Ferguson’s geosynthetic solutions for cost-effective, durable, and sustainable pavement construction.
“I need to build a longer-lasting pavement without relying on chemical stabilization. My base material is expensive, and I’m looking for a more economical solution that can handle heavy traffic loads.” — Contractor
Flexible (asphalt) pavements are widely used in municipal, commercial, and industrial applications. But they’re also vulnerable to early failures—especially when built over weak subgrades or subjected to heavy traffic. Below, we outline the most common contractor challenges and how Ferguson’s geosynthetic solutions help solve them with smarter design, lower material costs, and better long-term performance.
Key Challenges & Ferguson’s Solutions
Challenge 1: Seeking alternatives to chemical stabilization (lime, cement, fly ash).
Chemical stabilizers increase cost and complexity. They require moisture and cure-time control, add permitting constraints, and can pose environmental concerns. In many projects, owners prefer a more sustainable or faster alternative.
Available Solutions:
- Geogrids (e.g., Tensar InterAx®): Primary solution. Reinforce subgrade soils mechanically, reducing the need for chemical stabilizers by distributing loads and minimizing deformation.
- High-Performance Geotextiles (e.g., Mirafi® H2Ri): Provide separation and filtration, enhancing subgrade stability and reducing moisture-related issues without chemical additives.
Challenge 2: Need for a more economical pavement section.
Traditional flexible pavement sections often require thick aggregate bases or full-depth asphalt, both of which drive up project costs. Finding ways to reduce material thickness without sacrificing strength is essential to keeping projects under budget.
Available Solutions:
- Geogrids (e.g., Tensar InterAx®): Allow for thinner aggregate layers by improving load distribution, leading to cost savings on materials and construction.
- High-Performance Geotextiles (e.g., Mirafi® H2Ri): Enhance the performance of existing materials, enabling the use of locally available aggregates and reducing overall project costs.
Challenge 3: Desire for a longer-lasting pavement section.
Asphalt pavements are prone to rutting, cracking, and fatigue—especially under repeated loading or in poor soil conditions. Extending pavement life reduces total lifecycle cost and improves user safety and satisfaction.
Available Solutions:
- Interlayers (e.g., Huesker HaTelit® Series): Installed between pavement layers to mitigate reflective cracking and extend the lifespan of asphalt surfaces.
- Geogrids (e.g., Tensar InterAx®): Improve structural integrity, reducing maintenance needs and prolonging pavement life.
- High-Performance Geotextiles (e.g., Mirafi® H2Ri): Maintain separation and drainage, preventing subgrade degradation and enhancing durability.
Can geosynthetics also improve environmental sustainability?
Yes. By reducing the need for chemical stabilizers and allowing for the use of local materials, geosynthetics lower the environmental impact of pavement construction. Additionally, their durability leads to fewer repairs and less resource consumption over time.
