A review of published research on NPA (Novel Polymeric Alloy) Geocells in the Indian Geotechnical Journal, Kief, et al (2014) demonstrates how technological innovation in geosynthetics such as NPA Geocells can achieve a more sustainable highway infrastructure. Studies and field tests validate that NPA (Neoloy®) Geocells improve road base modulus by 2.75x and reduce structural thickness by 50% while using marginal or recycled materials for structural infill. In addition to reducing the use of virgin resources, the environmental footprint, and maintenance expenditures, roads built with NPA Geocells can lower total life cycle costs by 20% or more.
