Geotextiles are widely utilized in geotechnical engineering for road, slope and earth stabilization. Although primarily used for separation and drainage (filtration), geotextiles also make some contribution to soil reinforcement. This is achieved by allowing water to flow through the geotextile while preventing the movement of soil particles. This preserves the soil integrity, thereby extending the life of the road surface.
However, 3D PRS-Neoweb geocell reinforcement is significantly greater than that of from geotextiles. 2D planer reinforcement provides limited vertical confinement (usually 1-2 times the average size of the granular material). PRS-Neoweb™ cellular confinement systems provide confinement in all directions (i.e., along the entire cross-section of each cell) and has a zone of influence beyond that of the cell height (50-200 mm). Moreover, the multi-cell geometry provides passive resistance that increases the bearing capacity. In addition PRS-Neoweb can provide soil reinforcement to marginal granular materials, such as recycled asphalt, crushed concrete, fly ash and quarry waste. Geotextiles are best deployed for separation and drainage, while PRS-Neoweb is most suitable for soil stabilization and reinforcement.
Benefits of PRS-Neoweb over Geotextiles
- Effective reinforcement – 3D geocell reinforcement mechanisms
- Very high strength and stiffness – tensile strength up to 24 kN/m
- Improves modulus – of infill soil and structural layers
- Longer lifespan – high resistance to deformation under dynamic loading
- Low environmental impact – reduces aggregate use and associated environmental costs
- Sustainable solution – reduced repairs and maintenance due to long pavement life
- Cost effective – lower construction costs and lifecycle costs
