Neoloy®-based PRS-Neoweb™ geocells were specifically developed by PRS for the upper structural reinforcement of load support applications. PRS-Neoweb cellular confinement systems improve the modulus of the structural layers. This enables costly high-quality aggregate to be replaced with less expensive locally-available granular (non-cohesive) infill materials. In addition, the pavement thickness of the structural layers may be reduced and the life-span of structural pavements increased.
The result – lower costs for every square meter of infill. No longer confined to weak subgrade soils with low CBR, PRS-Neoweb tough cells add value to each layer of the structural pavement, even to a base with high CBR.
The base layer may be subject to very high weight or a number of dynamic loadings, as well as elevated temperatures and thermal cycling. The novel Neoloy alloy gives PRS-Neoweb geocells the high dimensional stability to maintain long-term confinement/compaction. In addition, the PRS-Neoweb Modulus Improvement Factor (MIF) allows a reduction in the layer thickness of the asphalt, base and subgrade layers to save even more in a project and life-cycle costs.
