Характеристики

Durability: Geotextiles are made of high-quality materials, offering strong durability and anti-aging performance, ensuring long-term effectiveness.

Ease of Construction: Geotextiles are highly flexible and adaptable, allowing for easy cutting and splicing to suit various complex terrains during construction.

Cost-Effectiveness: Compared to traditional impermeable materials, geotextiles are more affordable, significantly reducing the cost of highway projects.

Функция

Усиление: In road and railway construction, geotextiles enhance soil tensile strength and stability, preventing deformation or collapse under heavy vehicle or train loads.

Separation: Geotextiles act as a barrier between soil layers with differing properties, preventing intermixing and ensuring long-term structural integrity.

Drainage: Geotextiles facilitate water drainage in road or railway subgrades, preventing water accumulation that could weaken stability and durability.
