Reinforced Geotextile

Product Introduction:

Reinforced Geotextile is a high-performance geosynthetic material composited by high-strength reinforcement materials such as polyester filament or fiberglass and non-woven geotextile through warp knitting or thermal bonding, featuring high tensile strength, low elongation, low creep resistance, excellent puncture and tear resistance, as well as good water permeability, filtration and isolation performance; it integrates the functions of reinforcement, separation, filtration and drainage, effectively disperses structural load, improves the bearing capacity of soft soil foundation, reduces uneven settlement, prevents soil particle loss and pipeline erosion, and is widely applied in highway and railway roadbed reinforcement, old road reconstruction, water conservancy dam and river slope protection, retaining wall filling, soft ground treatment, landfill and tailings pond environmental protection projects, with stable chemical durability, acid and alkali resistance and anti-aging performance, adapting to various complex engineering geological environments.

Product Applications:

In highway construction, the stability of the roadbed directly determines the quality and service life of the highway, and reinforced geotextile is one of the key materials for improving roadbed stability. This material is made of high-strength fibers, is thick and tough, unlike ordinary fabrics which are fragile. It adapts well to the complex environment of highway construction, providing multifaceted protection for the roadbed.

The primary function of reinforced geotextile is to "strengthen the body" of the roadbed. When laid between the soil layers of the roadbed, it adheres tightly to the soil, interlocking with it, like putting a "protective coat" on the loose soil, forming a stable whole. This effectively resists the pressure from vehicle traffic and the soil's own settlement tendency, preventing problems such as roadbed collapse and deformation.

Besides reinforcement, reinforced geotextile can also solve two common problems in roadbed construction—material mixing and water accumulation. Highway subgrades are laid in layers, each using different grades of soil and gravel. Laying reinforced geotextiles clearly separates these different layers, preventing fine soil and gravel from mixing and ensuring each layer provides adequate support. Simultaneously, its numerous tiny pores allow for rapid drainage of water from the subgrade, preventing prolonged waterlogging, softening, frost heave, and soil erosion by rainwater.

In actual highway construction, reinforced geotextiles are used in a wide variety of scenarios, almost anywhere the subgrade is prone to problems. For example, in sections with soft soil and insufficient foundation bearing capacity, laying reinforced geotextiles significantly improves foundation strength and reduces later settlement. For subgrades with high fill, layering geotextiles effectively prevents slippage and cracking. When widening highways, gaps often appear at the junction of new and old subgrades; laying reinforced geotextiles ensures a tighter bond, reducing the likelihood of cracks.

Besides bridge abutments, the junction between bridgeheads and roadbeds is another common application of reinforced geotextiles. Because bridge abutments are rigid concrete structures while roadbeds are relatively soft soil, differential settlement can easily occur at their junction, causing vehicles to bump and jolt—a phenomenon commonly known as bridgehead swaying. Laying reinforced geotextiles reduces this differential settlement, making vehicle travel smoother. Furthermore, roadbed slopes are prone to erosion from rainwater; geotextiles effectively protect against soil erosion and prevent landslides, safeguarding the roadbed's safety.

Moreover, the construction of reinforced geotextiles is not complicated. Workers simply need to clean and compact the roadbed base layer, then lay the geotextile flat on top as required, ensuring appropriate tightness, neat overlaps at joints, and secure securing. Finally, a protective layer and other roadbed materials are laid on top to complete the construction. It is not only convenient to use but also cost-effective, making it an indispensable and practical material for highway roadbed reinforcement.

Reinforced geotextiles are widely used in highway and railway subgrade reinforcement, reconstruction and expansion of old roads, and crack resistance enhancement of asphalt pavements; in water conservancy projects, they are used for river embankments, dams, riverbank protection, canal seepage prevention and cofferdam engineering; they are also suitable for slope protection, reinforced soil retaining walls, bridge abutment backfilling and stabilization; soft soil foundation reinforcement in coastal mudflats, swamps and depressions, and hardening of port terminals and storage yards; they can also be used for isolation filtration and lining protection in landfills, tailings ponds, and chemical waste disposal sites, playing a role in reinforcement and stabilization, isolation and stratification, water permeability filtration, drainage and pressure reduction, effectively reducing foundation settlement and preventing soil slippage and soil erosion.
