Several geosynthetics manufacturers have developed new products with high surface friction characteristics for capping steep slopes. One such product has been developed that will satisfy not only surface friction problems but also resistance to localized subsidence and puncture. This product is currently manufactured by laminating a sheet of chlorosulfonated polyethylene (CSPE) with a nonwoven geotextile on one or both sides of the CSPE. This paper describes the technical considerations in product development and presents results of two special large scale geosynthetic test methods use to evaluate both surface friction characteristics and stress-strain response due to subsidence.
