Sustainable Roads

PRS-Neoloy paves the way for more sustainable earthwork and civil engineering infrastructure development.

PRS-Neoloy™ cellular soil confinement systems (geocells) are an excellent example of sustainable techniques used in roads and infrastructure construction. These are based on the Neoloy® novel polymeric alloy, which provides enhanced geocell performance; these have important environmental and economic ramifications.

The increased strength of the PRS-Neoloy geocell improves the bearing capacity in particular for load support. This reduces the number of granular infill materials for base layers in half. Additionally, the 3D confinement of the soil enables the use of on-site or low strength and/or poorly graded infill such as locally available granular material, which is normally unsuitable for reinforcement.

This reduces the number of haul vehicles needed to transport infill, including in placement earthworks, and this, in turn, has direct and indirect environmental and economic benefits: less fuel usage, fewer earthworks, less equipment and manpower, less site disruption and faster construction time. The bottom line is both a lower carbon footprint and lower project costs.

In addition, the increased strength of a Neoloy based geocell extends the service life of the project, thereby achieving another sustainability roads goal. Sustainable roads development social benefits include more reliable and safer transportation, as well as all-weather access to markets, particularity for rural populations. Local work crews can be trained on-site to perform the installation.
