thermal shrinkage of the fabric at high temperatures when paving the hot asphalt surface layer;

2. This product is non-woven Geotextile made of polyester continuous filament reinforced by needle punching. Its tensile strength is ≥ 8KN/m, and its elongation is 40-60%, which fully meets the technical requirements for Geotextile in JTJ/T019-98 (Technical Specification for Application of Highway Geosynthetics);

3. This product has a moderate thickness and strong ability to impregnate asphalt. It combines with dry layer oil to form an ideal isolation layer and has good waterproof and insulation effects;

4. This product has the ability to resist ultraviolet radiation, cold freezing, chemical corrosion, and biological damage;

5. This product is developed for road surfaces and has a unique patent for single and double sided singeing. When laying, the rough side of the singeing is facing upwards, which not only improves the bonding force between the surface layer and the interlayer, but also prevents being rolled up and damaged by the wheels during construction. At the same time, it can suppress the slipping phenomenon of vehicles and pavers on the cloth;

6. Reduce the bonding force between the surface layer and the interlayer;

7. Relieve stress concentration at cracks and prevent crack development;

8. After impregnating with asphalt, it becomes an impermeable layer to prevent water from softening the road structure.

3、 Use of singeing Geotextile products

1. Isolation

Use Geotextile to isolate building materials (such as soil and sand, sand and gravel, soil and concrete) with different physical properties (large particle size, distribution, consistency and density, etc.). Ensure that there is no loss or mixing between two types of materials, maintain the overall structure and function of the materials, and enhance the load-bearing capacity of the structure;

2. Filtering

When the fine soil layer flows into the coarse soil layer, the needle punched Geotextile with good air permeability and water permeability is used to make the water flow through, and the soil particles, fine sand, small stones, etc. are effectively intercepted to maintain the stability of water and soil engineering;

3. Drainage

Geotextile is a good water conducting material, which can form a drainage channel in the soil body to drain the excess liquid and gas in the soil structure;

4. Reinforcement

Needle punched Geotextile can enhance the tensile strength and deformation resistance of soil, increase the stability of building structure, and improve the quality of soil;

5. Protection

Spread, transfer, or decompose concentrated stress to prevent damage to the diagram due to external forces;

6. Closed

The Geotextile is combined with other materials (mainly asphalt or plastic film) to form an impermeable barrier in the soil layer. (Used for road resurfacing and repair, etc.).

Singeing Geotextile is mainly used for:

1. Water conservancy engineering: seawall, river embankment, and lake embankment compliance engineering; Reservoir reinforcement engineering; Reclamation projects; Flood prevention and rescue;

2. Highway, railway, and airport engineering: soft foundation reinforcement treatment, slope protection, pavement anti reflection crack structural layer, drainage system, and green isolation belt;

3. Electrical engineering: nuclear power plant foundation engineering, thermal power ash dam engineering, hydropower station engineering;

4. Port waterway engineering: Port.
