MPG and MPG4
Glass Filament Reinforced Paving Composites
Mirafi® MPG and MPG4 are glass filament reinforced paving composites comprised of fiberglass filament yarn incorporated into a nonwoven polypropylene paving fabric.
Key Features
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).
Sealing
The use of a coating to create an impervious surface.
Adhesive Bonding
Adhering two different surfaces or materials using an adhesive substrate.
Stress Relief
The stress reduction from a geosynthetic while the system is in a state of constant deformation or load.
