Cost-Effective Haul Road Reinforcement with Neoloy® Tough-Cells

Neoloy® Tough-Cell haul road reinforcement keeps the heavy haul trucks moving over all kinds of 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. 

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 rigid Neoloy geocells 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 making them the safest and most economical solution with the lowest operations. 

The unique, validated properties of the Neoloy Tough-Cell reinforcement factors 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, offering 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.

Logging & Forestry Road Stabilization

Stabilize Forest and Logging Roads with Strong, Sustainable and Smart Solution 

Neoloy® Tough-Cells create all-weather, sustainable logging roads and log yards on any type of terrain, to increase handling, safety and productivity. 

Forests are typically located in regions with mountainous terrain and soft, wet, silty soils. Forest roads require quality design, construction and maintenance, so that foresters can focus their efforts on land management and harvesting timber and not on road repairs and maintenance. 

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 cellular confinement system used for forest road stabilization meets these challenges – with all-weather installation and all-weather road use in soft and saturated soils. The Neoloy Tough-Cell solution creates sustainable forest service roads and logging roads, with a small environmental imprint, using locally available soils for construction. 

Logistics is simple as the tough cells arrive onsite in folded sections. These are easily laid out, filled with locally won granular soil, and compacted for immediate use, even by heavy tracked skidders. Subgrade excavation can be reduced or eliminated, while foresters won’t have to sacrifice part of the tree harvest to build log (corduroy) roads, or haul in engineered aggregate. 

Neoloy Tough-Cell are designed in a way that they are the stiffness, strongest and with the highest resistance solution compared to all kind of solutions, making them the best management practice for forest roads and logging roads. Neoloy-based Tough-Cell reinforced roads maintain the gravel road surface courses and resist rutting under a load of heavy logging vehicles. This also helps to prevent sedimentation from forest roads in watershed-sensitive areas. 

Forest service roads in nature reserves and national parks can be constructed where the minimization of both the environmental footprint and maintenance is critical. Logging roads for timber production are strong, durable and all-weather to improve harvesting production with minimal environmental impact. The fact that forest road structural thickness can be halved while using locally available soil for infill also cuts construction time as well as costs.

Sustainable Road Construction

Sustainable road construction is a practice that prioritizes minimizing the environmental impact of road infrastructure while ensuring its durability and functionality. It involves using environmentally friendly materials, reducing energy consumption, and preserving natural resources. Neoloy Tough-Cell geocells are a sustainable solution. 

Neoloy® Tough-Cell Sustainable Solution

Neoloy is a unique sustainable and proven pavement solution for durable road infrastructure that minimizes environmental impacts, recycles materials and takes total lifetime costs into account:

Neoloy Tough-Cells reduce the amount of aggregate in road construction by improving the stiffness and strength of local but marginal soils and recycled materials. This lowers environmental impacts and the carbon footprint significantly. The results are greener construction, with very long-term durability (and reduced maintenance) for any road, rail or port infrastructure project. At the same time, Neoloy also improves pavement performance, lifespan and cost-effectiveness all at the same time.

Why The Neoloy® Tough-Cell for Sustainable Road Construction

Neoloy Tough-Cells 3D mechanical confinement system improves the modulus of marginal infill materials Locally available, but poorly graded or partially cohesive marginal soils (e.g., sand) can be used for structural and support layers, as can recycled materials, such as RAP (reclaimed asphalt pavement) and RCA (recycled concrete aggregate). The validated Neoloy reinforcement factor (2.5-5x) also reduces pavement thickness up to 70%, thereby reducing the total amount of infill materials required. These two factors reduce quarrying, hauling, earthworks and soil replacement significantly to create sustainable infrastructure.
