Differences Between Subgrade Reinforcing Geotextile & Soft Foundation Stabilization Geotextile
Differences Between Subgrade Reinforcing Geotextile & Soft Foundation Stabilization Geotextile
1. Core Design Purpose
·Subgrade Reinforcing Geotextile
Focus on overall structural strengthening of normal road subgrade.
Main target: Evenly distribute vehicle load, isolate filling layers, prevent pavement rutting & reflection cracks, slow down common subgrade deformation.
Applicable to ordinary soil, gravel, slightly soft subgrade, not limited to ultra-weak mud ground.
·Soft Foundation Stabilization Geotextile
Specially customized for ultra-weak saturated soft soil (silt, mucky soil, swamp ground).
Main target: Restrict lateral extrusion of fluid mud, accelerate drainage consolidation of soft soil, control large uneven settlement of deep soft ground.
Solve the core problem of soft soil low bearing capacity.
2. Performance Standard Difference
·Subgrade Reinforcing Geotextile
Gram weight: 200g/m² ~ 500g/m² mainstream
Tensile strength: Medium standard, meet daily traffic load dispersion
Drainage performance: Conventional filtration, only discharge normal seepage water
Burst resistance: Ordinary anti-puncture, adapt to common gravel bedding
·Soft Foundation Stabilization Geotextile
Gram weight: Mostly 400g/m² ~ 800g/m², thicker and heavier
Tensile strength: Higher longitudinal & transverse tensile force, strong anti-deformation capacity to resist lateral soil squeeze
Drainage efficiency: Higher vertical permeability, speed up pore water discharge to consolidate soft mud fast
CBR burst & tear strength: Index upgraded, withstand large settlement and filler extrusion
3. Application Scope Distinction
·Subgrade Reinforcing Geotextile
New & widening reconstruction of ordinary highway, municipal road
Parking lots, factory roads, temporary construction access roads
Slightly soft subgrade, rocky foundation leveling & isolation
Road overlay anti-crack & base separation
·Soft Foundation Stabilization Geotextile
Deep silt, mucky soil, swamp, coastal mud flat road foundation
New embankment filling on large-area soft ground
Port yard, logistics container yard thick soft soil treatment
Sea reclamation, river dyke soft foundation reinforcement
4. Construction Function Difference
·Subgrade Reinforcing Geotextile
Three core functions: Reinforcement + Separation + Conventional Filtration
Mainly prevent mixed interlayer materials and pavement surface diseases.
·Soft Foundation Stabilization Geotextile
Four core functions: High-strength Reinforcement + Rapid Drainage Consolidation + Anti-lateral Slip + Filtration
The drainage consolidation function is the unique core demand that ordinary subgrade reinforcing geotextile cannot replace.
5. Cost & Economy
·Subgrade Reinforcing Geotextile: Lower unit price, widely used in general road projects, cost-effective for conventional subgrade.
·Soft Foundation Stabilization Geotextile: Higher mechanical indicators, higher unit cost, only used for special weak ground engineering.
Simple Summary
·If your road ground is ordinary soil/gravel with slight deformation demand → choose Subgrade Reinforcing Geotextile
·If ground is thick silt, mud, swamp with serious settlement & lateral flow risk → choose Soft Foundation Stabilization Geotextile
