Geosynthetic Design Parameters: geocomposite_drain
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 | application | chemical resistance | expected design life years (years) | notes | reduction factor creep (dimensionless) | reduction factor durability (dimensionless) | reduction factor installation damage (dimensionless) | test methods | thickness mm typical (mm) | transmissivity m2 per s (m2/s) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| geocomposite_drain | drainage#25.0mm | drainage | Good resistance to most soil chemicals at ambient temperature | 25 | Prefabricated geocomposite drain (PGD); geonet or cuspated core with nonwoven geotextile filter; transmissivity 0.001-0.01 m2/s at 10 kPa compressive load; typical for wall drainage and cap drainage layer; thickness 8-25 mm core | 1 | 1.05 | 1.2 | ASTM D4716 (transmissivity); ASTM D4491 (geotextile permittivity); ASTM D4833 (geotextile puncture) | 25 | 0.001 |
| geocomposite_drain | retaining_wall_drainage#10.0mm | retaining_wall_drainage | Good resistance to most soil chemicals at ambient temperature | 25 | Thin geocomposite drain for retaining wall drainage; transmissivity 0.003-0.01 m2/s; core thickness 8-12 mm; single-sided geotextile filter; replaces granular drainage layer behind retaining walls | 1 | 1.05 | 1.2 | ASTM D4716; ASTM D4491 | 10 | 0.003 |
