Description
Needle punched nonwoven Geotextiles is a continuous filament nonwoven needle punched polyester paving geotextiles, which provides stress relief, waterproofing and reduces reflective cracking functions in new and existing paved roads. Designed for countries having extreme weather conditions in mind, the product has undergone a number of years of testing and refinement to provide the best overall performance. The unique properties of these Geotextiles provide waterproofing and stress relief of the pavement structure. The high melt temperature of Polyester (PET) ensures that the geotextiles properties are not affected by the application of hot bitumen or asphalt.

1) Specification is decided by mass-area ratio. When the practical specification is between the neighboring specifications in the table, the related check indicators will be calculated according to the interpolation method; if the product specification is beyond the table given scope, the check indicators will be decided by the supplier and demander. | |||||||||||||
Features
1) anti-aging, the product has very high anti-ultraviolet radiation ability, not easy to degradation.
2) High temperature resistance to up to 230℃ maintaining structure stability and original physical properties.
3) High flat drainage and vertical permeability.
4) High creep resistance.
5) Resistance of erosion of chemicals in soil as well as the corrosion of gasoline and diesel etc.
6) High elongation under certain stress, thus able to adapt to uneven and irregular bases.
