Mirafi Pavement Interlayers
Mirafi Pavement Interlayers

Pavement Interlayers for Asphalt Reinforcement
Mirafi interlayers control cracking, reinforce asphalt, and extend pavement durability.
Nexterra's Mirafi pavement interlayers redefine performance in asphalt reinforcement. Engineered to absorb stress, resist cracking, and shield against moisture intrusion, these materials strengthen overlays and extend the life of pavements under the heaviest traffic demands. Each interlayer becomes a critical structural layer, transforming conventional resurfacing into a durable, high-performance pavement system that endures through years of environmental and mechanical stress.
Versatile Applications for Projects
From residential streets to interstate highways, Mirafi interlayers adapt to a full range of asphalt and aggregate conditions. Their advanced construction distributes stress, enhances overlay bonding, and preserves smoothness through constant loading and temperature change. Designed for longevity, they elevate every project from routine rehabilitation to long-term infrastructure renewal.
- Reinforces and stabilizes cracked or fatigued asphalt, delaying reflective cracking and improving surface resilience.
- Strengthens areas with concentrated loading, such as curb and gutter transitions, to prevent premature surface wear.
- Improves bonding and fatigue resistance across overlays, ensuring consistent performance under variable climate conditions.
Reflective Cracking Solutions
As traffic intensity and thinner asphalt mixes increase surface strain, reflective cracking has become one of the most persistent threats to pavement longevity. Mirafi interlayers counter this challenge through superior stress absorption, tensile strength, and waterproofing that work together to preserve pavement continuity.
- Stress-relief fabrics dissipate tensile forces and interrupt crack migration, maintaining a smoother, longer-lasting surface.
- Reinforced interfaces strengthen the bond between overlay and substrate, improving structural integrity under dynamic loading.
- Proven performance extends rehabilitation cycles and reduces lifecycle costs, protecting both budgets and roadways over time.
Advanced Interlayer Technology
Mirafi's technology integrates multiple engineering functions—reinforcement, filtration, and moisture management—into one continuous layer. Each product is field-tested to perform under diverse environmental conditions while optimizing pavement life and constructability.
- Mirafi MPV paving fabric: forms a stress-absorbing, waterproof membrane that prevents water infiltration and enhances overlay adhesion.
- Mirafi PGM-G composite grid: merges glass-fiber reinforcement with nonwoven fabric, providing exceptional tensile strength and crack control in high-traffic corridors.
- Interlayer composites: replace several inches of asphalt while reducing installation time, conserving resources, and maintaining equal or superior strength.
Across North America, Mirafi geosynthetics have set the standard for asphalt reinforcement. Their performance-proven designs help reduce deformation, enhance load-bearing efficiency, and extend pavement service life under the most demanding roadway conditions.
Upstream and Downstream Flow Alignment
Every Mirafi interlayer interacts with the pavement system as a dynamic element of flow, structure, and strength. Installation follows the natural rhythm of drainage and stress movement, ensuring the interlayer bonds completely and performs as an active, balanced layer within the overlay system. By channeling flow energy and structural load along designed paths, Mirafi interlayers maintain consistency from upstream ingress to downstream discharge, preserving uniform performance throughout the pavement section.
- Engineered layering ensures water moves efficiently through controlled flow paths while protecting the subgrade from intrusion.
- Continuous fabric bonding enhances tensile continuity and stabilizes stress distribution across joints and transitions.
- Moisture-barrier function maintains equilibrium under fluctuating conditions, safeguarding long-term structural performance.
- Integrated reinforcement strengthens the overlay's connection to the base, promoting even load transfer and reduced surface fatigue.
- The result is a unified pavement system that performs predictably and endures beyond its design cycle.
Mirafi geosynthetics bring soil, structure, and drainage into balance, creating a unified system that maintains stability, supports performance, and extends the life of every roadway.
Proven Results in the Field
Extensive field performance and independent testing confirm the structural advantages of Mirafi pavement interlayers. By reinforcing overlays and reducing tensile strain, these systems have demonstrated substantial gains in pavement longevity and cost efficiency across diverse climates and traffic conditions. Real-world results show measurable improvements that engineers can trust:
- Reflective cracking reduced by up to 50 percent in rehabilitated surfaces
- Equivalent structural strength to multiple inches of added asphalt thickness
- Extended overlay life cycles that lower total rehabilitation costs year after year
These outcomes reflect a clear performance advantage—practical, tested, and validated in both municipal and highway infrastructure applications.
Sustainability in Practice
Beyond performance, Mirafi interlayers support sustainable construction by reducing material consumption and extending the lifespan of existing infrastructure. Each installation lessens the need for thick overlays, conserves aggregates and asphalt binders, and minimizes carbon emissions associated with frequent resurfacing. The result is an engineered system that delivers both environmental and economic efficiency:
- Reduced use of raw materials through thinner overlays and extended maintenance intervals
- Lower emissions from fewer reconstruction cycles and reduced hauling requirements
- Sustainable reinforcement strategy that aligns with modern pavement preservation goals
Mirafi geosynthetics embody the balance between long-term strength and environmental responsibility, supporting infrastructure that performs efficiently and endures responsibly.
