Cost-Effective Haul Road Reinforcement with Neoloy® Tough-Cells
Neoloy® Tough-Cell haul road reinforcement keeps the heavy haul trucks moving over the weakest soils in all-weather conditions.
The Challenge for Haul Roads
Haul roads and haul trucks are the lifeline of mining and natural resource extraction industries. That’s why Neoloy Tough-Cell designed for heavy duty pavements can keep your mining haul trucks rolling with soil stabilization and reinforced haul road bases – even in rainy seasons and freeze-thaw cycles.
The Neoloy Solution for Haul Roads
Neoloy Tough-Cells meet these challenges by stiffening haul road pavements using marginal infill material. Keep the haul trucks rolling by stabilizing soft subgrade soils and reinforcing roads with Neoloy for all-weather use. Neoloy Tough-Cell reinforced haul roads resist cuts, impacts and degradation. The result is less wear and tear to tires and vehicles and more efficient, safe and economical mining operations.
The unique and validated properties of the Neoloy Tough-Cell reinforcement factor provide high dynamic stiffness, resistance to permanent degradation and tensile strength. These properties enable Neoloy Tough-Cells to improve the structural and functional behavior of infill materials, with the following benefits:
- Construction of durable haul roads on soft subgrade (sand, peat, organic silts)
- Use of locally available materials (e.g., sand, quarry waste) for structural infill
- A reduction in pavement thickness by 50% with equivalent performance
- Excellent drainage for all weather-construction and all-weather access
These benefits contribute to a lower environmental footprint: less aggregate and hauling, decreased in-situ earthworks and faster construction. Fuel use, fugitive dust and the carbon footprint are all reduced as are construction time and costs.
Why Neoloy Tough-Cells for Haul Roads
Neoloy Tough-Cells is a 3D honeycomb geosynthetic made from Neoloy®. Unlike soft geocells made of HDPE, Neoloy Tough-Cells made of Novel Polymer Alloys (NPA) are designed for durable road solutions – suitable for the mining, logging and energy industries. The creep-resistant and high elastic stiffness properties of the NPA material (meeting international standards for rigid geocells) guarantee reliable haul road soil stabilization for heavy-duty loading. Neoloy’s mechanical confinement locks aggregate and binds soil particles This prevents lateral soil movement resulting from vertical loading, and increases shear resistance and stiffness (Read more about Neoloy technology here). Neoloy Tough-Cell reinforced haul roads resist cuts, impacts and degradation. The result is less wear and tear to tyres and vehicles and more efficient, safe and economic operations for mining operators.
Sustainable Solutions for Mining
PRS Neoloy Tough-Cells are an innovative soil stabilization technology to meet the challenges of mining minerals and earth. Neoloy Tough-Cells keep the haul trucks rolling, enhance waste containment and are a proven method to rehabilitate the landscapes of closed mines for future conservation or community use. Neoloy Tough-Cells sustainable mining solutions improve safety, increase productivity and enhance sustainability.
Haul roads and trucks are the lifeline of natural resource extraction industries. Neoloy Tough-Cell heavy-duty road reinforcement ensures that ore continues to roll 24/7 in all-weather conditions – even over the most problematic conditions. Neoloy Tough-Cells are designed for heavy-duty pavements – with stiffness, low deformation levels and tensile strength suitable for the heaviest of loads (700-800 ton payload). Neoloy Tough-Cells reinforced haul roads provide a durable surface-wearing course that reduces maintenance and enables efficient and economic hauling operations.
Neoloy Tough-Cell integrated with geomembranes creates impermeable, non-slip and durable impoundment for mine waste containment and treatment using one of the following infill types:
- concrete for liquid control
- gravel for leachate treatment processes
- topsoil for landscape restoration
Neoloy Tough-Cells are perfect for sustainable rehabilitation of dry and denuded mine slopes. Its unique frictional resistance, soil-cell interlock and wall strength will keep soil infill and vegetation in place, long after the mine is closed. The Neoloy solution:
- improves ecology – water flow, soil conservation, plant revegetation
- encourages interlocking root growth via perforations, to stabilize soil mass
- enhances landscape, habitat and visual aesthetics
To reinforce steep slopes of surface mines and dry waste stacks, Neoloy confines reinforces and restrains soil and stone infill, which prevents downslope movement from hydrodynamic and gravitational forces. The Neoloy Tough-Cell solution:
- prevents erosion
- increases slope safety
- provides a confined soil structure conducive to plant revegetation
To stabilize surface cuts or prevent erosion in water channel diversions in mining, Neoloy Tough-Cells retaining walls maintain structural stability, even in wet, compressible and unstable subgrades and offer the following advantages:
- increase frictional interaction
- improve drainage
- reduce hydrostatic forces
- enable vegetative growth and green wall face
