| 摘要： | GSI has a long history of writing specifications for geosynthetics. Like all engineered materials, geosynthetics are used in many applications and need general requirements for plans and specifications. When the NSF ceased servicing NSF #54 "Specification for Geomembranes" in 1991, The Geosynthetic Institute (GSI) was requested by its membership to continue the effort. With a bit of trepidation, we started on high-density polyethylene (HDPE), but only after considerable in-house research and development. Once the specification was finalized in 1997, linear low-density polyethylene (LLDPE) followed in 2000 and then flexible polypropylene (fPP) in 2002. Scrim reinforced polyethylene specifications were adopted between 2003 and 2009 for fPP, LLDPE and medium-density polyethylene (MDPE) as well as for ethylene propylene diene monomer (EPDM) and chlorosulfonated polyethylene (CSPE), both nonreinforced and scrim reinforced. |
