PRODUCT DETAILS

High-Strength Material Structure

Premium Material & Advanced Manufacturing
Engineered with high-molecular-weight, low-CEG polyester yarns knitted in orthogonal directions and bonded with lightweight PET/PP spunbond nonwoven fabric. The bituminous coating enhances structural integrity and chemical resistance for long-term pavement performance.

Excellent Reinforcement Performance

Improving Bearing Capacity and Structural Stability
High tensile strength with low creep effectively reinforces asphalt layers, preventing reflective cracking from the subgrade. The composite stabilizes the base course while minimizing incremental plastic deformation under heavy traffic loads.

Effective Separation and Drainage Function

Filtration and Pore Pressure Dissipation
The integrated nonwoven geotextile performs separation, filtration, and in-plane drainage. It prevents fine soil migration from the subgrade into the base course while accelerating excess pore water pressure dissipation in saturated conditions.

Cost-Efficient Installation

Straightforward Application and Project Flexibility
Available in multiple roll widths from 1m to 5.95m to match project requirements. Easy to fix with tack coat spray, ensuring seamless connection between upper and lower asphalt layers without separation, reducing maintenance intervals significantly.
