Sort out those soft spots on your roads with new geocell technologies.
Forest roads are often characterised by having lower design standards than public roads. When our roads have weak sub-grades or we use poor strength surfacing material, the result can be continual problems and reactive maintenance. One of the solutions for foresters in these situations is the use of new technology geocell solutions. PRS, one of the global leaders in soil stabilisation and reinforcement, has developed Neoweb, a geocell that consists of a composite 3D honeycomb structure created by the interaction of infill soil, cell walls and cell geometry. This cellular confinement system technology allows soil compaction to be maintained to provide long term soil reinforcement and reliable structural strength. Neoweb strengthens marginal infill to save surfacing aggregate and costs.
Neoweb is manufactured from Neoloy, a polymeric alloy that is claimed to be stiffer and more durable than other geocells. Due to this, PRS indicate that Neoweb provides more structural geosynthetic reinforcement for the subgrade and/or base of any pavement than any other geosynthetic solution. Neoweb improves the moduli of infill materials which results in strengthened pavement layers. The key benefits of the Neoweb are:
- Road layer thickness and infill can be reduced by up to 50%
- An improved elastic modulus of the road base layer with inferior infill by 3 times or more
- An increased design life of gravel roads
- Having loads distributed over a wider area
- Decreasing settlement by up to 80%
- Reducing vertical stress to the subgrade by up to 50%.
The initial costs of purchase and installation will be more than offset by the reduced long-term maintenance costs on the road. Source: http://www.prs-med.com/
