Geosynthetic Design Parameters: PVC_geomembrane
Geosynthetic engineering design parameters per AASHTO M288-21, FHWA NHI-07-092, and GRI standards — geotextiles (woven, nonwoven), geogrids (uniaxial, biaxial, triaxial), geomembranes (HDPE, LLDPE, PVC), GCL, geocomposite drains, and erosion control mats with tensile strength, reduction factors, hydraulic properties, and survivability classes
| product type | application class | CBR puncture N min (N) | application | chemical resistance | elongation at break pct min | elongation at break pct typical | expected design life years (years) | notes | reduction factor creep (dimensionless) | reduction factor durability (dimensionless) | reduction factor installation damage (dimensionless) | survivability class | tensile strength kN per m min (kN/m) | tensile strength kN per m typical (kN/m) | test methods | thickness mm typical (mm) |
