Mirafi® MPG is a glass filament reinforced paving composite comprised of fiberglass filament yarn incorporated into a nonwoven polypropylene paving fabric. This composite or reinforced paving fabric combines the excellent reinforcing properties of glass filaments with optimum liquid asphalt retention capacity of a mechanically bonded AASHTO nonwoven paving fabric.
The Difference Mirafi® MPG Paving Composite Makes:
- Reinforcement: High load-properties at low strain (<3%) appropriate for heavy loaded pavements.
- Cost Effectiveness: Suitable for full width overlay, local patch and joint repair.
- Sealing: Moisture cannot penetrate into the road structure.
- Longevity: Maintenance intervals are considerably extended.
- Stress Relief: Retards crack propagation from the old surface to the new overlay.
- Adhesive Bonding: Provides uniform bonding between old and new asphalt layers.
- Installation: Easily included in asphalt resurfacing projects.
- Recycling: Can be milled with conventional milling machines.
- Resistance: Chemically resistant to road salt.
Functions
Reinforcement
The synergistic improvement of a total system’s strength created by the introduction of a reinforcing geosynthetic (that is good in tension) into a soil and/or aggregate system (that is good in compression but poor in tension).
Reflective Crack Management
The stress reduction from a geosynthetic while the system is in a state of constant deformation or load.
Moisture Barrier
The use of a coating to create an impervious surface.
Rehealing
Adhering two different surfaces or materials using an adhesive substrate.
