PRS-Neoweb offers cost-effective ground reinforcement solution for railway sub-ballast and ballast layers, rail embankments, turnouts and train yards. Typically placed at the ballast/subgrade interface area, PRS-Neoweb reduces the degradation in track geometry under heavy loads and high traffic.
The cost of railway maintenance (Total Cost of Ownership) determines the success of rail engineering solutions and not construction or rehabilitation costs. PRS-Neoweb soil stabilization in soft soils, including clays, is of great value for new construction and rehabilitation of existing track.
Reduce Track Maintenance
Railways have lain track over sand soils, clay soils and saturated soils with great success in terms of reduced maintenance cycles.
The use of high-strength PRS-Neoweb geocells as a structural support element at the ballast/subgrade interface can reduce surface geometry degradation. Laboratory and full-scale field testing under a range of conditions confirmed that the Neoloy-based geocells decreased the rate of track surface geometry degradation by a factor of 2-2.75 and higher.
Rail track reinforced with PRS-Neoweb geocells increase the maintenance cycles (intervention and tamping cycles), reducing tamping operations required over time and reducing train delay costs. PRS-Neoweb with Neoloy maintains its engineering characteristics and geometry under millions of dynamic loading cycles, unlike HDPE geocells, thereby reducing railway operational and maintenance cost requirements.
